Comment (by artem):
I have a similar problem in Windows with .. being ignored by the concat
demuxer.
Source video file: c:\tmp\ffmpeg_bug_8813\GOPR0083.MP4
c:\tmp\ffmpeg_bug_8813\subdir\myconcatlist.txt contains:
{{{
file '../GOPR0083.MP4'
}}}
Executed in c:\tmp\ffmpeg_bug_8813\subdir

If I move the source file from c:\tmp\ffmpeg_bug_8813\ to
c:\tmp\ffmpeg_bug_8813\subdir then the same command executed in subdir
works fine even without changing myconcatlist.txt (i.e. "../" prefix is
still there):
