/**
 * SECTION:mixvideo
 * @short_description: Object to support a single stream decoding or encoding using hardware accelerated decoder/encoder.
 * @include: mixvideo.h
 *
 * #MixVideo objects are created by the MMF/App and utilized for main MI-X API functionality for video.
 *
 * The MixVideo object handles any of the video formats internally.
 * The App/MMF will pass a MixVideoConfigParamsDecH264/MixVideoConfigParamsDecVC1/
 * MixVideoConfigParamsEncH264/etc object to MixVideo in the mix_video_configure()
 * call. MixVideoInitParams, MixVideoDecodeParams, MixVideoEncodeParams, and
 * MixVideoRenderParams objects will be passed in the mix_video_initialize(),
 * mix_video_decode(), mix_video_encode() and mix_video_render() calls respectively.
 *
 * The application can take the following steps to decode video:
 * <itemizedlist>
 * <listitem>Create a mix_video object using mix_video_new()</listitem>
 * <listitem>Initialize the object using mix_video_initialize()</listitem>
 * <listitem>Configure the stream using mix_video_configure()</listitem>
 * <listitem>Decode frames using mix_video_decode()</listitem>
 * <listitem>Retrieve the decoded frames using mix_video_get_frame(). The decoded frames can be retrieved in decode order or display order.</listitem>
 * <listitem>At the presentation time, using the timestamp provided with the decoded frame, render the frame to an X11 Window using mix_video_render(). The frame can be retained for redrawing until the next frame is retrieved.</listitem>
 * <listitem>When the frame is no longer needed for redrawing, release the frame using mix_video_release_frame().</listitem>
 * </itemizedlist>
 *
 * For encoding, the application can take the following steps to encode video:
 * <itemizedlist>
 * <listitem>Create a mix_video object using mix_video_new()</listitem>
 * <listitem>Initialize the object using mix_video_initialize()</listitem>
 * <listitem>Configure the stream using mix_video_configure()</listitem>
 * <listitem>Encode frames using mix_video_encode()</listitem>
 * <listitem>Use the encoded data buffers as desired; for example, forward to a muxing component for saving to a file.</listitem>
 * <listitem>Retrieve the uncompressed frames for display using mix_video_get_frame().</listitem>
 * <listitem>At the presentation time, using the timestamp provided with the decoded frame, render the frame to an X11 Window using mix_video_render(). For encode, the frame should not be retained for redrawing after the initial rendering, due to resource limitations.</listitem>
 * <listitem>Release the frame using mix_video_release_frame().</listitem>
 * </itemizedlist>
