      <doc xml:whitespace="preserve">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 buffers from appsink is by using the
gst_app_sink_pull_buffer() and gst_app_sink_pull_preroll() methods.
These methods block until a buffer becomes available in the sink or when the
sink is shut down or reaches EOS.
Appsink will internally use a queue to collect buffers from the streaming
thread. If the application is not pulling buffers 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-buffer" and "new-preroll" signals
when a buffer 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 buffers can be obtained by getting the buffer caps.
If one of the pull-preroll or pull-buffer 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 xml:whitespace="preserve">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 a 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.
The main way of handing data to the appsrc element is by calling the
gst_app_src_push_buffer() method or by emiting 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
emited, 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 model, in which the application repeadedly calls the push-buffer method
with a new buffer. 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 calls. This is a typical mode of operation for the
stream-type "stream" and "seekable". Use this model when implementing various
network protocols or hardware devices.
The pull model where the need-data signal triggers the next push-buffer call.
This mode is typically used in the "random-access" stream-type. Use this
model 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 is 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
happened or the state of the appsrc has gone through READY.
