gst_event_new_sink_message()
gst_event_parse_sink_message()
This event is used for sending a GstMessage downstream and synchronized
with the stream, to be posted by the sink once it reaches the sink.
Fixes bug #602275.
gst_util_greatest_common_divisor()
gst_util_double_to_fraction()
gst_util_fraction_to_double()
Using these instead of going over GValue has much lower overhead.
Also add float<->fraction transform functions for GValue.
This returns the internal feature list cookie, which changes every
time a feature is added or removed. This can be used by elements
to check if they should update their cached feature lists.
This patch adds gst_caps_set_value() and allows gst_caps_set_simple() to
work on non-simple caps. See the API documentation for the functions
about what they do.
The intention of these changes is to ease working with caps in caps
transform functions. An example for this would be ffmpegcolorspace,
where the caps transform function could be changed to look roughly like
this (pseudocode ahead):
result = gst_caps_copy (template_caps);
value = gst_structure_get_value (gst_caps_get_structure (caps, 0),
"widh");
gst_caps_set_value (result, value);
/* same for height, framerate and par */
return caps;
which is much cleaner and easier to understand than the current code.
https://bugzilla.gnome.org/show_bug.cgi?id=597690
In most places in core and baseclasses we just need the caps to do caps-
intersections. In that case ref'ed caps are enough (no need to copy).
This patch also switches the code to use the new functions.
API: gst_pad_get_caps_refed(), gst_pad_peer_get_caps_refed()
Often we don't need the result of the intersection. Add a variant that only
tries to intersect. It can break out earlier and does less GValue copying.
API: gst_caps_can_intersect()
Add a new macro GST_DEBUG_CATEGORY_GET to get a log category by name. This
allows plugins to use e.g. core categories like PERFORMANCE or CLOCK.
API: GST_DEBUG_CATEGORY_GET
Add new method to iterate a bufferlist without having to allocate an iterator.
Add convenience method for getting an item from the list based on the group and
index.
Remove redundant _do_data callback and method.
Update unit-tests and add some more for the new methods.
Add functions to create a new tag list and set tags in one go, which
is nice for use in combination with functions that take ownership of
the taglist, such as gst_event_new_tag() or gst_element_found_tags().
API: add gst_tag_list_new_full()
API: add gst_tag_list_new_full_valist()
Add a bunch of vararg getter convenience functions to complement
the vararg setter functions, and a basic unit test. Fixes#534208.
API: gst_structure_get()
API: gst_structure_id_get()
API: gst_structure_get_valist()
API: gst_structure_id_get_valist()
Add gst_segment_to_position() that converts a running_time to a position in the
segment. A faulty variant of this function is currently used in inputselector
but we'll need it for frame stepping too.
API: GstSegment::gst_segment_to_position()
Add new STEP event and methods for creating/parsing the event
Update design docs.
Add new STEP_DONE message and method to create/parse.
API: GstEvent::gst_event_new_step()
API: GstEvent::gst_event_parse_step()
API: GstMessage::gst_message_new_step_done()
API: GstMessage::gst_message_parse_step_done()
Add a start_time field and some methods. The start_time will contain the
running_time of when the element last went to paused. This time can be user to
report the position in PAUSED but also to do more correct clipping and
stepping later.
Add a gst_element_lost_state_full() with an extra argument to control
distribution of a new base_time. We will need this for flushing step
operations.
API: GstElement::gst_element_lost_state_full()
Reuse buffer code for bufferlists. Not sure if this measurably impacts performance
for the simple buffer case, if it does after doing some benchmarks, we can
decouple it later.
Fixes#572285
Remove the static function set on the TaskPool before _prepare() is called and
allow for assigning a function to a Task when we _push().
Update the examples

in form of a hex dump (#578114).

Yes, 'codec' isn't exactly the best word, but let's be consistent with AUDIO_CODEC
and VIDEO_CODEC (which may be 'raw' formats as well after all). Prerequisite for
bug #576552.
This will be mostly useful in all elements that have some kind of internal
seek/index table. Currently almost all of them (or even all of them)
are using a linear search although the used array is already sorted,
wasting some CPU time without good reason.
Fixes bug #573623.
Add a GST_MESSAGE_REQUEST_STATE that can be posted by element when they would
like to have the application change the state of the pipeline. the primary use
case is to pause the pipeline when an audio mixer is mixing a higher priority
stream but it can also be used for other purposes.
Add some docs and a unit test.
Implement the REQUEST_STATE message in gst-launch.
API: gst_message_new_request_state()
API: gst_message_parse_request_state()
API: GST_MESSAGE_REQUEST_STATE
This tag will list a homepage for the media,
i.e. the artist's or movie's homepage.
This is different to GST_TAG_LOCATION as the latter
lists the original location of the media.
Fixes bug #571227.
Add a property to select the clock type, currently REALTIME and MONOTONIC when
posix timers are available.
Implement the systemclock with GstPoll instead of GCond. This allows us to
schedule timeouts with nanosecond precission on newer kernels and with ppoll
support. It's also resilient to changes to the systemclock because of NTP or
similar.
Add a special timer mode in GstPoll that makes it only use the control socket
with a timeout to schedule timeouts. Also add a pair of methods to wakeup the
timeout thread.
API: GstPoll::gst_poll_new_timer()
API: GstPoll::gst_poll_write_control()
API: GstPoll::gst_poll_read_control()

Remove GST_DISABLE_(ENUMTYPES|INDEX|URI) everywhere.
Disabling the indexers and URI handler code will only reduce the
required amount of memory by a very small amount but on the other hand
requires much more maintaince work. Apart from that many places of
code are broken when disabling them.
Disabling the enum types doesn't reduce the required amount of memory
by more than a few bytes and makes it hard to fix bugs like #539772,
i.e. use the enums as GObject properties.
