- * Subclass is responsible for providing pad template caps for
- * source and sink pads. The pads need to be named "sink" and "src". It also
- * needs to set the fixed caps on srcpad, when the format is ensured. This
- * is typically when base class calls subclass' @set_format function, though
- * it might be delayed until calling @gst_base_video_decoder_finish_frame.
- *
- * Subclass is also responsible for providing (presentation) timestamps
- * (likely based on corresponding input ones). If that is not applicable
- * or possible, baseclass provides limited framerate based interpolation.
- *
- * Similarly, the baseclass provides some limited (legacy) seeking support
- * (upon explicit subclass request), as full-fledged support
- * should rather be left to upstream demuxer, parser or alike. This simple
- * approach caters for seeking and duration reporting using estimated input
- * bitrates.
- *
- * Baseclass provides some support for reverse playback, in particular
- * in case incoming data is not packetized or upstream does not provide
- * fragments on keyframe boundaries. However, subclass should then be prepared
- * for the parsing and frame processing stage to occur separately (rather
- * than otherwise the latter immediately following the former),
- * and should ensure the parsing stage properly marks keyframes or rely on
- * upstream to do so properly for incoming data.
- *
- * Things that subclass need to take care of:

- * Set source pad caps when appropriate

- * <listitem><para>
- * Configure some baseclass behaviour parameters.
- * </para></listitem>
- * <listitem><para>
- * Optionally parse input data, if it is not considered packetized.
- * Parse sync is obtained either by providing baseclass with a
- * mask and pattern or a custom @scan_for_sync. When sync is established,
- * @parse_data should invoke @gst_base_video_decoder_add_to_frame and
- * @gst_base_video_decoder_have_frame as appropriate.

- * @see_also: #GstBaseTransform
- *
- * This base class is for video encoders turning raw video into
- * encoded video data.
- *
- * GstBaseVideoEncoder and subclass should cooperate as follows.
- * <orderedlist>
- * <listitem>
- * <itemizedlist><title>Configuration</title>
- * <listitem><para>
- * Initially, GstBaseVideoEncoder calls @start when the encoder element
- * is activated, which allows subclass to perform any global setup.
- * </para></listitem>
- * <listitem><para>
- * GstBaseVideoEncoder calls @set_format to inform subclass of the format
- * of input video data that it is about to receive. Subclass should
- * setup for encoding and configure base class as appropriate
- * (e.g. latency). While unlikely, it might be called more than once,
- * if changing input parameters require reconfiguration. Baseclass
- * will ensure that processing of current configuration is finished.
- * </para></listitem>
- * <listitem><para>
- * GstBaseVideoEncoder calls @stop at end of all processing.
- * </para></listitem>
- * </itemizedlist>
- * </listitem>
- * <listitem>
- * <itemizedlist>
- * <title>Data processing</title>
- * <listitem><para>
- * Base class collects input data and metadata into a frame and hands
- * this to subclass' @handle_frame.
- * </para></listitem>
- * <listitem><para>
- * If codec processing results in encoded data, subclass should call
- * @gst_base_video_encoder_finish_frame to have encoded data pushed
- * downstream.
- * </para></listitem>
- * <listitem><para>
- * If implemented, baseclass calls subclass @shape_output which then sends
- * data downstream in desired form. Otherwise, it is sent as-is.
- * </para></listitem>
- * <listitem><para>
- * GstBaseVideoEncoderClass will handle both srcpad and sinkpad events.
- * Sink events will be passed to subclass if @event callback has been
- * provided.
- * </para></listitem>
- * </itemizedlist>
- * </listitem>
- * <listitem>
- * <itemizedlist><title>Shutdown phase</title>
- * <listitem><para>
- * GstBaseVideoEncoder class calls @stop to inform the subclass that data
- * parsing will be stopped.
- * </para></listitem>
- * </itemizedlist>
- * </listitem>
- * </orderedlist>
- *
- * Subclass is responsible for providing pad template caps for
- * source and sink pads. The pads need to be named "sink" and "src". It should
- * also be able to provide fixed src pad caps in @getcaps by the time it calls
- * @gst_base_video_encoder_finish_frame.
- *
- * Things that subclass need to take care of:
- * <itemizedlist>
- * <listitem><para>Provide pad templates</para></listitem>
- * <listitem><para>
- * Provide source pad caps before pushing the first buffer
- * </para></listitem>
- * <listitem><para>
- * Accept data in @handle_frame and provide encoded results to
- * @gst_base_video_encoder_finish_frame.
