public bool get_profile_flags_level (uint8 codecs_data, uint len, uint8 profile, uint8 flags, uint8 level)

Parses profile, flags, and level from a H264 AVCC extradata/sequence_header.

These are most commonly retrieved from a video/x-h264 caps with a codec_data buffer. The format of H264 AVCC extradata/sequence_header is documented in the ITU-T H.264 specification section 7.3.2.1.1 as well as in ISO/IEC 14496-15 section 5.3.3.1.2.

Parameters:

len

lenth of codec_data

profile

return location for h264 profile_idc or null

flags

return location for h264 constraint set flags or null

level

return location h264 level_idc or null

codec_data

H264 AVCC extradata
