H.264 inside MP4/MOV is not concatenatable. The concat demuxer can make it so, you need to use the {{{-auto_convert}}} option to enable it. do you tried to concatinate files from attachments whith this command ?
1. i think the problem keeps in streams positions 2. in mov files are same stream positions, concat procces will be successful. So, i used command ffmpeg -re -loglevel debug -report -y -auto_convert 1 -f concat -i /Users/pc/movies/mylist.txt -c copy -f flv test_bug_concat.flv the same result.
