Today when using the `splitmuxsrc` on a collection of files named as: ``` item0.mkv item1.mkv item2.mkv [...] item10.mkv item11.mkv [...] ``` You will get a continuous stream made in the order of: ``` item0.mkv -> item1.mkv -> item10.mkv -> item11.mkv -> [...] ``` You can fix this by having smarter names of the items: ``` item000.mkv item001.mkv item002.mkv [...] item010.mkv item011.mkv [...] ``` Will get you: ``` item000.mkv -> item001.mkv -> item003.mkv -> item004.mkv -> [...] ``` But, we could also "fix" the former case by using natural ordering when comparing the files in gstsplitutils.c.

<class name="Bin" c:symbol-prefix="bin" c:type="GstBin" parent="Element" glib:type-name="GstBin" glib:get-type="gst_bin_get_type" glib:type-struct="BinClass">
|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstbin.c">#GstBin is an element that can contain other #GstElement, allowing them to be
|
|
managed as a group.
|
|
Pads from the child elements can be ghosted to the bin, see #GstGhostPad.
|
|
This makes the bin look like any other elements and enables creation of
|
|
higher-level abstraction elements.
|
|
|
|
A new #GstBin is created with gst_bin_new(). Use a #GstPipeline instead if you
|
|
want to create a toplevel bin because a normal bin doesn't have a bus or
|
|
handle clock distribution of its own.
|
|
|
|
After the bin has been created you will typically add elements to it with
|
|
gst_bin_add(). You can remove elements with gst_bin_remove().
|
|
|
|
An element can be retrieved from a bin with gst_bin_get_by_name(), using the
|
|
elements name. gst_bin_get_by_name_recurse_up() is mainly used for internal
|
|
purposes and will query the parent bins when the element is not found in the
|
|
current bin.
|
|
|
|
An iterator of elements in a bin can be retrieved with
|
|
gst_bin_iterate_elements(). Various other iterators exist to retrieve the
|
|
elements in a bin.
|
|
|
|
gst_object_unref() is used to drop your reference to the bin.
|
|
|
|
The #GstBin::element-added signal is fired whenever a new element is added to
|
|
the bin. Likewise the #GstBin::element-removed signal is fired whenever an
|
|
element is removed from the bin.
|
|
|
|
A #GstBin internally intercepts every #GstMessage posted by its children and
|
|
implements the following default behaviour for each of them:
|
|
|
|
* %GST_MESSAGE_EOS: This message is only posted by sinks in the PLAYING
|
|
state. If all sinks posted the EOS message, this bin will post and EOS
|
|
message upwards.
|
|
|
|
* %GST_MESSAGE_SEGMENT_START: Just collected and never forwarded upwards.
|
|
The messages are used to decide when all elements have completed playback
|
|
of their segment.
|
|
|
|
* %GST_MESSAGE_SEGMENT_DONE: Is posted by #GstBin when all elements that posted
|
|
a SEGMENT_START have posted a SEGMENT_DONE.
|
|
|
|
* %GST_MESSAGE_DURATION_CHANGED: Is posted by an element that detected a change
|
|
in the stream duration. The duration change is posted to the
|
|
application so that it can refetch the new duration with a duration
|
|
query.
|
|
|
|
Note that these messages can be posted before the bin is prerolled, in which
|
|
case the duration query might fail.
|
|
|
|
Note also that there might be a discrepancy (due to internal buffering/queueing)
|
|
between the stream being currently displayed and the returned duration query.
|
|
|
|
Applications might want to also query for duration (and changes) by
|
|
listening to the %GST_MESSAGE_STREAM_START message, signaling the active start
|
|
of a (new) stream.
|
|
|
|
* %GST_MESSAGE_CLOCK_LOST: This message is posted by an element when it
|
|
can no longer provide a clock.
|
|
|
|
The default bin behaviour is to check if the lost clock was the one provided
|
|
by the bin. If so and the bin is currently in the PLAYING state, the message
|
|
is forwarded to the bin parent.
|
|
|
|
This message is also generated when a clock provider is removed from
|
|
the bin. If this message is received by the application, it should
|
|
PAUSE the pipeline and set it back to PLAYING to force a new clock
|
|
distribution.
|
|
|
|
* %GST_MESSAGE_CLOCK_PROVIDE: This message is generated when an element
|
|
can provide a clock. This mostly happens when a new clock
|
|
provider is added to the bin.
|
|
|
|
The default behaviour of the bin is to mark the currently selected clock as
|
|
dirty, which will perform a clock recalculation the next time the bin is
|
|
asked to provide a clock.
|
|
|
|
This message is never sent to the application but is forwarded to
|
|
the parent of the bin.
|
|
|
|
* OTHERS: posted upwards.
|
|
|
|
A #GstBin implements the following default behaviour for answering to a
|
|
#GstQuery:
|
|
|
|
* %GST_QUERY_DURATION: The bin will forward the query to all sink
|
|
elements contained within and will return the maximum value.
|
|
If no sinks are available in the bin, the query fails.
|
|
|
|
* %GST_QUERY_POSITION: The query is sent to all sink elements in the bin and the
|
|
MAXIMUM of all values is returned. If no sinks are available in the bin,
|
|
the query fails.
|
|
|
|
* OTHERS: the query is forwarded to all sink elements, the result
|
|
of the first sink that answers the query successfully is returned. If no
|
|
sink is in the bin, the query fails.
|
|
|
|
A #GstBin will by default forward any event sent to it to all sink
|
|
( %GST_EVENT_TYPE_UPSTREAM ) or source ( %GST_EVENT_TYPE_DOWNSTREAM ) elements
|
|
depending on the event type.
|
|
|
|
If all the elements return %TRUE, the bin will also return %TRUE, else %FALSE
|
|
is returned. If no elements of the required type are in the bin, the event
|
|
handler will return %TRUE.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstbuffer.c">Buffers are the basic unit of data transfer in GStreamer. They contain the
|
|
timing and offset along with other arbitrary metadata that is associated
|
|
with the #GstMemory blocks that the buffer contains.
|
|
|
|
Buffers are usually created with gst_buffer_new(). After a buffer has been
|
|
created one will typically allocate memory for it and add it to the buffer.
|
|
The following example creates a buffer that can hold a given video frame
|
|
with a given width, height and bits per plane.
|
|
|
|
``` C
|
|
GstBuffer *buffer;
|
|
GstMemory *memory;
|
|
gint size, width, height, bpp;
|
|
...
|
|
size = width * height * bpp;
|
|
buffer = gst_buffer_new ();
|
|
memory = gst_allocator_alloc (NULL, size, NULL);
|
|
gst_buffer_insert_memory (buffer, -1, memory);
|
|
...
|
|
```
|
|
|
|
Alternatively, use gst_buffer_new_allocate() to create a buffer with
|
|
preallocated data of a given size.
|
|
|
|
Buffers can contain a list of #GstMemory objects. You can retrieve how many
|
|
memory objects with gst_buffer_n_memory() and you can get a pointer
|
|
to memory with gst_buffer_peek_memory()
|
|
|
|
A buffer will usually have timestamps, and a duration, but neither of these
|
|
are guaranteed (they may be set to #GST_CLOCK_TIME_NONE). Whenever a
|
|
meaningful value can be given for these, they should be set. The timestamps
|
|
and duration are measured in nanoseconds (they are #GstClockTime values).
|
|
|
|
The buffer DTS refers to the timestamp when the buffer should be decoded and
|
|
is usually monotonically increasing. The buffer PTS refers to the timestamp when
|
|
the buffer content should be presented to the user and is not always
|
|
monotonically increasing.
|
|
|
|
A buffer can also have one or both of a start and an end offset. These are
|
|
media-type specific. For video buffers, the start offset will generally be
|
|
the frame number. For audio buffers, it will be the number of samples
|
|
produced so far. For compressed data, it could be the byte offset in a
|
|
source or destination file. Likewise, the end offset will be the offset of
|
|
the end of the buffer. These can only be meaningfully interpreted if you
|
|
know the media type of the buffer (the preceding CAPS event). Either or both
|
|
can be set to #GST_BUFFER_OFFSET_NONE.
|
|
|
|
gst_buffer_ref() is used to increase the refcount of a buffer. This must be
|
|
done when you want to keep a handle to the buffer after pushing it to the
|
|
next element. The buffer refcount determines the writability of the buffer, a
|
|
buffer is only writable when the refcount is exactly 1, i.e. when the caller
|
|
has the only reference to the buffer.
|
|
|
|
To efficiently create a smaller buffer out of an existing one, you can
|
|
use gst_buffer_copy_region(). This method tries to share the memory objects
|
|
between the two buffers.
|
|
|
|
If a plug-in wants to modify the buffer data or metadata in-place, it should
|
|
first obtain a buffer that is safe to modify by using
|
|
gst_buffer_make_writable(). This function is optimized so that a copy will
|
|
only be made when it is necessary.
|
|
|
|
Several flags of the buffer can be set and unset with the
|
|
GST_BUFFER_FLAG_SET() and GST_BUFFER_FLAG_UNSET() macros. Use
|
|
GST_BUFFER_FLAG_IS_SET() to test if a certain #GstBufferFlags flag is set.
|
|
|
|
Buffers can be efficiently merged into a larger buffer with
|
|
gst_buffer_append(). Copying of memory will only be done when absolutely
|
|
needed.
|
|
|
|
Arbitrary extra metadata can be set on a buffer with gst_buffer_add_meta().
|
|
Metadata can be retrieved with gst_buffer_get_meta(). See also #GstMeta.
|
|
|
|
An element should either unref the buffer or push it out on a src pad
|
|
using gst_pad_push() (see #GstPad).
|
|
|
|
Buffers are usually freed by unreffing them with gst_buffer_unref(). When
|
|
the refcount drops to 0, any memory and metadata pointed to by the buffer is
|
|
unreffed as well. Buffers allocated from a #GstBufferPool will be returned to
|
|
the pool when the refcount drops to 0.
|
|
|
|
The #GstParentBufferMeta is a meta which can be attached to a #GstBuffer
|
|
to hold a reference to another buffer that is only released when the child
|
|
#GstBuffer is released.
|
|
|
|
Typically, #GstParentBufferMeta is used when the child buffer is directly
|
|
using the #GstMemory of the parent buffer, and wants to prevent the parent
|
|
buffer from being returned to a buffer pool until the #GstMemory is available
|
|
for re-use. (Since: 1.6)</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstbufferpool.c">A #GstBufferPool is an object that can be used to pre-allocate and recycle
|
|
buffers of the same size and with the same properties.
|
|
|
|
A #GstBufferPool is created with gst_buffer_pool_new().
|
|
|
|
Once a pool is created, it needs to be configured. A call to
|
|
gst_buffer_pool_get_config() returns the current configuration structure from
|
|
the pool. With gst_buffer_pool_config_set_params() and
|
|
gst_buffer_pool_config_set_allocator() the bufferpool parameters and
|
|
allocator can be configured. Other properties can be configured in the pool
|
|
depending on the pool implementation.
|
|
|
|
A bufferpool can have extra options that can be enabled with
|
|
gst_buffer_pool_config_add_option(). The available options can be retrieved
|
|
with gst_buffer_pool_get_options(). Some options allow for additional
|
|
configuration properties to be set.
|
|
|
|
After the configuration structure has been configured,
|
|
gst_buffer_pool_set_config() updates the configuration in the pool. This can
|
|
fail when the configuration structure is not accepted.
|
|
|
|
After the pool has been configured, it can be activated with
|
|
gst_buffer_pool_set_active(). This will preallocate the configured resources
|
|
in the pool.
|
|
|
|
When the pool is active, gst_buffer_pool_acquire_buffer() can be used to
|
|
retrieve a buffer from the pool.
|
|
|
|
Buffers allocated from a bufferpool will automatically be returned to the
|
|
pool with gst_buffer_pool_release_buffer() when their refcount drops to 0.
|
|
|
|
The bufferpool can be deactivated again with gst_buffer_pool_set_active().
|
|
All further gst_buffer_pool_acquire_buffer() calls will return an error. When
|
|
all buffers are returned to the pool they will be freed.</doc>

|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstbus.c">The #GstBus is an object responsible for delivering #GstMessage packets in
|
|
a first-in first-out way from the streaming threads (see #GstTask) to the
|
|
application.
|
|
|
|
Since the application typically only wants to deal with delivery of these
|
|
messages from one thread, the GstBus will marshall the messages between
|
|
different threads. This is important since the actual streaming of media
|
|
is done in another thread than the application.
|
|
|
|
The GstBus provides support for #GSource based notifications. This makes it
|
|
possible to handle the delivery in the glib #GMainLoop.
|
|
|
|
The #GSource callback function gst_bus_async_signal_func() can be used to
|
|
convert all bus messages into signal emissions.
|
|
|
|
A message is posted on the bus with the gst_bus_post() method. With the
|
|
gst_bus_peek() and gst_bus_pop() methods one can look at or retrieve a
|
|
previously posted message.
|
|
|
|
The bus can be polled with the gst_bus_poll() method. This methods blocks
|
|
up to the specified timeout value until one of the specified messages types
|
|
is posted on the bus. The application can then gst_bus_pop() the messages
|
|
from the bus to handle them.
|
|
Alternatively the application can register an asynchronous bus function
|
|
using gst_bus_add_watch_full() or gst_bus_add_watch(). This function will
|
|
install a #GSource in the default glib main loop and will deliver messages
|
|
a short while after they have been posted. Note that the main loop should
|
|
be running for the asynchronous callbacks.
|
|
|
|
It is also possible to get messages from the bus without any thread
|
|
marshalling with the gst_bus_set_sync_handler() method. This makes it
|
|
possible to react to a message in the same thread that posted the
|
|
message on the bus. This should only be used if the application is able
|
|
to deal with messages from different threads.
|
|
|
|
Every #GstPipeline has one bus.
|
|
|
|
Note that a #GstPipeline will set its bus into flushing state when changing
|
|
from READY to NULL state.</doc>

|
|
keep a copy of it, call gst_message_ref() before leaving @func.
|
|
|
|
The watch can be removed using gst_bus_remove_watch() or by returning %FALSE
|
|
from @func. If the watch was added to the default main context it is also
|
|
possible to remove the watch using g_source_remove().
|
|
|
|
The bus watch will take its own reference to the @bus, so it is safe to unref
|
|
@bus using gst_object_unref() after setting the bus watch.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstbus.c">Polls the bus for messages. Will block while waiting for messages to come.
|
|
You can specify a maximum time to poll with the @timeout parameter. If
|
|
@timeout is negative, this function will block indefinitely.
|
|
|
|
All messages not in @events will be popped off the bus and will be ignored.
|
|
It is not possible to use message enums beyond #GST_MESSAGE_EXTENDED in the
|
|
@events mask
|
|
|
|
Because poll is implemented using the "message" signal enabled by
|
|
gst_bus_add_signal_watch(), calling gst_bus_poll() will cause the "message"
|
|
signal to be emitted for every message that poll sees. Thus a "message"
|
|
signal handler will see the same messages that this function sees -- neither
|
|
will steal messages from the other.
|
|
|
|
This function will run a #GMainLoop from the default main context when
|
|
polling.
|
|
|
|
You should never use this function, since it is pure evil. This is
|
|
especially true for GUI applications based on Gtk+ or Qt, but also for any
|
|
other non-trivial application that uses the GLib main loop. As this function
|
|
runs a GLib main loop, any callback attached to the default GLib main
|
|
context may be invoked. This could be timeouts, GUI events, I/O events etc.;
|
|
even if gst_bus_poll() is called with a 0 timeout. Any of these callbacks
|
|
may do things you do not expect, e.g. destroy the main application window or
|
|
some other resource; change other application state; display a dialog and
|
|
run another main loop until the user clicks it away. In short, using this
|
|
function may add a lot of complexity to your code through unexpected
|
|
re-entrancy and unexpected changes to your application's state.
|
|
|
|
For 0 timeouts use gst_bus_pop_filtered() instead of this function; for
|
|
other short timeouts use gst_bus_timed_pop_filtered(); everything else is
|
|
better handled by setting up an asynchronous bus watch and doing things
|
|
from there.</doc>

|
|
|
Caps are exposed on #GstPadTemplate to describe all possible types a
|
|
given pad can handle. They are also stored in the #GstRegistry along with
|
|
a description of the #GstElement.
|
|
|
|
Caps are exposed on the element pads using the gst_pad_query_caps() pad
|
|
function. This function describes the possible types that the pad can
|
|
handle or produce at runtime.
|
|
|
|
A #GstCaps can be constructed with the following code fragment:
|
|
|
|
``` C
|
|
GstCaps *caps = gst_caps_new_simple ("video/x-raw",
|
|
"format", G_TYPE_STRING, "I420",
|
|
"framerate", GST_TYPE_FRACTION, 25, 1,
|
|
"pixel-aspect-ratio", GST_TYPE_FRACTION, 1, 1,
|
|
"width", G_TYPE_INT, 320,
|
|
"height", G_TYPE_INT, 240,
|
|
NULL);
|
|
```
|
|
|
|
A #GstCaps is fixed when it has no fields with ranges or lists. Use
|
|
gst_caps_is_fixed() to test for fixed caps. Fixed caps can be used in a
|
|
caps event to notify downstream elements of the current media type.
|
|
|
|
Various methods exist to work with the media types such as subtracting
|
|
or intersecting.
|
|
|
|
Be aware that until 1.20 the #GstCaps / #GstStructure serialization into string
|
|
had limited support for nested #GstCaps / #GstStructure fields. It could only
|
|
support one level of nesting. Using more levels would lead to unexpected
|
|
behavior when using serialization features, such as gst_caps_to_string() or
|
|
gst_value_serialize() and their counterparts.</doc>

WARNING: This function takes a `const GstCaps *`, but returns a
|
|
non-const `GstStructure *`. This is for programming convenience --
|
|
the caller should be aware that structures inside a constant
|
|
#GstCaps should not be modified. However, if you know the caps
|
|
are writable, either because you have just copied them or made
|
|
them writable with gst_caps_make_writable(), you may modify the
|
|
structure returned in the usual way, e.g. with functions like
|
|
gst_structure_set().</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstcapsfeatures.c">#GstCapsFeatures can optionally be set on a #GstCaps to add requirements
|
|
for additional features for a specific #GstStructure. Caps structures with
|
|
the same name but with a non-equal set of caps features are not compatible.
|
|
If a pad supports multiple sets of features it has to add multiple equal
|
|
structures with different feature sets to the caps.
|
|
|
|
Empty #GstCapsFeatures are equivalent with the #GstCapsFeatures that only
|
|
contain #GST_CAPS_FEATURE_MEMORY_SYSTEM_MEMORY. ANY #GstCapsFeatures as
|
|
created by gst_caps_features_new_any() are equal to any other #GstCapsFeatures
|
|
and can be used to specify that any #GstCapsFeatures would be supported, e.g.
|
|
for elements that don't touch buffer memory. #GstCaps with ANY #GstCapsFeatures
|
|
are considered non-fixed and during negotiation some #GstCapsFeatures have
|
|
to be selected.
|
|
|
|
Examples for caps features would be the requirement of a specific #GstMemory
|
|
types or the requirement of having a specific #GstMeta on the buffer. Features
|
|
are given as a string of the format `memory:GstMemoryTypeName` or
|
|
`meta:GstMetaAPIName`.</doc>

%GST_CAPS_INTERSECT_ZIG_ZAG tries to preserve overall order of both caps
|
|
by iterating on the caps' structures as the following matrix shows:
|
|
|
|
```
|
|
caps1
|
|
+-------------
|
|
| 1 2 4 7
|
|
caps2 | 3 5 8 10
|
|
| 6 9 11 12
|
|
```
|
|
|
|
Used when there is no explicit precedence of one caps over the other. e.g.
|
|
tee's sink pad getcaps function, it will probe its src pad peers' for their
|
|
caps and intersect them with this mode.
|
|
|
|
%GST_CAPS_INTERSECT_FIRST is useful when an element wants to preserve
|
|
another element's caps priority order when intersecting with its own caps.
|
|
Example: If caps1 is `[A, B, C]` and caps2 is `[E, B, D, A]`, the result
|
|
would be `[A, B]`, maintaining the first caps priority on the intersection.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstchildproxy.c">This interface abstracts handling of property sets for elements with

children. Imagine elements such as mixers or polyphonic generators. They all

have multiple #GstPad or some kind of voice objects. Another use case are
|
|
container elements like #GstBin.
|
|
The element implementing the interface acts as a parent for those child

objects.
|
|
|
|
By implementing this interface the child properties can be accessed from the

parent element by using gst_child_proxy_get() and gst_child_proxy_set().
|
|
|
|
Property names are written as `child-name::property-name`. The whole naming

scheme is recursive. Thus `child1::child2::property` is valid too, if

`child1` and `child2` implement the #GstChildProxy interface.</doc>

Similar to gst_child_proxy_get_child_by_name(), this method

searches and returns a child given a name. The difference is that

this method allows a hierarchical path in the form of

child1::child2::child3. In the later example this method would

return a reference to child3, if found. The name should be made of

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstclock.c">GStreamer uses a global clock to synchronize the plugins in a pipeline.
|
|
Different clock implementations are possible by implementing this abstract
|
|
base class or, more conveniently, by subclassing #GstSystemClock.
|
|
|
|
The #GstClock returns a monotonically increasing time with the method
|
|
gst_clock_get_time(). Its accuracy and base time depend on the specific
|
|
clock implementation but time is always expressed in nanoseconds. Since the
|
|
baseline of the clock is undefined, the clock time returned is not
|
|
meaningful in itself, what matters are the deltas between two clock times.

The time returned by a clock is called the absolute time.
|
|
|
|
The pipeline uses the clock to calculate the running time. Usually all
|
|
renderers synchronize to the global clock using the buffer timestamps, the
|
|
#GST_EVENT_SEGMENT events and the element's base time, see #GstPipeline.
|
|
|
|
A clock implementation can support periodic and single shot clock
|
|
notifications both synchronous and asynchronous.
|
|
|
|
One first needs to create a #GstClockID for the periodic or single shot
|
|
notification using gst_clock_new_single_shot_id() or
|
|
gst_clock_new_periodic_id().
|
|
|
|
To perform a blocking wait for the specific time of the #GstClockID use
|
|
gst_clock_id_wait(). To receive a callback when the specific time is reached
|
|
in the clock use gst_clock_id_wait_async(). Both these calls can be
|
|
interrupted with the gst_clock_id_unschedule() call. If the blocking wait is
|
|
unscheduled a return value of #GST_CLOCK_UNSCHEDULED is returned.
|
|
|
|
Periodic callbacks scheduled async will be repeatedly called automatically
|
|
until they are unscheduled. To schedule a sync periodic callback,
|
|
gst_clock_id_wait() should be called repeatedly.
|
|
|
|
The async callbacks can happen from any thread, either provided by the core
|
|
or from a streaming thread. The application should be prepared for this.
|
|
|
|
A #GstClockID that has been unscheduled cannot be used again for any wait
|
|
operation, a new #GstClockID should be created and the old unscheduled one
|
|
should be destroyed with gst_clock_id_unref().
|
|
|
|
It is possible to perform a blocking wait on the same #GstClockID from
|
|
multiple threads. However, registering the same #GstClockID for multiple
|
|
async notifications is not possible, the callback will only be called for
|
|
the thread registering the entry last.
|
|
|
|
None of the wait operations unref the #GstClockID, the owner is responsible
|
|
for unreffing the ids itself. This holds for both periodic and single shot
|
|
notifications. The reason being that the owner of the #GstClockID has to
|
|
keep a handle to the #GstClockID to unblock the wait on FLUSHING events or
|
|
state changes and if the entry would be unreffed automatically, the handle
|
|
might become invalid without any notification.
|
|
|
|
These clock operations do not operate on the running time, so the callbacks
|
|
will also occur when not in PLAYING state as if the clock just keeps on
|
|
running. Some clocks however do not progress when the element that provided
|
|
the clock is not PLAYING.
|
|
|
|
When a clock has the #GST_CLOCK_FLAG_CAN_SET_MASTER flag set, it can be
|
|
slaved to another #GstClock with gst_clock_set_master(). The clock will
|
|
then automatically be synchronized to this master clock by repeatedly
|
|
sampling the master clock and the slave clock and recalibrating the slave
|
|
clock with gst_clock_set_calibration(). This feature is mostly useful for
|
|
plugins that have an internal clock but must operate with another clock
|
|
selected by the #GstPipeline. They can track the offset and rate difference
|
|
of their internal clock relative to the master clock by using the
|
|
gst_clock_get_calibration() function.
|
|
|
|
The master/slave synchronisation can be tuned with the #GstClock:timeout,
|
|
#GstClock:window-size and #GstClock:window-threshold properties.
|
|
The #GstClock:timeout property defines the interval to sample the master
|
|
clock and run the calibration functions. #GstClock:window-size defines the
|
|
number of samples to use when calibrating and #GstClock:window-threshold
|
|
defines the minimum number of samples before the calibration is performed.</doc>

|
|
|
|
``` C
|
|
time = (internal_time - internal) * rate_num / rate_denom + external
|

```
|
|
|
|
This formula is implemented in gst_clock_adjust_unlocked(). Of course, it
|
|
tries to do the integer arithmetic as precisely as possible.
|
|
|
|
Note that gst_clock_get_time() always returns increasing values so when you
|
|
move the clock backwards, gst_clock_get_time() will report the previous value
|
|
until the clock catches up.</doc>

|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstcontext.c">#GstContext is a container object used to store contexts like a device
|
|
context, a display server connection and similar concepts that should
|
|
be shared between multiple elements.
|
|
|
|
Applications can set a context on a complete pipeline by using
|
|
gst_element_set_context(), which will then be propagated to all
|
|
child elements. Elements can handle these in #GstElementClass::set_context
|
|
and merge them with the context information they already have.
|
|
|
|
When an element needs a context it will do the following actions in this
|
|
order until one step succeeds:
|
|
|
|
1. Check if the element already has a context
|
|
2. Query downstream with %GST_QUERY_CONTEXT for the context
|
|
3. Query upstream with %GST_QUERY_CONTEXT for the context
|
|
4. Post a %GST_MESSAGE_NEED_CONTEXT message on the bus with the required
|
|
context types and afterwards check if a usable context was set now
|
|
5. Create a context by itself and post a %GST_MESSAGE_HAVE_CONTEXT message
|
|
on the bus.
|
|
|
|
Bins will catch %GST_MESSAGE_NEED_CONTEXT messages and will set any previously
|
|
known context on the element that asks for it if possible. Otherwise the
|
|
application should provide one if it can.
|
|
|
|
#GstContext can be persistent.
|
|
A persistent #GstContext is kept in elements when they reach
|
|
%GST_STATE_NULL, non-persistent ones will be removed.
|
|
Also, a non-persistent context won't override a previous persistent
|
|
context set to an element.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstcontrolsource.c">The #GstControlSource is a base class for control value sources that could

|
be used to get timestamp-value pairs. A control source essentially is a
|
|
function over time.
|
|
|
|
A #GstControlSource is used by first getting an instance of a specific
|
|
control-source, creating a binding for the control-source to the target property
|
|
of the element and then adding the binding to the element. The binding will
|
|
convert the data types and value range to fit to the bound property.
|
|
|
|
For implementing a new #GstControlSource one has to implement
|
|
#GstControlSourceGetValue and #GstControlSourceGetValueArray functions.
|
|
These are then used by gst_control_source_get_value() and
|
|
gst_control_source_get_value_array() to get values for specific timestamps.</doc>

|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstelement.c">GstElement is the abstract base class needed to construct an element that
|
|
can be used in a GStreamer pipeline. Please refer to the plugin writers
|
|
guide for more information on creating #GstElement subclasses.
|
|
|
|
The name of a #GstElement can be get with gst_element_get_name() and set with
|
|
gst_element_set_name(). For speed, GST_ELEMENT_NAME() can be used in the
|
|
core when using the appropriate locking. Do not use this in plug-ins or
|
|
applications in order to retain ABI compatibility.
|
|
|
|
Elements can have pads (of the type #GstPad). These pads link to pads on
|
|
other elements. #GstBuffer flow between these linked pads.
|
|
A #GstElement has a #GList of #GstPad structures for all their input (or sink)
|
|
and output (or source) pads.
|
|
Core and plug-in writers can add and remove pads with gst_element_add_pad()
|
|
and gst_element_remove_pad().
|
|
|
|
An existing pad of an element can be retrieved by name with
|
|
gst_element_get_static_pad(). A new dynamic pad can be created using
|
|
gst_element_request_pad() with a #GstPadTemplate.
|
|
An iterator of all pads can be retrieved with gst_element_iterate_pads().
|
|
|
|
Elements can be linked through their pads.
|
|
If the link is straightforward, use the gst_element_link()
|
|
convenience function to link two elements, or gst_element_link_many()
|
|
for more elements in a row.
|
|
Use gst_element_link_filtered() to link two elements constrained by
|
|
a specified set of #GstCaps.
|
|
For finer control, use gst_element_link_pads() and
|
|
gst_element_link_pads_filtered() to specify the pads to link on
|
|
each element by name.
|
|
|
|
Each element has a state (see #GstState). You can get and set the state
|
|
of an element with gst_element_get_state() and gst_element_set_state().
|
|
Setting a state triggers a #GstStateChange. To get a string representation
|
|
of a #GstState, use gst_element_state_get_name().
|
|
|
|
You can get and set a #GstClock on an element using gst_element_get_clock()
|
|
and gst_element_set_clock().
|
|
Some elements can provide a clock for the pipeline if
|
|
the #GST_ELEMENT_FLAG_PROVIDE_CLOCK flag is set. With the
|
|
gst_element_provide_clock() method one can retrieve the clock provided by
|
|
such an element.
|
|
Not all elements require a clock to operate correctly. If the
|
|
#GST_ELEMENT_FLAG_REQUIRE_CLOCK() flag is set, a clock should be set on the
|
|
element with gst_element_set_clock().
|
|
|
|
Note that clock selection and distribution is normally handled by the
|
|
toplevel #GstPipeline so the clock functions are only to be used in very
|
|
specific situations.</doc>

For elements that performed an ASYNC state change, as reported by
|
|
gst_element_set_state(), this function will block up to the
|
|
specified timeout value for the state change to complete.
|
|
If the element completes the state change or goes into

an error, this function returns immediately with a return value of

|
%GST_STATE_CHANGE_SUCCESS or %GST_STATE_CHANGE_FAILURE respectively.

|

returns the current and pending state immediately.
|
|
|

This function returns %GST_STATE_CHANGE_NO_PREROLL if the element
|
|
successfully changed its state but is not able to provide data yet.
|
|
This mostly happens for live sources that only produce data in
|
|
%GST_STATE_PLAYING. While the state change return is equivalent to
|
|
%GST_STATE_CHANGE_SUCCESS, it is returned to the application to signal that
|
|
some sink elements might not be able to complete their state change because
|
|
an element is not producing data to complete the preroll. When setting the
|

element to playing, the preroll will complete and playback will start.</doc>

For elements that performed an ASYNC state change, as reported by

specified timeout value for the state change to complete.

If the element completes the state change or goes into

|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstevent.c">The event class provides factory methods to construct events for sending
|
|
and functions to query (parse) received events.
|
|
|
|
Events are usually created with gst_event_new_*() which takes event-type
|
|
specific parameters as arguments.
|
|
To send an event application will usually use gst_element_send_event() and
|
|
elements will use gst_pad_send_event() or gst_pad_push_event().
|
|
The event should be unreffed with gst_event_unref() if it has not been sent.
|
|
|
|
Events that have been received can be parsed with their respective
|
|
gst_event_parse_*() functions. It is valid to pass %NULL for unwanted details.
|
|
|
|
Events are passed between elements in parallel to the data stream. Some events
|
|
are serialized with buffers, others are not. Some events only travel downstream,
|
|
others only upstream. Some events can travel both upstream and downstream.
|
|
|
|
The events are used to signal special conditions in the datastream such as
|
|
EOS (end of stream) or the start of a new stream-segment.
|
|
Events are also used to flush the pipeline of any pending data.
|
|
|
|
Most of the event API is used inside plugins. Applications usually only
|
|
construct and use seek events.
|
|
To do that gst_event_new_seek() is used to create a seek event. It takes
|
|
the needed parameters to specify seeking time and mode.

protection system can acquire key(s) to decrypt a protected stream.
|
|
|
|
In order for a decryption element to decrypt media
|
|
protected using a specific system, it first needs all the
|
|
protection system specific information necessary to acquire the decryption
|
|
key(s) for that stream. The functions defined here enable this information
|
|
to be passed in events from elements that extract it
|
|
(e.g., ISOBMFF demuxers, MPEG DASH demuxers) to protection decrypter
|
|
elements that use it.
|
|
|
|
Events containing protection system specific information are created using
|
|
#gst_event_new_protection, and they can be parsed by downstream elements
|
|
using #gst_event_parse_protection.
|
|
|
|
In Common Encryption, protection system specific information may be located
|
|
within ISOBMFF files, both in movie (moov) boxes and movie fragment (moof)
|
|
boxes; it may also be contained in ContentProtection elements within MPEG
|

DASH MPDs. The events created by #gst_event_new_protection contain data

identifying from which of these locations the encapsulated protection system

specific information originated. This origin information is required as

some protection systems use different encodings depending upon where the

information originates.
|

The events returned by gst_event_new_protection() are implemented

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstevent.c">Allocate a new qos event with the given values.
|
|
The QOS event is generated in an element that wants an upstream
|
|
element to either reduce or increase its rate because of
|
|
high/low CPU load or other resource usage such as network performance or
|
|
throttling. Typically sinks generate these events for each buffer
|
|
they receive.
|
|
|
|
@type indicates the reason for the QoS event. #GST_QOS_TYPE_OVERFLOW is
|
|
used when a buffer arrived in time or when the sink cannot keep up with
|
|
the upstream datarate. #GST_QOS_TYPE_UNDERFLOW is when the sink is not
|
|
receiving buffers fast enough and thus has to drop late buffers.
|
|
#GST_QOS_TYPE_THROTTLE is used when the datarate is artificially limited
|
|
by the application, for example to reduce power consumption.
|
|
|
|
@proportion indicates the real-time performance of the streaming in the
|
|
element that generated the QoS event (usually the sink). The value is
|
|
generally computed based on more long term statistics about the streams
|
|
timestamps compared to the clock.
|
|
A value < 1.0 indicates that the upstream element is producing data faster
|
|
than real-time. A value > 1.0 indicates that the upstream element is not
|
|
producing data fast enough. 1.0 is the ideal @proportion value. The
|
|
proportion value can safely be used to lower or increase the quality of
|
|
the element.
|
|
|
|
@diff is the difference against the clock in running time of the last
|
|
buffer that caused the element to generate the QOS event. A negative value
|
|
means that the buffer with @timestamp arrived in time. A positive value
|
|
indicates how late the buffer with @timestamp was. When throttling is
|
|
enabled, @diff will be set to the requested throttling interval.
|
|
|
|
@timestamp is the timestamp of the last buffer that cause the element
|
|
to generate the QOS event. It is expressed in running time and thus an ever
|
|
increasing value.
|
|
|
|
The upstream element can use the @diff and @timestamp values to decide
|
|
whether to process more buffers. For positive @diff, all buffers with
|
|
timestamp <= @timestamp + @diff will certainly arrive late in the sink
|
|
as well. A (negative) @diff value so that @timestamp + @diff would yield a
|
|
result smaller than 0 is not allowed.
|
|
|
|
The application can use general event probes to intercept the QoS
|
|
event and implement custom application specific QoS handling.</doc>

The seek event configures playback of the pipeline between @start to @stop

|
The @start and @stop values are expressed in @format.
|
|

A @rate of 1.0 means normal playback rate, 2.0 means double speed.

Negatives values means backwards playback. A value of 0.0 for the

rate is not allowed and should be accomplished instead by PAUSING the

|
|
|
|
A pipeline has a default playback segment configured with a start

|
position of 0, a stop position of -1 and a rate of 1.0. The currently

|
configured playback segment can be queried with #GST_QUERY_SEGMENT.
|
|
|
|
@start_type and @stop_type specify how to adjust the currently configured
|
|
start and stop fields in playback segment. Adjustments can be made relative
|
|
or absolute to the last configured values. A type of #GST_SEEK_TYPE_NONE
|
|
means that the position should not be updated.
|
|
|
|
When the rate is positive and @start has been updated, playback will start
|
|
from the newly configured start position.
|
|
|
|
For negative rates, playback will start from the newly configured stop

|
|
downstream synchronized with the buffer flow and contains timing information
|
|
and playback properties for the buffers that will follow.
|
|
|
|
The segment event marks the range of buffers to be processed. All
|
|
data not within the segment range is not to be processed. This can be
|
|
used intelligently by plugins to apply more efficient methods of skipping
|
|
unneeded data. The valid range is expressed with the @start and @stop
|
|
values.
|
|
|
|
The time value of the segment is used in conjunction with the start
|
|
value to convert the buffer timestamps into the stream time. This is
|
|
usually done in sinks to report the current stream_time.
|
|
@time represents the stream_time of a buffer carrying a timestamp of
|
|
@start. @time cannot be -1.
|
|
|
|
@start cannot be -1, @stop can be -1. If there
|
|
is a valid @stop given, it must be greater or equal the @start, including
|
|
when the indicated playback @rate is < 0.
|
|
|
|
The @applied_rate value provides information about any rate adjustment that
|
|
has already been made to the timestamps and content on the buffers of the
|
|
stream. (@rate * @applied_rate) should always equal the rate that has been
|
|
requested for playback. For example, if an element has an input segment
|
|
with intended playback @rate of 2.0 and applied_rate of 1.0, it can adjust
|
|
incoming timestamps and buffer content by half and output a segment event
|
|
with @rate of 1.0 and @applied_rate of 2.0
|
|
|
|
After a segment event, the buffer stream time is calculated with:
|
|

time + (TIMESTAMP(buf) - start) * ABS (rate * applied_rate)</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstghostpad.c">GhostPads are useful when organizing pipelines with #GstBin like elements.
|
|
The idea here is to create hierarchical element graphs. The bin element
|
|
contains a sub-graph. Now one would like to treat the bin-element like any
|
|
other #GstElement. This is where GhostPads come into play. A GhostPad acts as
|
|
a proxy for another pad. Thus the bin can have sink and source ghost-pads
|
|
that are associated with sink and source pads of the child elements.
|
|
|
|
If the target pad is known at creation time, gst_ghost_pad_new() is the
|
|
function to use to get a ghost-pad. Otherwise one can use gst_ghost_pad_new_no_target()
|
|
to create the ghost-pad and use gst_ghost_pad_set_target() to establish the
|
|
association later on.
|
|
|
|
Note that GhostPads add overhead to the data processing of a pipeline.</doc>

|
|
a threadsafe way.
|
|
|
|
Various GStreamer objects provide access to their internal structures using
|
|
an iterator.
|
|
|
|
Note that if calling a GstIterator function results in your code receiving
|
|
a refcounted object (with, say, g_value_get_object()), the refcount for that
|
|
object will not be increased. Your code is responsible for taking a reference
|
|
if it wants to continue using it later.
|
|
|
|
The basic use pattern of an iterator is as follows:
|
|
|[<!-- language="C" -->
|
|
GstIterator *it = _get_iterator(object);
|
|
GValue item = G_VALUE_INIT;
|
|
done = FALSE;

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstmemory.c">GstMemory is a lightweight refcounted object that wraps a region of memory.
|
|
They are typically used to manage the data of a #GstBuffer.
|
|
|
|
A GstMemory object has an allocated region of memory of maxsize. The maximum
|
|
size does not change during the lifetime of the memory object. The memory
|
|
also has an offset and size property that specifies the valid range of memory
|
|
in the allocated region.
|
|
|
|
Memory is usually created by allocators with a gst_allocator_alloc()
|
|
method call. When %NULL is used as the allocator, the default allocator will
|
|
be used.
|
|
|
|
New allocators can be registered with gst_allocator_register().
|
|
Allocators are identified by name and can be retrieved with
|
|
gst_allocator_find(). gst_allocator_set_default() can be used to change the
|
|
default allocator.
|
|
|
|
New memory can be created with gst_memory_new_wrapped() that wraps the memory
|
|
allocated elsewhere.
|
|
|
|
Refcounting of the memory block is performed with gst_memory_ref() and
|
|
gst_memory_unref().
|
|
|
|
The size of the memory can be retrieved and changed with
|
|
gst_memory_get_sizes() and gst_memory_resize() respectively.
|
|
|
|
Getting access to the data of the memory is performed with gst_memory_map().
|
|
The call will return a pointer to offset bytes into the region of memory.
|
|
After the memory access is completed, gst_memory_unmap() should be called.
|
|
|
|
Memory can be copied with gst_memory_copy(), which will return a writable
|
|
copy. gst_memory_share() will create a new memory block that shares the
|
|
memory with an existing memory block at a custom offset and with a custom
|
|
size.
|
|
|
|
Memory can be efficiently merged when gst_memory_is_span() returns %TRUE.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstmessage.c">Creates a new redirect message and adds a new entry to it. Redirect messages
|
|
are posted when an element detects that the actual data has to be retrieved
|
|
from a different location. This is useful if such a redirection cannot be
|
|
handled inside a source element, for example when HTTP 302/303 redirects
|
|
return a non-HTTP URL.
|
|
|
|
The redirect message can hold multiple entries. The first one is added
|
|
when the redirect message is created, with the given location, tag_list,
|
|
entry_struct arguments. Use gst_message_add_redirect_entry() to add more
|
|
entries.
|
|
|
|
Each entry has a location, a tag list, and a structure. All of these are
|
|
optional. The tag list and structure are useful for additional metadata,
|
|
such as bitrate statistics for the given location.
|
|
|
|
By default, message recipients should treat entries in the order they are
|
|
stored. The recipient should therefore try entry \#0 first, and if this
|
|
entry is not acceptable or working, try entry \#1 etc. Senders must make
|
|
sure that they add entries in this order. However, recipients are free to
|
|
ignore the order and pick an entry that is "best" for them. One example
|
|
would be a recipient that scans the entries for the one with the highest
|
|
bitrate tag.
|
|
|
|
The specified location string is copied. However, ownership over the tag
|
|
list and structure are transferred to the message.</doc>

metadata structure. The structure defines the API of the metadata and should

A metadata API is registered with gst_meta_api_type_register() which takes a

With gst_meta_api_type_has_tag() one can check if a certain metadata API

Multiple implementations of a metadata API can be registered.

To implement a metadata API, gst_meta_register() should be used. This

along with the size of the metadata. The function returns a #GstMetaInfo

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstminiobject.c">#GstMiniObject is a simple structure that can be used to implement refcounted
|
|
types.
|
|
|
|
Subclasses will include #GstMiniObject as the first member in their structure
|
|
and then call gst_mini_object_init() to initialize the #GstMiniObject fields.
|
|
|
|
gst_mini_object_ref() and gst_mini_object_unref() increment and decrement the
|
|
refcount respectively. When the refcount of a mini-object reaches 0, the
|
|
dispose function is called first and when this returns %TRUE, the free
|
|
function of the miniobject is called.
|
|
|
|
A copy can be made with gst_mini_object_copy().
|
|
|
|
gst_mini_object_is_writable() will return %TRUE when the refcount of the
|
|
object is exactly 1 and there is no parent or a single parent exists and is
|
|
writable itself, meaning the current caller has the only reference to the
|
|
object. gst_mini_object_make_writable() will return a writable version of
|
|
the object, which might be a new copy when the refcount was not 1.
|
|
|
|
Opaque data can be associated with a #GstMiniObject with
|
|
gst_mini_object_set_qdata() and gst_mini_object_get_qdata(). The data is
|
|
meant to be specific to the particular object and is not automatically copied
|
|
with gst_mini_object_copy() or similar methods.
|
|
|
|
A weak reference can be added and remove with gst_mini_object_weak_ref()
|
|
and gst_mini_object_weak_unref() respectively.</doc>

|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstobject.c">#GstObject provides a root for the object hierarchy tree filed in by the
|
|
GStreamer library. It is currently a thin wrapper on top of
|
|
#GInitiallyUnowned. It is an abstract class that is not very usable on its own.
|
|
|
|
#GstObject gives us basic refcounting, parenting functionality and locking.
|
|
Most of the functions are just extended for special GStreamer needs and can be
|
|
found under the same name in the base class of #GstObject which is #GObject
|
|
(e.g. g_object_ref() becomes gst_object_ref()).
|
|
|
|
Since #GstObject derives from #GInitiallyUnowned, it also inherits the
|
|
floating reference. Be aware that functions such as gst_bin_add() and
|
|
gst_element_add_pad() take ownership of the floating reference.
|
|
|
|
In contrast to #GObject instances, #GstObject adds a name property. The functions
|
|
gst_object_set_name() and gst_object_get_name() are used to set/get the name
|
|
of the object.
|
|
|
|
## controlled properties
|
|
|
|
Controlled properties offers a lightweight way to adjust gobject properties
|
|
over stream-time. It works by using time-stamped value pairs that are queued
|
|
for element-properties. At run-time the elements continuously pull value
|
|
changes for the current stream-time.
|
|
|
|
What needs to be changed in a #GstElement?
|
|
Very little - it is just two steps to make a plugin controllable!
|
|
|
|
* mark gobject-properties paramspecs that make sense to be controlled,
|
|
by GST_PARAM_CONTROLLABLE.
|
|
|
|
* when processing data (get, chain, loop function) at the beginning call
|
|
gst_object_sync_values(element,timestamp).
|
|
This will make the controller update all GObject properties that are
|
|
under its control with the current values based on the timestamp.
|
|
|
|
What needs to be done in applications? Again it's not a lot to change.
|
|
|
|
* create a #GstControlSource.
|
|
csource = gst_interpolation_control_source_new ();
|
|
g_object_set (csource, "mode", GST_INTERPOLATION_MODE_LINEAR, NULL);
|
|
|
|
* Attach the #GstControlSource on the controller to a property.
|
|
gst_object_add_control_binding (object, gst_direct_control_binding_new (object, "prop1", csource));
|
|
|
|
* Set the control values
|
|
gst_timed_value_control_source_set ((GstTimedValueControlSource *)csource,0 * GST_SECOND, value1);
|
|
gst_timed_value_control_source_set ((GstTimedValueControlSource *)csource,1 * GST_SECOND, value2);
|
|
|
|
* start your pipeline</doc>

|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpad.c">A #GstElement is linked to other elements via "pads", which are extremely
|
|
light-weight generic link points.
|
|
|
|
Pads have a #GstPadDirection, source pads produce data, sink pads consume
|
|
data.
|
|
|
|
Pads are typically created from a #GstPadTemplate with
|
|
gst_pad_new_from_template() and are then added to a #GstElement. This usually
|
|
happens when the element is created but it can also happen dynamically based
|
|
on the data that the element is processing or based on the pads that the
|
|
application requests.
|
|
|
|
Pads without pad templates can be created with gst_pad_new(),
|
|
which takes a direction and a name as an argument. If the name is %NULL,
|
|
then a guaranteed unique name will be assigned to it.
|
|
|
|
A #GstElement creating a pad will typically use the various
|
|
gst_pad_set_*_function\() calls to register callbacks for events, queries or
|
|
dataflow on the pads.
|
|
|
|
gst_pad_get_parent() will retrieve the #GstElement that owns the pad.
|
|
|
|
After two pads are retrieved from an element by gst_element_get_static_pad(),
|
|
the pads can be linked with gst_pad_link(). (For quick links,
|
|
you can also use gst_element_link(), which will make the obvious
|
|
link for you if it's straightforward.). Pads can be unlinked again with
|
|
gst_pad_unlink(). gst_pad_get_peer() can be used to check what the pad is
|
|
linked to.
|
|
|
|
Before dataflow is possible on the pads, they need to be activated with
|
|
gst_pad_set_active().
|
|
|
|
gst_pad_query() and gst_pad_peer_query() can be used to query various
|
|
properties of the pad and the stream.
|
|
|
|
To send a #GstEvent on a pad, use gst_pad_send_event() and
|
|
gst_pad_push_event(). Some events will be sticky on the pad, meaning that
|
|
after they pass on the pad they can be queried later with
|
|
gst_pad_get_sticky_event() and gst_pad_sticky_events_foreach().
|
|
gst_pad_get_current_caps() and gst_pad_has_current_caps() are convenience
|
|
functions to query the current sticky CAPS event on a pad.
|
|
|
|
GstElements will use gst_pad_push() and gst_pad_pull_range() to push out
|
|
or pull in a buffer.
|
|
|
|
The dataflow, events and queries that happen on a pad can be monitored with
|
|
probes that can be installed with gst_pad_add_probe(). gst_pad_is_blocked()
|
|
can be used to check if a block probe is installed on the pad.
|
|
gst_pad_is_blocking() checks if the blocking probe is currently blocking the
|
|
pad. gst_pad_remove_probe() is used to remove a previously installed probe
|
|
and unblock blocking probes if any.
|
|
|
|
Pad have an offset that can be retrieved with gst_pad_get_offset(). This
|
|
offset will be applied to the running_time of all data passing over the pad.
|
|
gst_pad_set_offset() can be used to change the offset.
|
|
|
|
Convenience functions exist to start, pause and stop the task on a pad with
|
|
gst_pad_start_task(), gst_pad_pause_task() and gst_pad_stop_task()
|
|
respectively.</doc>

|
|
by applications to send events in the pipeline.
|
|
|
|
If @pad is a source pad, @event should be an upstream event. If @pad is a
|
|
sink pad, @event should be a downstream event. For example, you would not
|
|
send a #GST_EVENT_EOS on a src pad; EOS events only propagate downstream.
|
|
Furthermore, some downstream events have to be serialized with data flow,
|
|
like EOS, while some can travel out-of-band, like #GST_EVENT_FLUSH_START. If
|
|
the event needs to be serialized with data flow, this function will take the
|
|
pad's stream lock while calling its event function.
|
|
|
|
To find out whether an event type is upstream, downstream, or downstream and
|
|
serialized, see #GstEventTypeFlags, gst_event_type_get_flags(),
|
|
#GST_EVENT_IS_UPSTREAM, #GST_EVENT_IS_DOWNSTREAM, and
|
|
#GST_EVENT_IS_SERIALIZED. Note that in practice that an application or
|
|
plugin doesn't need to bother itself with this information; the core handles
|
|
all necessary locks and checks.
|
|
|
|
This function takes ownership of the provided event so you should
|
|
gst_event_ref() it if you want to reuse the event after this call.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpad.h">This function will be called on source pads when a peer element
|
|
request a buffer at the specified @offset and @length. If this function
|
|
returns #GST_FLOW_OK, the result buffer will be stored in @buffer. The
|
|
contents of @buffer is invalid for any other return value.
|
|
|
|
This function is installed on a source pad with
|
|
gst_pad_set_getrange_function() and can only be called on source pads after
|
|
they are successfully activated with gst_pad_activate_mode() with the
|
|
#GST_PAD_MODE_PULL.
|
|
|
|
@offset and @length are always given in byte units. @offset must normally be a value
|
|
between 0 and the length in bytes of the data available on @pad. The
|
|
length (duration in bytes) can be retrieved with a #GST_QUERY_DURATION or with a
|
|
#GST_QUERY_SEEKING.
|
|
|
|
Any @offset larger or equal than the length will make the function return
|
|
#GST_FLOW_EOS, which corresponds to EOS. In this case @buffer does not
|
|
contain a valid buffer.
|
|
|
|
The buffer size of @buffer will only be smaller than @length when @offset is
|
|
near the end of the stream. In all other cases, the size of @buffer must be
|
|
exactly the requested size.
|
|
|
|
It is allowed to call this function with a 0 @length and valid @offset, in
|
|
which case @buffer will contain a 0-sized buffer and the function returns
|
|
#GST_FLOW_OK.
|
|
|
|
When this function is called with a -1 @offset, the sequentially next buffer
|
|
of length @length in the stream is returned.
|
|
|
|
When this function is called with a -1 @length, a buffer with a default
|
|
optimal length is returned in @buffer. The length might depend on the value
|
|
of @offset.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpadtemplate.c">Padtemplates describe the possible media types a pad or an elementfactory can
|
|
handle. This allows for both inspection of handled types before loading the
|
|
element plugin as well as identifying pads on elements that are not yet
|
|
created (request or sometimes pads).
|
|
|
|
Pad and PadTemplates have #GstCaps attached to it to describe the media type
|
|
they are capable of dealing with. gst_pad_template_get_caps() or
|
|
GST_PAD_TEMPLATE_CAPS() are used to get the caps of a padtemplate. It's not
|
|
possible to modify the caps of a padtemplate after creation.
|
|
|
|
PadTemplates have a #GstPadPresence property which identifies the lifetime
|
|
of the pad and that can be retrieved with GST_PAD_TEMPLATE_PRESENCE(). Also
|
|
the direction of the pad can be retrieved from the #GstPadTemplate with
|
|
GST_PAD_TEMPLATE_DIRECTION().
|
|
|
|
The GST_PAD_TEMPLATE_NAME_TEMPLATE () is important for GST_PAD_REQUEST pads
|
|
because it has to be used as the name in the gst_element_request_pad_simple()
|
|
call to instantiate a pad from this template.
|
|
|
|
Padtemplates can be created with gst_pad_template_new() or with
|
|
gst_static_pad_template_get (), which creates a #GstPadTemplate from a
|
|
#GstStaticPadTemplate that can be filled with the
|
|
convenient GST_STATIC_PAD_TEMPLATE() macro.
|
|
|
|
A padtemplate can be used to create a pad (see gst_pad_new_from_template()
|
|
or gst_pad_new_from_static_template ()) or to add to an element class
|
|
(see gst_element_class_add_static_pad_template ()).
|
|
|
|
The following code example shows the code to create a pad from a padtemplate.
|
|
|[<!-- language="C" -->
|
|
GstStaticPadTemplate my_template =
|
|
GST_STATIC_PAD_TEMPLATE (
|
|
"sink", // the name of the pad
|
|
GST_PAD_SINK, // the direction of the pad
|
|
GST_PAD_ALWAYS, // when this pad will be present
|
|
GST_STATIC_CAPS ( // the capabilities of the padtemplate
|
|
"audio/x-raw, "
|
|
"channels = (int) [ 1, 6 ]"
|
|
)
|
|
);
|
|
void
|
|
my_method (void)
|
|
{
|
|
GstPad *pad;
|
|
pad = gst_pad_new_from_static_template (&my_template, "sink");
|
|
...
|
|
}
|
|
]|
|
|
|
|
The following example shows you how to add the padtemplate to an
|
|
element class, this is usually done in the class_init of the class:
|
|
|[<!-- language="C" -->
|
|
static void
|
|
my_element_class_init (GstMyElementClass *klass)
|
|
{
|
|
GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
|
|
|

gst_element_class_add_static_pad_template (gstelement_class, &my_template);

|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpipeline.c">A #GstPipeline is a special #GstBin used as the toplevel container for
|
|
the filter graph. The #GstPipeline will manage the selection and
|
|
distribution of a global #GstClock as well as provide a #GstBus to the
|
|
application.
|
|
|
|
gst_pipeline_new() is used to create a pipeline. when you are done with
|
|
the pipeline, use gst_object_unref() to free its resources including all
|
|
added #GstElement objects (if not otherwise referenced).
|
|
|
|
Elements are added and removed from the pipeline using the #GstBin
|
|
methods like gst_bin_add() and gst_bin_remove() (see #GstBin).
|
|
|
|
Before changing the state of the #GstPipeline (see #GstElement) a #GstBus
|
|
should be retrieved with gst_pipeline_get_bus(). This #GstBus should then
|
|
be used to receive #GstMessage from the elements in the pipeline. Listening
|
|
to the #GstBus is necessary for retrieving error messages from the
|
|
#GstPipeline and otherwise the #GstPipeline might stop without any
|
|
indication, why. Furthermore, the #GstPipeline posts messages even if
|
|
nobody listens on the #GstBus, which will pile up and use up memory.
|
|
|
|
By default, a #GstPipeline will automatically flush the pending #GstBus
|
|
messages when going to the NULL state to ensure that no circular
|
|
references exist when no messages are read from the #GstBus. This
|
|
behaviour can be changed with gst_pipeline_set_auto_flush_bus().
|
|
|
|
When the #GstPipeline performs the PAUSED to PLAYING state change it will
|
|
select a clock for the elements. The clock selection algorithm will by
|
|
default select a clock provided by an element that is most upstream
|
|
(closest to the source). For live pipelines (ones that return
|
|
#GST_STATE_CHANGE_NO_PREROLL from the gst_element_set_state() call) this
|
|
will select the clock provided by the live source. For normal pipelines
|
|
this will select a clock provided by the sinks (most likely the audio
|
|
sink). If no element provides a clock, a default #GstSystemClock is used.
|
|
|
|
The clock selection can be controlled with the gst_pipeline_use_clock()
|
|
method, which will enforce a given clock on the pipeline. With
|
|
gst_pipeline_auto_clock() the default clock selection algorithm can be
|
|
restored.
|
|
|
|
A #GstPipeline maintains a running time for the elements. The running
|
|
time is defined as the difference between the current clock time and
|
|
the base time. When the pipeline goes to READY or a flushing seek is
|
|
performed on it, the running time is reset to 0. When the pipeline is
|
|
set from PLAYING to PAUSED, the current clock time is sampled and used to
|
|
configure the base time for the elements when the pipeline is set
|
|
to PLAYING again. The effect is that the running time (as the difference
|
|
between the clock time and the base time) will count how much time was spent
|
|
in the PLAYING state. This default behaviour can be changed with the
|
|
gst_element_set_start_time() method.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstplugin.c">GStreamer is extensible, so #GstElement instances can be loaded at runtime.
|
|
A plugin system can provide one or more of the basic GStreamer
|
|
#GstPluginFeature subclasses.
|
|
|
|
A plugin should export a symbol `gst_plugin_desc` that is a
|
|
struct of type #GstPluginDesc.
|
|
the plugin loader will check the version of the core library the plugin was
|
|
linked against and will create a new #GstPlugin. It will then call the
|
|
#GstPluginInitFunc function that was provided in the
|
|
`gst_plugin_desc`.
|
|
|
|
Once you have a handle to a #GstPlugin (e.g. from the #GstRegistry), you
|
|
can add any object that subclasses #GstPluginFeature.
|
|
|
|
Usually plugins are always automatically loaded so you don't need to call
|
|
gst_plugin_load() explicitly to bring it into memory. There are options to
|
|
statically link plugins to an app or even use GStreamer without a plugin
|
|
repository in which case gst_plugin_load() can be needed to bring the plugin

into memory.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpoll.c">A #GstPoll keeps track of file descriptors much like fd_set (used with
|
|
select ()) or a struct pollfd array (used with poll ()). Once created with
|
|
gst_poll_new(), the set can be used to wait for file descriptors to be
|
|
readable and/or writable. It is possible to make this wait be controlled
|
|
by specifying %TRUE for the @controllable flag when creating the set (or
|
|
later calling gst_poll_set_controllable()).
|
|
|
|
New file descriptors are added to the set using gst_poll_add_fd(), and
|
|
removed using gst_poll_remove_fd(). Controlling which file descriptors
|
|
should be waited for to become readable and/or writable are done using
|
|
gst_poll_fd_ctl_read(), gst_poll_fd_ctl_write() and gst_poll_fd_ctl_pri().
|
|
|
|
Use gst_poll_wait() to wait for the file descriptors to actually become
|
|
readable and/or writable, or to timeout if no file descriptor is available
|
|
in time. The wait can be controlled by calling gst_poll_restart() and
|
|
gst_poll_set_flushing().
|
|
|
|
Once the file descriptor set has been waited for, one can use
|
|
gst_poll_fd_has_closed() to see if the file descriptor has been closed,
|
|
gst_poll_fd_has_error() to see if it has generated an error,
|

gst_poll_fd_can_read() to see if it is possible to read from the file

descriptor, and gst_poll_fd_can_write() to see if it is possible to

|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpreset.c">This interface offers methods to query and manipulate parameter preset sets.
|
|
A preset is a bunch of property settings, together with meta data and a name.
|
|
The name of a preset serves as key for subsequent method calls to manipulate
|
|
single presets.
|
|
All instances of one type will share the list of presets. The list is created
|
|
on demand, if presets are not used, the list is not created.
|
|
|
|
The interface comes with a default implementation that serves most plugins.
|
|
Wrapper plugins will override most methods to implement support for the
|
|
native preset format of those wrapped plugins.
|
|
One method that is useful to be overridden is gst_preset_get_property_names().
|
|
With that one can control which properties are saved and in which order.
|
|
When implementing support for read-only presets, one should set the vmethods
|
|
for gst_preset_save_preset() and gst_preset_delete_preset() to %NULL.
|
|
Applications can use gst_preset_is_editable() to check for that.
|
|
|
|
The default implementation supports presets located in a system directory,
|
|
application specific directory and in the users home directory. When getting
|
|
a list of presets individual presets are read and overlaid in 1) system,
|
|
2) application and 3) user order. Whenever an earlier entry is newer, the
|
|
later entries will be updated. Since 1.8 you can also provide extra paths
|
|
where to find presets through the GST_PRESET_PATH environment variable.
|
|
Presets found in those paths will be considered as "app presets".</doc>

|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstpromise.c">The #GstPromise object implements the container for values that may
|
|
be available later. i.e. a Future or a Promise in
|
|
<https://en.wikipedia.org/wiki/Futures_and_promises>.
|
|
As with all Future/Promise-like functionality, there is the concept of the
|
|
producer of the value and the consumer of the value.
|
|
|
|
A #GstPromise is created with gst_promise_new() by the consumer and passed
|
|
to the producer to avoid thread safety issues with the change callback.
|
|
A #GstPromise can be replied to with a value (or an error) by the producer
|
|
with gst_promise_reply(). The exact value returned is defined by the API
|
|
contract of the producer and %NULL may be a valid reply.
|
|
gst_promise_interrupt() is for the consumer to
|
|
indicate to the producer that the value is not needed anymore and producing
|
|
that value can stop. The @GST_PROMISE_RESULT_EXPIRED state set by a call
|
|
to gst_promise_expire() indicates to the consumer that a value will never
|
|
be produced and is intended to be called by a third party that implements
|
|
some notion of message handling such as #GstBus.
|
|
A callback can also be installed at #GstPromise creation for
|
|
result changes with gst_promise_new_with_change_func().
|
|
The change callback can be used to chain #GstPromises's together as in the
|
|
following example.
|
|
|[<!-- language="C" -->
|
|
const GstStructure *reply;
|
|
GstPromise *p;
|
|
if (gst_promise_wait (promise) != GST_PROMISE_RESULT_REPLIED)
|
|
return; // interrupted or expired value
|
|
reply = gst_promise_get_reply (promise);
|
|
if (error in reply)
|
|
return; // propagate error
|
|
p = gst_promise_new_with_change_func (another_promise_change_func, user_data, notify);
|
|
pass p to promise-using API
|
|
]|
|
|
|
|
Each #GstPromise starts out with a #GstPromiseResult of
|
|
%GST_PROMISE_RESULT_PENDING and only ever transitions once
|
|
into one of the other #GstPromiseResult's.
|
|
|
|
In order to support multi-threaded code, gst_promise_reply(),
|
|
gst_promise_interrupt() and gst_promise_expire() may all be from
|
|
different threads with some restrictions and the final result of the promise
|
|
is whichever call is made first. There are two restrictions on ordering:
|
|
|
|
1. That gst_promise_reply() and gst_promise_interrupt() cannot be called
|
|
after gst_promise_expire()
|
|
2. That gst_promise_reply() and gst_promise_interrupt()
|
|
cannot be called twice.
|
|
|
|
The change function set with gst_promise_new_with_change_func() is

|
The CAPS query should return the allowable caps for a pad in the context
|
|
of the element's state, its link to other elements, and the devices or files
|
|
it has opened. These caps must be a subset of the pad template caps. In the
|
|
NULL state with no links, the CAPS query should ideally return the same caps
|
|
as the pad template. In rare circumstances, an object property can affect
|
|
the caps returned by the CAPS query, but this is discouraged.
|
|
|
|
For most filters, the caps returned by CAPS query is directly affected by the
|
|
allowed caps on other pads. For demuxers and decoders, the caps returned by
|
|
the srcpad's getcaps function is directly related to the stream data. Again,
|
|
the CAPS query should return the most specific caps it reasonably can, since this
|
|
helps with autoplugging.
|
|
|
|
The @filter is used to restrict the result caps, only the caps matching
|
|
@filter should be returned from the CAPS query. Specifying a filter might
|
|
greatly reduce the amount of processing an element needs to do.

<emphasis role="bold">Design:</emphasis>
|
|
|
|
The #GstRegistry object is a list of plugins and some functions for dealing
|
|
with them. Each #GstPlugin is matched 1-1 with a file on disk, and may or may
|
|
not be loaded at a given time.
|
|
|
|
The primary source, at all times, of plugin information is each plugin file
|
|
itself. Thus, if an application wants information about a particular plugin,
|
|
or wants to search for a feature that satisfies given criteria, the primary
|
|
means of doing so is to load every plugin and look at the resulting
|
|
information that is gathered in the default registry. Clearly, this is a time
|
|
consuming process, so we cache information in the registry file. The format
|
|
and location of the cache file is internal to gstreamer.
|
|
|
|
On startup, plugins are searched for in the plugin search path. The following
|
|
locations are checked in this order:
|
|
|
|
* location from --gst-plugin-path commandline option.
|
|
* the GST_PLUGIN_PATH environment variable.
|
|
* the GST_PLUGIN_SYSTEM_PATH environment variable.
|
|
* default locations (if GST_PLUGIN_SYSTEM_PATH is not set).
|
|
Those default locations are:
|
|
`$XDG_DATA_HOME/gstreamer-$GST_API_VERSION/plugins/`
|
|
and `$prefix/libs/gstreamer-$GST_API_VERSION/`.
|
|
[$XDG_DATA_HOME](http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) defaults to
|
|
`$HOME/.local/share`.
|
|
|
|
The registry cache file is loaded from
|
|
`$XDG_CACHE_HOME/gstreamer-$GST_API_VERSION/registry-$ARCH.bin`
|
|
(where $XDG_CACHE_HOME defaults to `$HOME/.cache`) or the file listed in the `GST_REGISTRY`
|
|
env var. One reason to change the registry location is for testing.
|
|
|
|
For each plugin that is found in the plugin search path, there could be 3
|
|
possibilities for cached information:
|
|
|
|
* the cache may not contain information about a given file.
|
|
* the cache may have stale information.
|
|
* the cache may have current information.
|
|
|
|
In the first two cases, the plugin is loaded and the cache updated. In
|
|
addition to these cases, the cache may have entries for plugins that are not
|
|
relevant to the current process. These are marked as not available to the
|
|
current process. If the cache is updated for whatever reason, it is marked
|
|
dirty.
|
|
|
|
A dirty cache is written out at the end of initialization. Each entry is
|
|
checked to make sure the information is minimally valid. If not, the entry is
|
|
simply dropped.
|
|
|
|
## Implementation notes:
|
|
|
|
The "cache" and "registry" are different concepts and can represent
|
|
different sets of plugins. For various reasons, at init time, the cache is
|
|
stored in the default registry, and plugins not relevant to the current
|
|
process are marked with the %GST_PLUGIN_FLAG_CACHED bit. These plugins are
|
|
removed at the end of initialization.</doc>

|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstsegment.h">Flags to be used with gst_element_seek() or gst_event_new_seek(). All flags
|
|
can be used together.
|
|
|
|
A non flushing seek might take some time to perform as the currently
|
|
playing data in the pipeline will not be cleared.
|
|
|
|
An accurate seek might be slower for formats that don't have any indexes
|
|
or timestamp markers in the stream. Specifying this flag might require a
|
|
complete scan of the file in those cases.
|
|
|
|
When performing a segment seek: after the playback of the segment completes,
|
|
no EOS will be emitted by the element that performed the seek, but a
|
|
%GST_MESSAGE_SEGMENT_DONE message will be posted on the bus by the element.
|
|
When this message is posted, it is possible to send a new seek event to
|
|
continue playback. With this seek method it is possible to perform seamless
|
|
looping or simple linear editing.
|
|
|
|
When only changing the playback rate and not the direction, the
|
|
%GST_SEEK_FLAG_INSTANT_RATE_CHANGE flag can be used for a non-flushing seek
|
|
to signal that the rate change should be applied immediately. This requires
|
|
special support in the seek handlers (e.g. demuxers) and any elements
|
|
synchronizing to the clock, and in general can't work in all cases (for example
|
|
UDP streaming where the delivery rate is controlled by a remote server). The
|
|
instant-rate-change mode supports changing the trickmode-related GST_SEEK_ flags,
|
|
but can't be used in conjunction with other seek flags that affect the new
|
|
playback position - as the playback position will not be changing.
|
|
|
|
When doing fast forward (rate > 1.0) or fast reverse (rate < -1.0) trickmode
|
|
playback, the %GST_SEEK_FLAG_TRICKMODE flag can be used to instruct decoders
|
|
and demuxers to adjust the playback rate by skipping frames. This can improve
|
|
performance and decrease CPU usage because not all frames need to be decoded.
|
|
|
|
Beyond that, the %GST_SEEK_FLAG_TRICKMODE_KEY_UNITS flag can be used to
|
|
request that decoders skip all frames except key units, and
|
|
%GST_SEEK_FLAG_TRICKMODE_NO_AUDIO flags can be used to request that audio
|
|
decoders do no decoding at all, and simple output silence.
|
|
|
|
The %GST_SEEK_FLAG_SNAP_BEFORE flag can be used to snap to the previous
|
|
relevant location, and the %GST_SEEK_FLAG_SNAP_AFTER flag can be used to
|
|
select the next relevant location. If %GST_SEEK_FLAG_KEY_UNIT is specified,
|
|
the relevant location is a keyframe. If both flags are specified, the nearest
|
|
of these locations will be selected. If none are specified, the implementation is
|
|
free to select whichever it wants.
|
|
|
|
The before and after here are in running time, so when playing backwards,
|
|
the next location refers to the one that will played in next, and not the
|
|
one that is located after in the actual source stream.
|
|
|
|
Also see part-seeking.txt in the GStreamer design documentation for more
|
|
details on the meaning of these flags and the behaviour expected of
|
|
elements that handle them.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstsegment.c">This helper structure holds the relevant values for tracking the region of
|
|
interest in a media file, called a segment.
|
|
|
|
The structure can be used for two purposes:
|
|
|
|
* performing seeks (handling seek events)
|
|
* tracking playback regions (handling newsegment events)
|
|
|
|
The segment is usually configured by the application with a seek event which
|
|
is propagated upstream and eventually handled by an element that performs the seek.
|
|
|
|
The configured segment is then propagated back downstream with a newsegment event.
|
|
This information is then used to clip media to the segment boundaries.
|
|
|
|
A segment structure is initialized with gst_segment_init(), which takes a #GstFormat
|
|
that will be used as the format of the segment values. The segment will be configured
|
|
with a start value of 0 and a stop/duration of -1, which is undefined. The default
|
|
rate and applied_rate is 1.0.
|
|
|
|
The public duration field contains the duration of the segment. When using
|
|
the segment for seeking, the start and time members should normally be left
|
|
to their default 0 value. The stop position is left to -1 unless explicitly
|
|
configured to a different value after a seek event.
|
|
|
|
The current position in the segment should be set by changing the position
|
|
member in the structure.
|
|
|
|
For elements that perform seeks, the current segment should be updated with the
|
|
gst_segment_do_seek() and the values from the seek event. This method will update
|
|
all the segment fields. The position field will contain the new playback position.
|
|
If the start_type was different from GST_SEEK_TYPE_NONE, playback continues from
|
|
the position position, possibly with updated flags or rate.
|
|
|
|
For elements that want to use #GstSegment to track the playback region,
|
|
update the segment fields with the information from the newsegment event.
|
|
The gst_segment_clip() method can be used to check and clip
|
|
the media data to the segment boundaries.
|
|
|
|
For elements that want to synchronize to the pipeline clock, gst_segment_to_running_time()
|
|
can be used to convert a timestamp to a value that can be used to synchronize
|
|
to the clock. This function takes into account the base as well as
|
|
any rate or applied_rate conversions.
|
|
|
|
For elements that need to perform operations on media data in stream_time,
|
|
gst_segment_to_stream_time() can be used to convert a timestamp and the segment
|
|
info to stream time (which is always between 0 and the duration of the stream).</doc>

The applied rate can be set by source elements when a server is

sending the stream with an already modified playback speed
|
|
rate. Filter elements that modify the stream in a way that
|
|
modifies the playback speed should also modify the applied

rate. For example the #videorate element when its

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gststructure.c">A #GstStructure is a collection of key/value pairs. The keys are expressed as
|
|
GQuarks and the values can be of any GType.
|
|
|
|
In addition to the key/value pairs, a #GstStructure also has a name. The name
|
|
starts with a letter and can be filled by letters, numbers and any of
|
|
"/-_.:".
|
|
|
|
#GstStructure is used by various GStreamer subsystems to store information in
|
|
a flexible and extensible way. A #GstStructure does not have a refcount
|
|
because it usually is part of a higher level object such as #GstCaps,
|
|
#GstMessage, #GstEvent, #GstQuery. It provides a means to enforce mutability
|
|
using the refcount of the parent with the gst_structure_set_parent_refcount()
|
|
method.
|
|
|
|
A #GstStructure can be created with gst_structure_new_empty() or
|
|
gst_structure_new(), which both take a name and an optional set of key/value
|
|
pairs along with the types of the values.
|
|
|
|
Field values can be changed with gst_structure_set_value() or
|
|
gst_structure_set().
|
|
|
|
Field values can be retrieved with gst_structure_get_value() or the more
|
|
convenient gst_structure_get_*() functions.
|
|
|
|
Fields can be removed with gst_structure_remove_field() or
|
|
gst_structure_remove_fields().
|
|
|
|
Strings in structures must be ASCII or UTF-8 encoded. Other encodings are not
|
|
allowed. Strings may be %NULL however.
|
|
|
|
## The serialization format
|
|
|
|
GstStructure serialization format serialize the GstStructure name,
|
|
keys/GType/values in a comma separated list with the structure name as first
|
|
field without value followed by separated key/value pairs in the form
|
|
`key=value`, for example:
|
|
|
|
```
|
|
a-structure, key=value
|
|
````
|
|
|
|
The values type will be inferred if not explicitly specified with the
|
|
`(GTypeName)value` syntax, for example the following struct will have one
|
|
field called 'is-string' which has the string 'true' as a value:
|
|
|
|
```
|
|
a-struct, field-is-string=(string)true, field-is-boolean=true
|
|
```
|
|
|
|
*Note*: without specifying `(string), `field-is-string` type would have been
|
|
inferred as boolean.
|
|
|
|
*Note*: we specified `(string)` as a type even if `gchararray` is the actual
|
|
GType name as for convenience some well known types have been aliased or
|
|
abbreviated.
|
|
|
|
To avoid specifying the type, you can give some hints to the "type system".
|
|
For example to specify a value as a double, you should add a decimal (ie. `1`
|
|
is an `int` while `1.0` is a `double`).
|
|
|
|
*Note*: when a structure is serialized with #gst_structure_to_string, all
|
|
values are explicitly typed.
|
|
|
|
Some types have special delimiters:
|
|
|
|
- [GstValueArray](GST_TYPE_ARRAY) are inside curly brackets (`{` and `}`).
|
|
For example `a-structure, array={1, 2, 3}`
|
|
- Ranges are inside brackets (`[` and `]`). For example `a-structure,
|
|
range=[1, 6, 2]` 1 being the min value, 6 the maximum and 2 the step. To
|
|
specify a #GST_TYPE_INT64_RANGE you need to explicitly specify it like:
|
|
`a-structure, a-int64-range=(gint64) [1, 5]`
|
|
- [GstValueList](GST_TYPE_LIST) are inside "less and greater than" (`<` and
|
|
`>`). For example `a-structure, list=<1, 2, 3>
|
|
|
|
Structures are delimited either by a null character `\0` or a semicolon `;`
|
|
the latter allowing to store multiple structures in the same string (see
|
|
#GstCaps).
|
|
|
|
Quotes are used as "default" delimiters and can be used around any types that
|
|
don't use other delimiters (for example `a-struct, i=(int)"1"`). They are use
|
|
to allow adding spaces or special characters (such as delimiters,
|
|
semicolumns, etc..) inside strings and you can use backslashes `\` to escape
|
|
characters inside them, for example:
|
|
|
|
```
|
|
a-struct, special="\"{[(;)]}\" can be used inside quotes"
|
|
```
|
|
|
|
They also allow for nested structure, such as:
|
|
|
|
```
|
|
a-struct, nested=(GstStructure)"nested-struct, nested=true"
|
|
```
|
|
|
|
Since 1.20, nested structures and caps can be specified using brackets (`[`
|
|
and `]`), for example:
|
|
|
|
```
|
|
a-struct, nested=[nested-struct, nested=true]
|
|
```

|

Variable arguments should be in the form field id quark, field type

The last variable argument should be %NULL (technically it should be a

the %NULL terminator and warn if it's not there).

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gsttagsetter.c">Element interface that allows setting of media metadata.
|
|
|
|
Elements that support changing a stream's metadata will implement this
|
|
interface. Examples of such elements are 'vorbisenc', 'theoraenc' and
|
|
'id3v2mux'.
|
|
|
|
If you just want to retrieve metadata in your application then all you
|
|
need to do is watch for tag messages on your pipeline's bus. This
|
|
interface is only for setting metadata, not for extracting it. To set tags
|
|
from the application, find tagsetter elements and set tags using e.g.
|
|
gst_tag_setter_merge_tags() or gst_tag_setter_add_tags(). Also consider
|
|
setting the #GstTagMergeMode that is used for tag events that arrive at the
|
|
tagsetter element (default mode is to keep existing tags).
|
|
The application should do that before the element goes to %GST_STATE_PAUSED.
|
|
|
|
Elements implementing the #GstTagSetter interface often have to merge
|
|
any tags received from upstream and the tags set by the application via
|
|
the interface. This can be done like this:
|
|
|
|
|[<!-- language="C" -->
|
|
GstTagMergeMode merge_mode;
|
|
const GstTagList *application_tags;
|
|
const GstTagList *event_tags;
|
|
GstTagSetter *tagsetter;
|
|
GstTagList *result;
|
|
|
|
tagsetter = GST_TAG_SETTER (element);
|
|
|
|
merge_mode = gst_tag_setter_get_tag_merge_mode (tagsetter);
|
|
application_tags = gst_tag_setter_get_tag_list (tagsetter);
|
|
event_tags = (const GstTagList *) element->event_tags;
|
|
|
|
GST_LOG_OBJECT (tagsetter, "merging tags, merge mode = %d", merge_mode);
|
|
GST_LOG_OBJECT (tagsetter, "event tags: %" GST_PTR_FORMAT, event_tags);
|
|
GST_LOG_OBJECT (tagsetter, "set tags: %" GST_PTR_FORMAT, application_tags);
|
|
|
|
result = gst_tag_list_merge (application_tags, event_tags, merge_mode);
|
|
|
|
GST_LOG_OBJECT (tagsetter, "final tags: %" GST_PTR_FORMAT, result);

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gsttask.c">#GstTask is used by #GstElement and #GstPad to provide the data passing
|
|
threads in a #GstPipeline.
|
|
|
|
A #GstPad will typically start a #GstTask to push or pull data to/from the
|
|
peer pads. Most source elements start a #GstTask to push data. In some cases
|
|
a demuxer element can start a #GstTask to pull data from a peer element. This
|
|
is typically done when the demuxer can perform random access on the upstream
|
|
peer element for improved performance.
|
|
|
|
Although convenience functions exist on #GstPad to start/pause/stop tasks, it
|
|
might sometimes be needed to create a #GstTask manually if it is not related to
|
|
a #GstPad.
|
|
|
|
Before the #GstTask can be run, it needs a #GRecMutex that can be set with
|
|
gst_task_set_lock().
|
|
|
|
The task can be started, paused and stopped with gst_task_start(), gst_task_pause()
|
|
and gst_task_stop() respectively or with the gst_task_set_state() function.
|
|
|
|
A #GstTask will repeatedly call the #GstTaskFunction with the user data
|
|
that was provided when creating the task with gst_task_new(). While calling
|
|
the function it will acquire the provided lock. The provided lock is released
|
|
when the task pauses or stops.

Stopping a task with gst_task_stop() will not immediately make sure the task is
|
|
not running anymore. Use gst_task_join() to make sure the task is completely
|
|
stopped and the thread is stopped.
|
|
|
|
After creating a #GstTask, use gst_object_unref() to free its resources. This can
|
|
only be done when the task is not running anymore.
|
|
|
|
Task functions can send a #GstMessage to send out-of-band data to the
|
|
application. The application can receive messages from the #GstBus in its
|
|
mainloop.
|
|
|
|
For debugging purposes, the task will configure its object name as the thread
|
|
name on Linux. Please note that the object name should be configured before the
|
|
task is started; changing the object name after the task has been started, has
|
|
no effect on the thread name.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gsttoc.c">#GstToc functions are used to create/free #GstToc and #GstTocEntry structures.
|
|
Also they are used to convert #GstToc into #GstStructure and vice versa.
|
|
|
|
#GstToc lets you to inform other elements in pipeline or application that playing
|
|
source has some kind of table of contents (TOC). These may be chapters, editions,
|
|
angles or other types. For example: DVD chapters, Matroska chapters or cue sheet
|
|
TOC. Such TOC will be useful for applications to display instead of just a
|
|
playlist.
|
|
|
|
Using TOC is very easy. Firstly, create #GstToc structure which represents root
|
|
contents of the source. You can also attach TOC-specific tags to it. Then fill
|
|
it with #GstTocEntry entries by appending them to the #GstToc using
|
|
gst_toc_append_entry(), and appending subentries to a #GstTocEntry using
|
|
gst_toc_entry_append_sub_entry().
|
|
|
|
Note that root level of the TOC can contain only either editions or chapters. You
|
|
should not mix them together at the same level. Otherwise you will get serialization
|
|
/deserialization errors. Make sure that no one of the entries has negative start and
|
|
stop values.
|
|
|
|
Use gst_event_new_toc() to create a new TOC #GstEvent, and gst_event_parse_toc() to
|
|
parse received TOC event. Use gst_event_new_toc_select() to create a new TOC select #GstEvent,
|
|
and gst_event_parse_toc_select() to parse received TOC select event. The same rule for
|
|
the #GstMessage: gst_message_new_toc() to create new TOC #GstMessage, and
|
|
gst_message_parse_toc() to parse received TOC message.
|
|
|
|
TOCs can have global scope or current scope. Global scope TOCs contain
|
|
all entries that can possibly be selected using a toc select event, and
|
|
are what an application is usually interested in. TOCs with current scope
|
|
only contain the parts of the TOC relevant to the currently selected/playing
|
|
stream; the current scope TOC is used by downstream elements such as muxers
|
|
to write correct TOC entries when transcoding files, for example. When
|
|
playing a DVD, the global TOC would contain a hierarchy of all titles,
|
|
chapters and angles, for example, while the current TOC would only contain
|
|
the chapters for the currently playing title if playback of a specific
|
|
title was requested.
|
|
|
|
Applications and plugins should not rely on TOCs having a certain kind of
|
|
structure, but should allow for different alternatives. For example, a
|
|
simple CUE sheet embedded in a file may be presented as a flat list of
|
|
track entries, or could have a top-level edition node (or some other
|
|
alternative type entry) with track entries underneath that node; or even
|
|
multiple top-level edition nodes (or some other alternative type entries)
|
|
each with track entries underneath, in case the source file has extracted
|
|
a track listing from different sources).</doc>

|
Elements that support some kind of chapters or editions (or tracks like in
|
|
the FLAC cue sheet) will implement this interface.
|
|
|
|
If you just want to retrieve the TOC in your application then all you
|
|
need to do is watch for TOC messages on your pipeline's bus (or you can
|
|
perform TOC query). This interface is only for setting TOC data, not for
|
|
extracting it. To set TOC from the application, find proper tocsetter element
|
|
and set TOC using gst_toc_setter_set_toc().
|
|
|
|
Elements implementing the #GstTocSetter interface can extend existing TOC
|
|
by getting extend UID for that (you can use gst_toc_find_entry() to retrieve it)
|
|
with any TOC entries received from downstream.</doc>

The @name without the ".class" suffix will be used for the log records.

There must be fields for each value that gets logged where the field name is

the value name. The field must be a #GstStructure describing the value. The

sub structure must contain a field called 'type' of %G_TYPE_GTYPE that

contains the GType of the value. The resulting #GstTracerRecord will take

ownership of the field structures.

The way to deal with optional values is to log an additional boolean before
|

the optional field, that if %TRUE signals that the optional field is valid
|
|
and %FALSE signals that the optional field should be ignored. One must still
|

log a placeholder value for the optional field though. Please also note, that

pointer type values must not be NULL - the underlying serialisation can not

Hash table returned by this API is a list of "key-value" pairs, and the each
|
|
pair is generated by splitting "URI fragment" per "&" sub-delims, then "key"
|
|
and "value" are split by "=" sub-delims. The "key" returned by this API may

be undefined keyword by standard.
|
|
A value may be %NULL to indicate that the key should appear in the fragment

string in the URI, but does not have a value. Free the returned #GHashTable

with #g_hash_table_unref() when it is no longer required.

Modifying this hash table does not affect the fragment in the URI.

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gsturi.c">Parses a URI string into a new #GstUri object. Will return NULL if the URI
|

cannot be parsed. This is identical to gst_uri_from_string() except that
|
|
the userinfo and fragment components of the URI will not be unescaped while
|
|
parsing.
|
|
|
|
Use this when you need to extract a username and password from the userinfo
|
|
such as https://user:password@example.com since either may contain
|
|
a URI-escaped ':' character. gst_uri_from_string() will unescape the entire
|
|
userinfo component, which will make it impossible to know which ':'
|
|
delineates the username and password.
|
|
|
|
The same applies to the fragment component of the URI, such as
|
|
https://example.com/path#fragment which may contain a URI-escaped '#'.</doc>

Any discrete (packetizable) media type is supported, with provisions for
|
|
automatically determining source type.
|
|
|
|
Formatting/framing information is provided with a powerful negotiation
|

framework.
|
|
|

|

|
|
GStreamer covers a wide range of use cases including: playback, recording,
|
|
editing, serving streams, voice over ip and video calls.
|
|
|
|
The `GStreamer` library should be initialized with
|
|
gst_init() before it can be used. You should pass pointers to the main `argc`
|
|
and `argv` variables so that GStreamer can process its own command line
|
|
options, as shown in the following example.
|
|
|
|
## Initializing the gstreamer library
|
|
|
|
``` C
|
|
int main (int argc, char *argv[])
|
|
{
|
|
// initialize the GStreamer library
|
|
gst_init (&argc, &argv);
|
|
...
|
|
}
|
|
```
|
|
|
|
It's allowed to pass two %NULL pointers to gst_init() in case you don't want
|
|
to pass the command line args to GStreamer.
|
|
|
|
You can also use #GOptionContext to initialize your own parameters as shown in
|
|
the next code fragment:
|
|
|
|
## Initializing own parameters when initializing GStreamer
|
|
|
|
``` C
|
|
static gboolean stats = FALSE;
|
|
...
|
|
int
|
|
main (int argc, char *argv[])
|
|
{
|
|
GOptionEntry options[] = {
|
|
{"tags", 't', 0, G_OPTION_ARG_NONE, &tags,
|
|
N_("Output tags (also known as metadata)"), NULL},
|
|
{NULL}
|
|
};
|
|
ctx = g_option_context_new ("[ADDITIONAL ARGUMENTS]");
|
|
g_option_context_add_main_entries (ctx, options, GETTEXT_PACKAGE);
|
|
g_option_context_add_group (ctx, gst_init_get_option_group ());
|
|
if (!g_option_context_parse (ctx, &argc, &argv, &err)) {
|
|
g_print ("Error initializing: %s\n", GST_STR_NULL (err->message));
|
|
exit (1);
|
|
}
|
|
g_option_context_free (ctx);
|
|
...
|
|
}
|
|
```
|
|
|
|
Use gst_version() to query the library version at runtime or use the
|
|
GST_VERSION_* macros to find the version at compile time. Optionally
|
|
gst_version_string() returns a printable string.
|
|
|
|
The gst_deinit() call is used to clean up all internal resources used
|
|
by GStreamer. It is mostly used in unit tests to check for leaks.</doc>

<docsection name="gsterror">
|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gsterror.c">GStreamer elements can throw non-fatal warnings and fatal errors.
|
|
Higher-level elements and applications can programmatically filter
|
|
the ones they are interested in or can recover from,
|
|
and have a default handler handle the rest of them.
|
|
|
|
The rest of this section will use the term "error"
|
|
to mean both (non-fatal) warnings and (fatal) errors; they are treated
|
|
similarly.
|
|
|
|
Errors from elements are the combination of a #GError and a debug string.
|
|
The #GError contains:
|
|
- a domain type: CORE, LIBRARY, RESOURCE or STREAM
|
|
- a code: an enum value specific to the domain
|
|
- a translated, human-readable message
|
|
- a non-translated additional debug string, which also contains
|
|
- file and line information
|
|
|
|
Elements do not have the context required to decide what to do with
|
|
errors. As such, they should only inform about errors, and stop their
|
|
processing. In short, an element doesn't know what it is being used for.
|
|
|
|
It is the application or compound element using the given element that
|
|
has more context about the use of the element. Errors can be received by
|
|
listening to the #GstBus of the element/pipeline for #GstMessage objects with
|
|
the type %GST_MESSAGE_ERROR or %GST_MESSAGE_WARNING. The thrown errors should
|
|
be inspected, and filtered if appropriate.
|
|
|
|
An application is expected to, by default, present the user with a
|
|
dialog box (or an equivalent) showing the error message. The dialog
|
|
should also allow a way to get at the additional debug information,
|
|
so the user can provide bug reporting information.
|
|
|
|
A compound element is expected to forward errors by default higher up
|
|
the hierarchy; this is done by default in the same way as for other types
|
|
of #GstMessage.
|
|
|
|
When applications or compound elements trigger errors that they can
|
|
recover from, they can filter out these errors and take appropriate action.
|
|
For example, an application that gets an error from xvimagesink
|
|
that indicates all XVideo ports are taken, the application can attempt
|
|
to use another sink instead.
|
|
|
|
Elements throw errors using the #GST_ELEMENT_ERROR convenience macro:
|
|
|
|
## Throwing an error
|
|
|
|
|[
|
|
GST_ELEMENT_ERROR (src, RESOURCE, NOT_FOUND,
|
|
(_("No file name specified for reading.")), (NULL));
|
|
]|
|
|
|
|
Things to keep in mind:
|
|
|
|
* Don't go off inventing new error codes. The ones
|
|
currently provided should be enough. If you find your type of error
|
|
does not fit the current codes, you should use FAILED.
|
|
* Don't provide a message if the default one suffices.
|
|
this keeps messages more uniform. Use (%NULL) - not forgetting the
|
|
parentheses.
|
|
* If you do supply a custom message, it should be
|
|
marked for translation. The message should start with a capital
|
|
and end with a period. The message should describe the error in short,
|
|
in a human-readable form, and without any complex technical terms.
|
|
A user interface will present this message as the first thing a user
|
|
sees. Details, technical info, ... should go in the debug string.
|
|
|
|
* The debug string can be as you like. Again, use (%NULL)
|
|
if there's nothing to add - file and line number will still be
|
|
passed. #GST_ERROR_SYSTEM can be used as a shortcut to give
|
|
debug information on a system call error.</doc>

<docsection name="gstinfo">
|
|
<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gstinfo.c">GStreamer's debugging subsystem is an easy way to get information about what
|
|
the application is doing. It is not meant for programming errors. Use GLib
|
|
methods (g_warning and friends) for that.
|
|
|
|
The debugging subsystem works only after GStreamer has been initialized
|
|
- for example by calling gst_init().
|
|
|
|
The debugging subsystem is used to log informational messages while the
|
|
application runs. Each messages has some properties attached to it. Among
|
|
these properties are the debugging category, the severity (called "level"
|
|
here) and an optional #GObject it belongs to. Each of these messages is sent
|
|
to all registered debugging handlers, which then handle the messages.
|
|
GStreamer attaches a default handler on startup, which outputs requested
|
|
messages to stderr.
|
|
|
|
Messages are output by using shortcut macros like #GST_DEBUG,
|
|
#GST_CAT_ERROR_OBJECT or similar. These all expand to calling gst_debug_log()
|
|
with the right parameters.
|
|
The only thing a developer will probably want to do is define his own
|
|
categories. This is easily done with 3 lines. At the top of your code,
|
|
declare
|
|
the variables and set the default category.
|
|
|[<!-- language="C" -->
|
|
GST_DEBUG_CATEGORY_STATIC (my_category); // define category (statically)
|
|
#define GST_CAT_DEFAULT my_category // set as default
|
|
]|
|
|
After that you only need to initialize the category.
|
|
|[<!-- language="C" -->
|
|
GST_DEBUG_CATEGORY_INIT (my_category, "my category",
|
|
0, "This is my very own");
|
|
]|
|
|
Initialization must be done before the category is used first.
|
|
Plugins do this
|
|
in their plugin_init function, libraries and applications should do that
|
|
during their initialization.
|
|
|
|
The whole debugging subsystem can be disabled at build time with passing the
|
|
--disable-gst-debug switch to configure. If this is done, every function,
|
|
macro and even structs described in this file evaluate to default values or
|
|
nothing at all.
|
|
So don't take addresses of these functions or use other tricks.
|
|
If you must do that for some reason, there is still an option.
|
|
If the debugging
|
|
subsystem was compiled out, GST_DISABLE_GST_DEBUG is defined in
|
|
<gst/gst.h>,
|
|
so you can check that before doing your trick.
|
|
Disabling the debugging subsystem will give you a slight (read: unnoticeable)
|
|
speed increase and will reduce the size of your compiled code. The GStreamer
|
|
library itself becomes around 10% smaller.
|
|
|
|
Please note that there are naming conventions for the names of debugging
|
|
categories. These are explained at GST_DEBUG_CATEGORY_INIT().</doc>

#GstBuffer to be attached to that buffer.

Typically, a demuxer element would attach GstProtectionMeta objects

to the buffers that it pushes downstream. The demuxer would parse the
|
|
protection information for a video/audio frame from its input data and use
|
|
this information to populate the #GstStructure @info field,
|
|
which is then encapsulated in a GstProtectionMeta object and attached to
|
|
the corresponding output buffer using the gst_buffer_add_protection_meta()
|
|
function. The information in this attached GstProtectionMeta would be

|
used by a downstream decrypter element to recover the original unencrypted

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gststreams.c">A #GstStream is a high-level object defining a stream of data which is, or

can be, present in a #GstPipeline.
|
|
|

It is defined by a unique identifier, a "Stream ID". A #GstStream does not
|
|
automatically imply the stream is present within a pipeline or element.
|
|
|
|
Any element that can introduce new streams in a pipeline should create the

appropriate #GstStream object, and can convey that object via the
|
|
%GST_EVENT_STREAM_START event and/or the #GstStreamCollection.
|
|
|

Elements that do not modify the nature of the stream can add extra information
|

on it (such as enrich the #GstCaps, or #GstTagList). This is typically done

by parsing elements.</doc>

<doc xml:space="preserve" filename="../subprojects/gstreamer/gst/gsttaglist.h">Returns a writable copy of @taglist.
|
|
|
|
If there is only one reference count on @taglist, the caller must be the
|
|
owner, and so this function will return the taglist object unchanged. If on
|
|
the other hand there is more than one reference on the object, a new taglist
|
|
object will be returned (which will be a copy of @taglist). The caller's
|
|
reference on @taglist will be removed, and instead the caller will own a
|
|
reference to the returned object.
|
|
|
|
In short, this function unrefs the taglist in the argument and refs the
|
|
taglist that it returns. Don't access the argument after calling this
|
|
function. See also: gst_tag_list_ref().</doc>

with that name is already registered, that one is used.

The old registration may have used a different type however. So don't rely

on your supplied values.
|
|
|
|
Important: if you do not supply a merge function the implication will be
|
|
that there can only be one single value for this tag in a tag list and
|
|
any additional values will silently be discarded when being added (unless
|
|
#GST_TAG_MERGE_REPLACE, #GST_TAG_MERGE_REPLACE_ALL, or
|
|
#GST_TAG_MERGE_PREPEND is used as merge mode, in which case the new
|
|
value will replace the old one in the list).
|
|
|
|
The merge function will be called from gst_tag_list_copy_value() when
|
|
it is required that one or more values for a tag be condensed into
|
|
one single value. This may happen from gst_tag_list_get_string(),
|
|
gst_tag_list_get_int(), gst_tag_list_get_double() etc. What will happen

exactly in that case depends on how the tag was registered and if a

merge function was supplied and if so which one.

upon two arbitrary parameters to remove non-significative terms from
