[FFmpeg-user] Transport Stream (.ts) with ac3 audio

[Michael Thaler]

if I check the .ts files with FFprobe, I get this for the ac3 stream:

Created by FFmpeg:
codec_tag_string=[129][0][0][0]
codec_tag=0x0081


Created by others:
codec_tag_string=[6][0][0][0]
codec_tag=0x0006


My question is, can I set codec_tag and codec_tag_string by FFmpeg with -metadata  ?

Thanks in advance

Michael
