//
// |video_codec|: The video codec used in the media content.
// |profile|: The profile in the context of |video_codec|.  It should be set to
//            -1 when it is unknown or not applicable.
// |level|: The level in the context of |video_codec|.  It should be set to -1
//          when it is unknown or not applicable.
// |bit_depth|: The color bit depth of the video.  It should be set to 8 for SDR
//              videos, and set to 10 or 12 for HDR videos.
// |primary_id|: The colour primaries of the video.  See definition for
//               |SbMediaPrimaryId| in `media.h` for more details.  It should be
//               set to |kSbMediaPrimaryIdUnspecified| when it is unknown.

//                should be set to |kSbMediaTransferIdUnspecified| when it is

//                set to |kSbMediaMatrixIdUnspecified| when it is unknown.
// |frame_width|: The frame width of the media content.  When set to 0, it
//                indicates that the frame width shouldn't be considered.
// |frame_height|: The frame height of the media content.  When set to 0, it
//                indicates that the frame height shouldn't be considered.
// |bitrate|: The bitrate of the media content.  When set to 0, it indicates
//            that the bitrate shouldn't be considered.
// |fps|: The number of frames per second in the media content.  When set to 0,
//        it indicates that the fps shouldn't be considered.
// |decode_to_texture_required|: Whether or not the resulting video frames can
//                               be decoded and used as textures by the GPU.
