/**
 * SECTION:mixvideoconfigparams
 * @short_description: MI-X Video Configuration Parameter Base Object
 * @include: mixvideoconfigparams.h
 *
 * <para>
 * A base object of MI-X video configuration parameter objects.
 * </para> 
 * <para>
 * The derived MixVideoConfigParams object is created by the MMF/App
 * and provided in the MixVideo mix_video_configure() function. The get and set
 * methods for the properties will be available for the caller to set and get information at
 * configuration time. It will also be created by MixVideo and returned from the
 * mix_video_get_config() function, whereupon the MMF/App can get the get methods to
 * obtain current configuration information.
 * </para> 
 * <para>
 * There are decode mode objects (for example, MixVideoConfigParamsDec) and encode
 * mode objects (for example, MixVideoConfigParamsEnc). Each of these types is refined
 * further with media specific objects. The application should create the correct type of
 * object to match the media format of the stream to be handled, e.g. if the media
 * format of the stream to be decoded is H.264, the application would create a
 * MixVideoConfigParamsDecH264 object for the mix_video_configure() call.
 * </para>
