Hi I have a bunch of video files which are either mkv or mp4. Some play, some dont. Have read that the header should describe
H264/MPEG-4/AVC profile at Level 4.1 or below. EG 5.1 is not compliant.
Well the profile is 4.1 or below, but the header in errant files may be compressed which I understand breaks player compatibility.
Can anyone suggest preferably a Linux/Ubuntu remux method (not recode) and if so what settings are known to work?
I have tried mkvmerge with no success, but possibly wrong settings.
Thanks for any info.
Alistair.
