<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/app/gstappsink.c">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
|
|
gst_app_sink_pull_sample() and gst_app_sink_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, gst_app_sink_try_pull_sample() and gst_app_sink_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 %NULL, the appsink
|
|
is stopped or in the EOS state. You can check for the EOS state with the
|
|
"eos" property or with the gst_app_sink_is_eos() method.
|
|
|
|
The eos signal can also be used to be informed when the EOS state is reached
|
|
to avoid polling.</doc>

<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/app/gstappsrc.c">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
|
|
gst_app_src_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", "max-buffers" and "max-time" properties control 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
|
|
gst_app_src_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.</doc>
