# How to update the bindings
|
||||
|
||||
* Take the updated .gir files (e.g. from your gst-build checkout) and put
|
||||
them in the gir-files directory
|
||||
* In the gir-files directory, run ./fix.sh
|
||||
* Make sure gstreamer-rs-sys is up to date
|
||||
* Take the updated .gir files from gstreamer-rs-sys and copy them over
|
||||
* If there is a new GStreamer version: Manually update `gst*/Cargo.toml`
|
||||
* Run generator.py
|
||||
* Investigate the diff, fix any mess-ups, look at commented functions and

provided by the GStreamer project.
|

|

We recommend using the official GStreamer binaries over Homebrew, especially
|
||||
as GStreamer in Homebrew is [currently broken](https://github.com/orgs/Homebrew/discussions/3740#discussioncomment-3804964).
|
||||
#### Homebrew
|
||||
|
||||
```
|
||||
$ brew install gstreamer gst-plugins-base gst-plugins-good \

|
||||
sufficient.
|
||||
|
||||
#### GStreamer Binaries
|
||||
|
||||
You need to download the *two* `.pkg` files from the GStreamer website and
|
||||
install them, e.g. `gstreamer-1.0-1.20.4-universal.pkg` and
|
||||
`gstreamer-1.0-devel-1.20.4-universal.pkg`.
|
||||
install them, e.g. `gstreamer-1.0-1.12.3-x86_64.pkg` and
|
||||
`gstreamer-1.0-devel-1.12.3-x86_64.pkg`.
|
||||
|
||||
After installation, you also need to set the `PATH` environment variable as
|
||||
follows
|
||||
After installation, you also need to install `pkg-config` (e.g. via Homebrew)
|
||||
and set the `PKG_CONFIG_PATH` environment variable
|
||||
|
||||
```console
|
||||
$ export PATH="/Library/Frameworks/GStreamer.framework/Versions/1.0/bin${PATH:+:$PATH}"
|
||||
```
|
||||
|
||||
Also note that the `pkg-config` from GStreamer should be the first one in
|
||||
the `PATH` as other versions have all kinds of quirks that will cause
|
||||
problems.
|
||||
|
||||
#### Homebrew
|
||||
|
||||
Homebrew only installs various plugins if explicitly enabled, so some extra
|
||||
`--with-*` flags may be required.

||||

We recommend using the official GStreamer binaries over MSYS2.

|
||||
You need to download the *two* `.msi` files for your platform from the
|

GStreamer website and install them, e.g. `gstreamer-1.0-x86_64-1.20.4.msi` and
|

matches your Rust toolchain, i.e. MinGW or MSVC.

After installation set the ``PATH` environment variable as follows:

Make sure to update the path to where you have actually installed GStreamer
|
||||
and for the corresponding toolchain.

Also note that the `pkg-config.exe` from GStreamer should be the first one in
|

the `PATH` as other versions have all kinds of quirks that will cause

<!-- file * -->

<!-- struct AppSink -->
|
||||
Appsink is a sink plugin that supports many different methods for making
|
||||
the application get a handle on the GStreamer data in a pipeline. Unlike
|
||||
most GStreamer elements, Appsink provides external API functions.
|
||||
|
||||
appsink can be used by linking to the gstappsink.h header file to access the
|
||||
methods or by using the appsink action signals and properties.
|
||||
|
||||
The normal way of retrieving samples from appsink is by using the
|
||||
`AppSink::pull_sample` and `AppSink::pull_preroll` methods.
|
||||
These methods block until a sample becomes available in the sink or when the
|
||||
sink is shut down or reaches EOS. There are also timed variants of these
|
||||
methods, `AppSink::try_pull_sample` and `AppSink::try_pull_preroll`,
|
||||
which accept a timeout parameter to limit the amount of time to wait.
|
||||
|
||||
Appsink will internally use a queue to collect buffers from the streaming
|
||||
thread. If the application is not pulling samples fast enough, this queue
|
||||
will consume a lot of memory over time. The "max-buffers" property can be
|
||||
used to limit the queue size. The "drop" property controls whether the
|
||||
streaming thread blocks or if older buffers are dropped when the maximum
|
||||
queue size is reached. Note that blocking the streaming thread can negatively
|
||||
affect real-time performance and should be avoided.
|
||||
|
||||
If a blocking behaviour is not desirable, setting the "emit-signals" property
|
||||
to `true` will make appsink emit the "new-sample" and "new-preroll" signals
|
||||
when a sample can be pulled without blocking.
|
||||
|
||||
The "caps" property on appsink can be used to control the formats that
|
||||
appsink can receive. This property can contain non-fixed caps, the format of
|
||||
the pulled samples can be obtained by getting the sample caps.
|
||||
|
||||
If one of the pull-preroll or pull-sample methods return `None`, the appsink
|
||||
is stopped or in the EOS state. You can check for the EOS state with the
|
||||
"eos" property or with the `AppSink::is_eos` method.
|
||||
|
||||
The eos signal can also be used to be informed when the EOS state is reached
|
||||
to avoid polling.

[`gst_base::BaseSinkExt`](../gst_base/trait.BaseSinkExt.html), [`gst::ElementExt`](../gst/trait.ElementExt.html), [`gst::ObjectExt`](../gst/trait.ObjectExt.html), [`glib::object::ObjectExt`](../glib/object/trait.ObjectExt.html), [`gst::URIHandlerExt`](../gst/trait.URIHandlerExt.html)
|
||||
<!-- impl AppSink::fn get_buffer_list_support -->
|
||||
Check if `self` supports buffer lists.
|
||||
|
||||
Feature: `v1_12`
|
||||
|
||||
|
||||
# Returns
|
||||
|
||||
`true` if `self` supports buffer lists.
|
||||
<!-- impl AppSink::fn get_caps -->
|
||||
Get the configured caps on `self`.
|
||||
|
||||
# Returns
|
||||
|
||||
the `gst::Caps` accepted by the sink. `gst::Caps::unref` after usage.
|
||||
<!-- impl AppSink::fn get_drop -->
|
||||
Check if `self` will drop old buffers when the maximum amount of queued
|
||||
buffers is reached.
|
||||
|
||||
# Returns
|
||||
|
||||
`true` if `self` is dropping old buffers when the queue is
|
||||
filled.
|
||||
<!-- impl AppSink::fn get_emit_signals -->
|
||||
Check if appsink will emit the "new-preroll" and "new-sample" signals.
|
||||
|
||||
# Returns
|
||||
|
||||
`true` if `self` is emitting the "new-preroll" and "new-sample"
|
||||
signals.
|
||||
<!-- impl AppSink::fn get_max_buffers -->
|
||||
Get the maximum amount of buffers that can be queued in `self`.
|
||||
|
||||
# Returns
|
||||
|
||||
The maximum amount of buffers that can be queued.
|
||||
<!-- impl AppSink::fn get_wait_on_eos -->
|
||||
Check if `self` will wait for all buffers to be consumed when an EOS is
|
||||
received.
|
||||
|
||||
# Returns
|
||||
|
||||
`true` if `self` will wait for all buffers to be consumed when an
|
||||
EOS is received.
|
||||
<!-- impl AppSink::fn is_eos -->
|
||||
Check if `self` is EOS, which is when no more samples can be pulled because
|
||||
an EOS event was received.
|
||||
|
||||
This function also returns `true` when the appsink is not in the PAUSED or
|
||||
PLAYING state.
|
||||
|
||||
# Returns
|
||||
|
||||
`true` if no more samples can be pulled and the appsink is EOS.
|
||||
<!-- impl AppSink::fn pull_preroll -->
|
||||
Get the last preroll sample in `self`. This was the sample that caused the
|
||||
appsink to preroll in the PAUSED state.
|
||||
|
||||
This function is typically used when dealing with a pipeline in the PAUSED
|
||||
state. Calling this function after doing a seek will give the sample right
|
||||
after the seek position.
|
||||
|
||||
Calling this function will clear the internal reference to the preroll
|
||||
buffer.
|
||||
|
||||
Note that the preroll sample will also be returned as the first sample
|
||||
when calling `AppSink::pull_sample`.
|
||||
|
||||
If an EOS event was received before any buffers, this function returns
|
||||
`None`. Use gst_app_sink_is_eos () to check for the EOS condition.
|
||||
|
||||
This function blocks until a preroll sample or EOS is received or the appsink
|
||||
element is set to the READY/NULL state.
|
||||
|
||||
# Returns
|
||||
|
||||
a `gst::Sample` or NULL when the appsink is stopped or EOS.
|
||||
Call `gst::Sample::unref` after usage.
|
||||
<!-- impl AppSink::fn pull_sample -->
|
||||
This function blocks until a sample or EOS becomes available or the appsink
|
||||
element is set to the READY/NULL state.
|
||||
|
||||
This function will only return samples when the appsink is in the PLAYING
|
||||
state. All rendered buffers will be put in a queue so that the application
|
||||
can pull samples at its own rate. Note that when the application does not
|
||||
pull samples fast enough, the queued buffers could consume a lot of memory,
|
||||
especially when dealing with raw video frames.
|
||||
|
||||
If an EOS event was received before any buffers, this function returns
|
||||
`None`. Use gst_app_sink_is_eos () to check for the EOS condition.
|
||||
|
||||
# Returns
|
||||
|
||||
a `gst::Sample` or NULL when the appsink is stopped or EOS.
|
||||
Call `gst::Sample::unref` after usage.
|
||||
<!-- impl AppSink::fn set_buffer_list_support -->
|
||||
Instruct `self` to enable or disable buffer list support.
|
||||
|
||||
For backwards-compatibility reasons applications need to opt in
|
||||
to indicate that they will be able to handle buffer lists.
|
||||
|
||||
Feature: `v1_12`
|
||||
|
||||
## `enable_lists`
|
||||
enable or disable buffer list support
|
||||
<!-- impl AppSink::fn set_callbacks -->
|
||||
Set callbacks which will be executed for each new preroll, new sample and eos.
|
||||
This is an alternative to using the signals, it has lower overhead and is thus
|
||||
less expensive, but also less flexible.
|
||||
|
||||
If callbacks are installed, no signals will be emitted for performance
|
||||
reasons.
|
||||
|
||||
Before 1.16.3 it was not possible to change the callbacks in a thread-safe
|
||||
way.
|
||||
## `callbacks`
|
||||
the callbacks
|
||||
## `user_data`
|
||||
a user_data argument for the callbacks
|
||||
## `notify`
|
||||
a destroy notify function
|
||||
<!-- impl AppSink::fn set_caps -->
|
||||
Set the capabilities on the appsink element. This function takes
|
||||
a copy of the caps structure. After calling this method, the sink will only
|
||||
accept caps that match `caps`. If `caps` is non-fixed, or incomplete,
|
||||
you must check the caps on the samples to get the actual used caps.
|
||||
## `caps`
|
||||
caps to set
|
||||
<!-- impl AppSink::fn set_drop -->
|
||||
Instruct `self` to drop old buffers when the maximum amount of queued
|
||||
buffers is reached.
|
||||
## `drop`
|
||||
the new state
|
||||
<!-- impl AppSink::fn set_emit_signals -->
|
||||
Make appsink emit the "new-preroll" and "new-sample" signals. This option is
|
||||
by default disabled because signal emission is expensive and unneeded when
|
||||
the application prefers to operate in pull mode.
|
||||
## `emit`
|
||||
the new state
|
||||
<!-- impl AppSink::fn set_max_buffers -->
|
||||
Set the maximum amount of buffers that can be queued in `self`. After this
|
||||
amount of buffers are queued in appsink, any more buffers will block upstream
|
||||
elements until a sample is pulled from `self`.
|
||||
## `max`
|
||||
the maximum number of buffers to queue
|
||||
<!-- impl AppSink::fn set_wait_on_eos -->
|
||||
Instruct `self` to wait for all buffers to be consumed when an EOS is received.
|
||||
## `wait`
|
||||
the new state
|
||||
<!-- impl AppSink::fn try_pull_preroll -->
|
||||
Get the last preroll sample in `self`. This was the sample that caused the
|
||||
appsink to preroll in the PAUSED state.
|
||||
|
||||
This function is typically used when dealing with a pipeline in the PAUSED
|
||||
state. Calling this function after doing a seek will give the sample right
|
||||
after the seek position.
|
||||
|
||||
Calling this function will clear the internal reference to the preroll
|
||||
buffer.
|
||||
|
||||
Note that the preroll sample will also be returned as the first sample
|
||||
when calling `AppSink::pull_sample`.
|
||||
|
||||
If an EOS event was received before any buffers or the timeout expires,
|
||||
this function returns `None`. Use gst_app_sink_is_eos () to check for the EOS
|
||||
condition.
|
||||
|
||||
This function blocks until a preroll sample or EOS is received, the appsink
|
||||
element is set to the READY/NULL state, or the timeout expires.
|
||||
|
||||
Feature: `v1_10`
|
||||
|
||||
## `timeout`
|
||||
the maximum amount of time to wait for the preroll sample
|
||||
|
||||
# Returns
|
||||
|
||||
a `gst::Sample` or NULL when the appsink is stopped or EOS or the timeout expires.
|
||||
Call `gst::Sample::unref` after usage.
|
||||
<!-- impl AppSink::fn try_pull_sample -->
|
||||
This function blocks until a sample or EOS becomes available or the appsink
|

this function returns `None`. Use gst_app_sink_is_eos () to check for the EOS
|
||||
condition.
|
||||
|
||||
Feature: `v1_10`
|
||||
|
||||
## `timeout`
|
||||
the maximum amount of time to wait for a sample
|
||||
|
||||
# Returns
|
||||
|
||||
a `gst::Sample` or NULL when the appsink is stopped or EOS or the timeout expires.
|
||||
Call `gst::Sample::unref` after usage.
|
||||
<!-- impl AppSink::fn connect_eos -->
|
||||
Signal that the end-of-stream has been reached. This signal is emitted from
|
||||
the streaming thread.
|
||||
<!-- impl AppSink::fn connect_new_preroll -->
|
||||
Signal that a new preroll sample is available.
|
||||
|
||||
This signal is emitted from the streaming thread and only when the
|
||||
"emit-signals" property is `true`.
|
||||
|
||||
The new preroll sample can be retrieved with the "pull-preroll" action
|
||||
signal or `AppSink::pull_preroll` either from this signal callback
|
||||
or from any other thread.
|
||||
|
||||
Note that this signal is only emitted when the "emit-signals" property is
|
||||
set to `true`, which it is not by default for performance reasons.
|
||||
<!-- impl AppSink::fn connect_new_sample -->
|
||||
Signal that a new sample is available.
|
||||
|
||||
This signal is emitted from the streaming thread and only when the
|
||||
"emit-signals" property is `true`.
|
||||
|
||||
The new sample can be retrieved with the "pull-sample" action
|
||||
signal or `AppSink::pull_sample` either from this signal callback
|
||||
or from any other thread.
|

||||
<!-- struct AppSrc -->
|
||||
The appsrc element can be used by applications to insert data into a
|
||||
GStreamer pipeline. Unlike most GStreamer elements, appsrc provides
|
||||
external API functions.
|
||||
|
||||
appsrc can be used by linking with the libgstapp library to access the
|
||||
methods directly or by using the appsrc action signals.
|
||||
|
||||
Before operating appsrc, the caps property must be set to fixed caps
|
||||
describing the format of the data that will be pushed with appsrc. An
|
||||
exception to this is when pushing buffers with unknown caps, in which case no
|
||||
caps should be set. This is typically true of file-like sources that push raw
|
||||
byte buffers. If you don't want to explicitly set the caps, you can use
|
||||
gst_app_src_push_sample. This method gets the caps associated with the
|
||||
sample and sets them on the appsrc replacing any previously set caps (if
|
||||
different from sample's caps).
|
||||
|
||||
The main way of handing data to the appsrc element is by calling the
|
||||
`AppSrc::push_buffer` method or by emitting the push-buffer action signal.
|
||||
This will put the buffer onto a queue from which appsrc will read from in its
|
||||
streaming thread. It is important to note that data transport will not happen
|
||||
from the thread that performed the push-buffer call.
|
||||
|
||||
The "max-bytes" property controls how much data can be queued in appsrc
|
||||
before appsrc considers the queue full. A filled internal queue will always
|
||||
signal the "enough-data" signal, which signals the application that it should
|
||||
stop pushing data into appsrc. The "block" property will cause appsrc to
|
||||
block the push-buffer method until free data becomes available again.
|
||||
|
||||
When the internal queue is running out of data, the "need-data" signal is
|
||||
emitted, which signals the application that it should start pushing more data
|
||||
into appsrc.
|
||||
|
||||
In addition to the "need-data" and "enough-data" signals, appsrc can emit the
|
||||
"seek-data" signal when the "stream-mode" property is set to "seekable" or
|
||||
"random-access". The signal argument will contain the new desired position in
|
||||
the stream expressed in the unit set with the "format" property. After
|
||||
receiving the seek-data signal, the application should push-buffers from the
|
||||
new position.
|
||||
|
||||
These signals allow the application to operate the appsrc in two different
|
||||
ways:
|
||||
|
||||
The push mode, in which the application repeatedly calls the push-buffer/push-sample
|
||||
method with a new buffer/sample. Optionally, the queue size in the appsrc
|
||||
can be controlled with the enough-data and need-data signals by respectively
|
||||
stopping/starting the push-buffer/push-sample calls. This is a typical
|
||||
mode of operation for the stream-type "stream" and "seekable". Use this
|
||||
mode when implementing various network protocols or hardware devices.
|
||||
|
||||
The pull mode, in which the need-data signal triggers the next push-buffer call.
|
||||
This mode is typically used in the "random-access" stream-type. Use this
|
||||
mode for file access or other randomly accessible sources. In this mode, a
|
||||
buffer of exactly the amount of bytes given by the need-data signal should be
|
||||
pushed into appsrc.
|
||||
|
||||
In all modes, the size property on appsrc should contain the total stream
|
||||
size in bytes. Setting this property is mandatory in the random-access mode.
|
||||
For the stream and seekable modes, setting this property is optional but
|
||||
recommended.
|
||||
|
||||
When the application has finished pushing data into appsrc, it should call
|
||||
`AppSrc::end_of_stream` or emit the end-of-stream action signal. After
|
||||
this call, no more buffers can be pushed into appsrc until a flushing seek
|
||||
occurs or the state of the appsrc has gone through READY.

If callbacks are installed, no signals will be emitted for performance
|

<!-- impl AppSrc::fn set_caps -->
|
||||
Set the capabilities on the appsrc element. This function takes
|
||||
a copy of the caps structure. After calling this method, the source will
|
||||
only produce caps that match `caps`. `caps` must be fixed and the caps on the
|
||||
buffers must match the caps or left NULL.

||||
## `emit`
|
||||
the new state
|
||||
<!-- impl AppSrc::fn set_latency -->
|
||||
Configure the `min` and `max` latency in `src`. If `min` is set to -1, the

<!-- impl AppSrc::fn set_stream_type -->
|
||||
Set the stream type on `self`. For seekable streams, the "seek" signal must
|
||||
be connected to.

the new state
|

<!-- impl AppSrc::fn connect_end_of_stream -->
|
||||
Notify `appsrc` that no more buffer are available.
|
||||
<!-- impl AppSrc::fn connect_enough_data -->
|
||||
Signal that the source has enough data. It is recommended that the
|
||||
application stops calling push-buffer until the need-data signal is
|
||||
emitted again to avoid excessive buffer queueing.
|
||||
<!-- impl AppSrc::fn connect_need_data -->
|
||||
Signal that the source needs more data. In the callback or from another
|
||||
thread you should call push-buffer or end-of-stream.
|
||||
|
||||
`length` is just a hint and when it is set to -1, any number of bytes can be
|

You can call push-buffer multiple times until the enough-data signal is
|

<!-- impl AppSrc::fn connect_push_buffer -->
|
||||
Adds a buffer to the queue of buffers that the appsrc element will
|

push to its source pad. This function does not take ownership of the
|
||||
buffer so the buffer needs to be unreffed after calling this function.
|
||||
|

When the block property is TRUE, this function can block until free space
|
||||
becomes available in the queue.
|
||||
## `buffer`
|

<!-- impl AppSrc::fn connect_push_buffer_list -->
|
||||
Adds a buffer list to the queue of buffers and buffer lists that the

appsrc element will push to its source pad. This function does not take
|
||||
ownership of the buffer list so the buffer list needs to be unreffed
|

When the block property is TRUE, this function can block until free space
|
||||
becomes available in the queue.

## `buffer_list`
|
||||
a buffer list to push

<!-- impl AppSrc::fn connect_push_sample -->
|
||||
Extract a buffer from the provided sample and adds the extracted buffer
|
||||
to the queue of buffers that the appsrc element will
|
||||
push to its source pad. This function set the appsrc caps based on the caps
|
||||
in the sample and reset the caps if they change.
|
||||
Only the caps and the buffer of the provided sample are used and not
|
||||
for example the segment in the sample.
|
||||
This function does not take ownership of the
|
||||
sample so the sample needs to be unreffed after calling this function.
|
||||
|
||||
When the block property is TRUE, this function can block until free space
|

becomes available in the queue.
|
||||
## `sample`
|

a sample from which extract buffer to push
|
||||
<!-- impl AppSrc::fn connect_seek_data -->
|
||||
Seek to the given offset. The next push-buffer should produce buffers from
|

the new `offset`.
|
||||
This callback is only called for seekable stream types.
|
||||
## `offset`
|
||||
the offset to seek to

# Returns
|
||||
|
||||
`true` if the seek succeeded.
|
||||
<!-- enum AppStreamType -->
|
||||
The stream type.
|
||||
<!-- enum AppStreamType::variant Stream -->
|
||||
No seeking is supported in the stream, such as a
|
||||
live stream.
|
||||
<!-- enum AppStreamType::variant Seekable -->
|
||||
The stream is seekable but seeking might not
|
||||
be very fast, such as data from a webserver.
|
||||
<!-- enum AppStreamType::variant RandomAccess -->
|
||||
The stream is seekable and seeking is fast,
|
||||
such as in a local file.

<!-- struct TestClock -->
|
||||
GstTestClock is an implementation of `gst::Clock` which has different
|
||||
behaviour compared to `gst::SystemClock`. Time for `gst::SystemClock` advances
|
||||
according to the system time, while time for `TestClock` changes only
|
||||
when `TestClock::set_time` or `TestClock::advance_time` are
|
||||
called. `TestClock` provides unit tests with the possibility to
|
||||
precisely advance the time in a deterministic manner, independent of the
|
||||
system time or any other external factors.
|
||||
|
||||
## Advancing the time of a `TestClock`
|
||||
|
||||
|
||||
```C
|
||||
#include <gst/gst.h>
|
||||
#include <gst/check/gsttestclock.h>
|
||||
|
||||
GstClock *clock;
|
||||
GstTestClock *test_clock;
|
||||
|
||||
clock = gst_test_clock_new ();
|
||||
test_clock = GST_TEST_CLOCK (clock);
|
||||
GST_INFO ("Time: %" GST_TIME_FORMAT, GST_TIME_ARGS (gst_clock_get_time (clock)));
|
||||
gst_test_clock_advance_time ( test_clock, 1 * GST_SECOND);
|
||||
GST_INFO ("Time: %" GST_TIME_FORMAT, GST_TIME_ARGS (gst_clock_get_time (clock)));
|
||||
g_usleep (10 * G_USEC_PER_SEC);
|
||||
GST_INFO ("Time: %" GST_TIME_FORMAT, GST_TIME_ARGS (gst_clock_get_time (clock)));
|
||||
gst_test_clock_set_time (test_clock, 42 * GST_SECOND);
|
||||
GST_INFO ("Time: %" GST_TIME_FORMAT, GST_TIME_ARGS (gst_clock_get_time (clock)));
|
||||
...
|
||||
```
|
||||
|
||||
`gst::Clock` allows for setting up single shot or periodic clock notifications
|
||||
as well as waiting for these notifications synchronously (using
|
||||
`gst::Clock::id_wait`) or asynchronously (using `gst::Clock::id_wait_async` or
|
||||
`gst::Clock::id_wait_async`). This is used by many GStreamer elements,
|
||||
among them `GstBaseSrc` and `GstBaseSink`.
|
||||
|
||||
`TestClock` keeps track of these clock notifications. By calling
|
||||
`TestClock::wait_for_next_pending_id` or
|
||||
`TestClock::wait_for_multiple_pending_ids` a unit tests may wait for the
|
||||
next one or several clock notifications to be requested. Additionally unit
|
||||
tests may release blocked waits in a controlled fashion by calling
|
||||
`TestClock::process_next_clock_id`. This way a unit test can control the
|
||||
inaccuracy (jitter) of clock notifications, since the test can decide to
|
||||
release blocked waits when the clock time has advanced exactly to, or past,
|
||||
the requested clock notification time.
|
||||
|
||||
There are also interfaces for determining if a notification belongs to a
|
||||
`TestClock` or not, as well as getting the number of requested clock
|
||||
notifications so far.
|
||||
|
||||
N.B.: When a unit test waits for a certain amount of clock notifications to
|
||||
be requested in `TestClock::wait_for_next_pending_id` or
|
||||
`TestClock::wait_for_multiple_pending_ids` then these functions may block
|
||||
for a long time. If they block forever then the expected clock notifications
|
||||
were never requested from `TestClock`, and so the assumptions in the code
|
||||
of the unit test are wrong. The unit test case runner in gstcheck is
|
||||
expected to catch these cases either by the default test case timeout or the
|
||||
one set for the unit test by calling tcase_set_timeout\(\).
|
||||
|
||||
The sample code below assumes that the element under test will delay a
|
||||
buffer pushed on the source pad by some latency until it arrives on the sink
|
||||
pad. Moreover it is assumed that the element will at some point call
|
||||
`gst::Clock::id_wait` to synchronously wait for a specific time. The first
|
||||
buffer sent will arrive exactly on time only delayed by the latency. The
|
||||
second buffer will arrive a little late (7ms) due to simulated jitter in the
|
||||
clock notification.
|
||||

||||

<!-- struct NetClientClock -->
|
||||
`NetClientClock` implements a custom `gst::Clock` that synchronizes its time
|
||||
to a remote time provider such as `NetTimeProvider`. `NtpClock`
|
||||
implements a `gst::Clock` that synchronizes its time to a remote NTPv4 server.
|
||||
|
||||
A new clock is created with `NetClientClock::new` or
|
||||
`NtpClock::new`, which takes the address and port of the remote time
|
||||
provider along with a name and an initial time.
|
||||
|
||||
This clock will poll the time provider and will update its calibration
|
||||
parameters based on the local and remote observations.
|
||||
|
||||
The "round-trip" property limits the maximum round trip packets can take.
|
||||
|
||||
Various parameters of the clock can be configured with the parent `gst::Clock`
|
||||
"timeout", "window-size" and "window-threshold" object properties.
|
||||
|
||||
A `NetClientClock` and `NtpClock` is typically set on a `gst::Pipeline` with
|
||||
`gst::Pipeline::use_clock`.
|
||||
|
||||
If you set a `gst::Bus` on the clock via the "bus" object property, it will
|
||||
send `gst::MessageType::Element` messages with an attached `gst::Structure` containing
|
||||
statistics about clock accuracy and network traffic.
|
||||
|
||||
# Implements

|
||||
<!-- impl NetClientClock::fn new -->
|
||||

|
||||
provided by the `NetTimeProvider` on `remote_address` and
|
||||
`remote_port`.
|
||||
## `name`

## `remote_address`
|

## `remote_port`
|
||||
the port of the remote clock provider
|
||||
## `base_time`
|
||||
initial time of the clock
|
||||
|
||||
# Returns
|
||||
|
||||
a new `gst::Clock` that receives a time from the remote
|
||||
clock.
|
||||
<!-- struct NetTimeProvider -->
|
||||
This object exposes the time of a `gst::Clock` on the network.
|
||||
|
||||
A `NetTimeProvider` is created with `NetTimeProvider::new` which
|
||||
takes a `gst::Clock`, an address and a port number as arguments.
|
||||
|
||||
After creating the object, a client clock such as `NetClientClock` can
|
||||
query the exposed clock over the network for its values.
|
||||
|
||||
The `NetTimeProvider` typically wraps the clock used by a `gst::Pipeline`.

||||

|
||||
Allows network clients to get the current time of `clock`.
|

## `clock`
|

a `gst::Clock` to export over the network
|

<!-- struct PtpClock -->
|
||||
GstPtpClock implements a PTP (IEEE1588:2008) ordinary clock in slave-only
|
||||
mode, that allows a GStreamer pipeline to synchronize to a PTP network
|
||||
clock in some specific domain.
|
||||
|
||||
The PTP subsystem can be initialized with `gst_ptp_init`, which then starts
|
||||
a helper process to do the actual communication via the PTP ports. This is
|
||||
required as PTP listens on ports < 1024 and thus requires special
|
||||
privileges. Once this helper process is started, the main process will
|
||||
synchronize to all PTP domains that are detected on the selected
|
||||
interfaces.
|
||||
|
||||
`PtpClock::new` then allows to create a GstClock that provides the PTP
|
||||
time from a master clock inside a specific PTP domain. This clock will only
|
||||
return valid timestamps once the timestamps in the PTP domain are known. To
|
||||
check this, you can use `gst::ClockExt::wait_for_sync`, the GstClock::synced
|
||||
signal and `gst::ClockExt::is_synced`.
|
||||
|
||||
To gather statistics about the PTP clock synchronization,
|
||||
`gst_ptp_statistics_callback_add` can be used. This gives the application
|
||||
the possibility to collect all kinds of statistics from the clock
|
||||
synchronization.
|
||||
|
||||
# Implements
|
||||
|
||||
[`gst::ClockExt`](../gst/trait.ClockExt.html), [`gst::ObjectExt`](../gst/trait.ObjectExt.html), [`glib::object::ObjectExt`](../glib/object/trait.ObjectExt.html)
|
||||
<!-- impl PtpClock::fn new -->
|
||||
Creates a new PTP clock instance that exports the PTP time of the master
|
||||
clock in `domain`. This clock can be slaved to other clocks as needed.
|
||||
|
||||
If `gst_ptp_init` was not called before, this will call `gst_ptp_init` with
|
||||
default parameters.
|
||||
|
||||
This clock only returns valid timestamps after it received the first
|
||||
times from the PTP master clock on the network. Once this happens the
|
||||
GstPtpClock::internal-clock property will become non-NULL. You can
|
||||
check this with `gst::ClockExt::wait_for_sync`, the GstClock::synced signal and
|
||||
`gst::ClockExt::is_synced`.

<!-- struct Discoverer -->
|
||||
The `Discoverer` is a utility object which allows to get as much
|
||||
information as possible from one or many URIs.
|
||||
|
||||
It provides two APIs, allowing usage in blocking or non-blocking mode.
|
||||
|
||||
The blocking mode just requires calling `Discoverer::discover_uri`
|
||||
with the URI one wishes to discover.
|
||||
|
||||
The non-blocking mode requires a running `glib::MainLoop` iterating a
|
||||
`glib::MainContext`, where one connects to the various signals, appends the
|
||||
URIs to be processed (through `Discoverer::discover_uri_async`) and then
|
||||
asks for the discovery to begin (through `Discoverer::start`).
|
||||
By default this will use the GLib default main context unless you have
|
||||
set a custom context using `glib::MainContext::push_thread_default`.
|
||||
|
||||
All the information is returned in a `DiscovererInfo` structure.
|
||||
|
||||
# Implements
|
||||
|
||||
[`glib::object::ObjectExt`](../glib/object/trait.ObjectExt.html)
|

<!-- impl Discoverer::fn new -->
|

Creates a new `Discoverer` with the provided timeout.
|

## `timeout`
|
||||
timeout per file, in nanoseconds. Allowed are values between
|
||||
one second (`GST_SECOND`) and one hour (3600 * `GST_SECOND`)
|
||||
|
||||
# Returns
|
||||
|
||||
The new `Discoverer`.
|
||||
If an error occurred when creating the discoverer, `err` will be set
|
||||
accordingly and `None` will be returned. If `err` is set, the caller must
|
||||
free it when no longer needed using `glib::Error::free`.
|
||||
<!-- impl Discoverer::fn discover_uri -->
|
||||
Synchronously discovers the given `uri`.
|

A copy of `uri` will be made internally, so the caller can safely `g_free`
|
||||
afterwards.
|
||||
## `uri`
|
||||
The URI to run on.
|
||||
|

# Returns
|

|
||||
the result of the scanning. Can be `None` if an
|
||||
error occurred.
|

<!-- impl Discoverer::fn discover_uri_async -->
|

discovery of the `uri` will only take place if `Discoverer::start` has
|
||||
been called.
|
||||
|

uris, else `false`
|
||||
<!-- impl Discoverer::fn start -->
|
||||
Allow asynchronous discovering of URIs to take place.
|
||||
A `glib::MainLoop` must be available for `Discoverer` to properly work in
|
||||
asynchronous mode.
|
||||
<!-- impl Discoverer::fn stop -->
|
||||
Stop the discovery of any pending URIs and clears the list of
|
||||
pending URIS (if any).
|
||||
<!-- impl Discoverer::fn connect_discovered -->
|
||||
Will be emitted in async mode when all information on a URI could be
|
||||
discovered, or an error occurred.
|
||||
|
||||
When an error occurs, `info` might still contain some partial information,
|
||||
depending on the circumstances of the error.
|
||||
## `info`
|
||||
the results `DiscovererInfo`
|
||||
## `error`
|
||||
`glib::Error`, which will be non-NULL
|

<!-- impl RTSPUrl::fn decode_path_components -->
|
||||
Splits the path of `self` on '/' boundaries, decoding the resulting components,
|
||||
|
||||
The decoding performed by this routine is "URI decoding", as defined in RFC
|
||||
3986, commonly known as percent-decoding. For example, a string "foo\%2fbar"
|
||||
will decode to "foo/bar" -- the \%2f being replaced by the corresponding byte
|
||||
with hex value 0x2f. Note that there is no guarantee that the resulting byte
|
||||
sequence is valid in any given encoding. As a special case, \%00 is not
|
||||
unescaped to NUL, as that would prematurely terminate the string.
|
||||
|
||||
Also note that since paths usually start with a slash, the first component
|
||||
will usually be the empty string.
|
||||
|
||||
# Returns
|
||||
|
||||
`None`-terminated array of URL components. Free with

`g_strfreev` when no longer needed.
