[meta-intel] [PATCH] gstreamer-vaapi: upgrade to 0.5.9
Ross Burton
ross.burton at intel.com
Tue Jan 20 04:10:09 PST 2015
Upgrade to 0.5.9, and drop the patches that were backported from git.
Also disable the built-in libvpx as it doesn't cross-compile. This means that
WebM decoding isn't supported.

- * 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>
