++ * SECTION:gstvideoencoder
++ * @short_description: Base class for video encoders
++ * @see_also:
++ *
++ * This base class is for video encoders turning raw video into
++ * encoded video data.
++ *
++ * GstVideoEncoder and subclass should cooperate as follows.
++ * <orderedlist>
++ * <listitem>
++ *   <itemizedlist><title>Configuration</title>
++ *   <listitem><para>
++ *     Initially, GstVideoEncoder calls @start when the encoder element
++ *     is activated, which allows subclass to perform any global setup.
++ *   </para></listitem>
++ *   <listitem><para>
++ *     GstVideoEncoder 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>
++ *     GstVideoEncoder 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_video_encoder_finish_frame to have encoded data pushed
++ *       downstream.
++ *     </para></listitem>
++ *     <listitem><para>
++ *       If implemented, baseclass calls subclass @pre_push just prior to
++ *       pushing to allow subclasses to modify some metadata on the buffer.
++ *       If it returns GST_FLOW_OK, the buffer is pushed downstream.
++ *     </para></listitem>
++ *     <listitem><para>
++ *       GstVideoEncoderClass 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>
++ *     GstVideoEncoder 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_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_video_encoder_finish_frame.
++ *   </para></listitem>
++ * </itemizedlist>
