Hi,
Simply convert the codecNumeric value from decimal to hexadecimal, then convert each byte (2 hex characters) to ASCII characters, disregarding the trailing 00’s. The first character will be ‘V’ for video and ‘A’ for audio. The rest of the characters will represent the codec.
Examples:
6217274493967007744 (decimal) = 5648323634000000 (hexadecimal) = VH264 = Video H264 codec
4702111241970122752 (decimal) = 4141414300000000 (hexadecimal) = AAAC = Audio AAC codec
Cheers,
Don
