I investigated the integrity of some *.avi video files with a ffmpeg command
like
ffmpeg -loglevel warning -i -f null -
Most of them are correct but some of them show various errors:
1.) [ac3 @ 02a80800] frame sync error
Error while decoding stream #0:1: Invalid data found when p
When I try
$ ffmpeg -ss 0 -lowres 1 -i video.mxf -i audio.mxf -c copy -f nut - | ffplay -
or
$ ffmpeg -ss 0 -lowres 1 -i video.mxf -i audio.mxf -c copy -f matroska - |
ffplay -
The video is full res, so the -lowres 1 seems to be ignored when -c copy is
present.
The audio plays fine but the vid
$ ffmpeg -ss 0 -lowres 1 -i video.mxf -i audio.mxf -f matroska -c:a copy -c:v
rawvideo - | ffplay -
pulled the following error
[matroska @ 0x7fb16b000e00] Codec for stream 1 does not use global headers but
container format requires global headers
[matroska @ 0x7fb16b000e00] Raw RGB is not suppo
When I try

The video is full res, so the -lowres 1 seems to be ignored when -c copy is
present.
