+      <doc xml:space="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 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">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" 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
+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>
