<!-- 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
|
||||
`AppSinkExt::pull_sample` and `AppSinkExt::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, `AppSinkExt::try_pull_sample` and `AppSinkExt::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 `AppSinkExt::is_eos` method.
|
||||
|
||||
The eos signal can also be used to be informed when the EOS state is reached
|
||||
to avoid polling.

<!-- trait AppSinkExt::fn get_buffer_list_support -->
|
||||
Check if `self` supports buffer lists.
|
||||
|
||||
Feature: `v1_12`
|
||||
|
||||
|
||||
# Returns
|
||||
|
||||
`true` if `self` supports buffer lists.
|
||||
<!-- trait AppSinkExt::fn get_caps -->
|
||||
Get the configured caps on `self`.
|
||||
|
||||
# Returns
|
||||
|
||||
the `gst::Caps` accepted by the sink. `gst_caps_unref` after usage.
|
||||
<!-- trait AppSinkExt::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.
|
||||
<!-- trait AppSinkExt::fn get_emit_signals -->
|
||||
Check if appsink will emit the "new-preroll" and "new-sample" signals.
|
||||
|
||||
# Returns
|
||||
|
||||
`true` if `self` is emiting the "new-preroll" and "new-sample"
|
||||
signals.
|
||||
<!-- trait AppSinkExt::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.
|
||||
<!-- trait AppSinkExt::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.
|
||||
<!-- trait AppSinkExt::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.
|
||||
<!-- trait AppSinkExt::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 sample can be pulled many times
|
||||
and remains available to the application even after EOS.
|
||||
|
||||
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.
|
||||
|
||||
Note that the preroll sample will also be returned as the first sample
|
||||
when calling `AppSinkExt::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.
|
||||
<!-- trait AppSinkExt::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.
|
||||
<!-- trait AppSinkExt::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
|
||||
<!-- trait AppSinkExt::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.
|
||||
## `callbacks`
|
||||
the callbacks
|
||||
## `user_data`
|
||||
a user_data argument for the callbacks
|
||||
## `notify`
|
||||
a destroy notify function
|
||||
<!-- trait AppSinkExt::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
|
||||
<!-- trait AppSinkExt::fn set_drop -->
|
||||
Instruct `self` to drop old buffers when the maximum amount of queued
|
||||
buffers is reached.
|
||||
## `drop`
|
||||
the new state
|
||||
<!-- trait AppSinkExt::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
|
||||
<!-- trait AppSinkExt::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
|
||||
<!-- trait AppSinkExt::fn set_wait_on_eos -->
|
||||
Instruct `self` to wait for all buffers to be consumed when an EOS is received.
|
||||
## `wait`
|
||||
the new state
|
||||
<!-- trait AppSinkExt::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 sample can be pulled many times
|
||||
and remains available to the application even after EOS.
|
||||
|
||||
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.
|
||||
|
||||
Note that the preroll sample will also be returned as the first sample
|
||||
when calling `AppSinkExt::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.
|
||||
<!-- trait AppSinkExt::fn try_pull_sample -->
|
||||
This function blocks until a sample or EOS becomes available or the appsink
|
||||
element is set to the READY/NULL state or the timeout expires.
|
||||
|
||||
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 or the timeout expires,
|
||||
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.
|
||||
<!-- 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
|
||||
`AppSrcExt::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 accessable 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
|
||||
`AppSrcExt::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.

the stream type.
|
||||
<!-- trait AppSrcExt::fn push_buffer -->
|
||||
Adds a buffer to the queue of buffers that the appsrc element will
|
||||
push to its source pad. This function takes ownership of the buffer.
|
||||
|
||||
When the block property is TRUE, this function can block until free
|
||||
space becomes available in the queue.
|
||||
## `buffer`
|
||||
a `gst::Buffer` to push
|
||||
|
||||
# Returns
|
||||
|
||||
`gst::FlowReturn::Ok` when the buffer was successfuly queued.

|
||||
<!-- trait AppSrcExt::fn push_sample -->
|
||||
Extract a buffer from the provided sample and adds it to the queue of
|
||||
buffers that the appsrc element will push to its source pad. Any
|
||||
previous caps that were set on appsrc will be replaced by the caps
|
||||
associated with the sample if not equal.
|
||||
|
||||
When the block property is TRUE, this function can block until free
|
||||
space becomes available in the queue.
|
||||
## `sample`

||||
a `gst::Sample` from which buffer and caps may be
|
||||
extracted

||||
`gst::FlowReturn::Ok` when the buffer was successfuly queued.
|
||||

|
||||
<!-- trait AppSrcExt::fn set_callbacks -->
|
||||
Set callbacks which will be executed when data is needed, enough data has
|
||||
been collected or when a seek should be performed.
|
||||
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.
|
||||

|
||||
<!-- trait AppSrcExt::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.
|
||||
## `caps`
|
||||
caps to set
|
||||
<!-- trait AppSrcExt::fn set_duration -->
|
||||
Set the duration of the stream in nanoseconds. A value of GST_CLOCK_TIME_NONE means that the duration is

||||
Feature: `v1_10`
|
||||
|
||||
## `duration`
|
||||
the duration to set
|
||||
<!-- trait AppSrcExt::fn set_emit_signals -->
|
||||
Make appsrc emit the "new-preroll" and "new-buffer" 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
|
||||
<!-- trait AppSrcExt::fn set_latency -->
|
||||
Configure the `min` and `max` latency in `src`. If `min` is set to -1, the
|
||||
default latency calculations for pseudo-live sources will be used.
|
||||
## `min`
|
||||
the min latency
|
||||
## `max`
|
||||
the min latency
|
||||
<!-- trait AppSrcExt::fn set_max_bytes -->
|
||||
Set the maximum amount of bytes that can be queued in `self`.
|
||||
After the maximum amount of bytes are queued, `self` will emit the
|
||||
"enough-data" signal.
|
||||
## `max`
|
||||
the maximum number of bytes to queue
|
||||
<!-- trait AppSrcExt::fn set_size -->
|
||||
Set the size of the stream in bytes. A value of -1 means that the size is
|
||||
not known.
|
||||
## `size`
|
||||
the size to set
|
||||
<!-- trait AppSrcExt::fn set_stream_type -->
|
||||
Set the stream type on `self`. For seekable streams, the "seek" signal must
|
||||
be connected to.
|
||||
|
||||
A stream_type stream
|
||||
## `type_`
|
||||
the new state
|
||||
<!-- 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.
