``V4L2_CID_MPEG_VIDEO_AU_DELIMITER (boolean)``

    If enabled then, AUD (Access Unit Delimiter) NALUs will be generated.

    That could be useful to find the start of a frame without having to

    fully parse each NALU. Applicable to the H264 and HEVC encoders.



``V4L2_CID_MPEG_VIDEO_H264_VUI_SAR_ENABLE (boolean)``

    Enable writing sample aspect ratio in the Video Usability

    Information. Applicable to the H264 encoder.
