/**
* SECTION:gstappsrc
* @short_description: Easy way for applications to inject buffers into a
* pipeline
* @see_also: #GstBaseSrc, appsink
*
* 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 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 model, in which the application repeatedly 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.
*
2011-05-23 12:02:27 +00:00
* 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.
