The problem is not reproducible this way because you provide -f. But I
cannot provide -f in my situation because I have no idea what the format
of the input file is. I just have file with random extension but it can be
anything from mp4 to ogv.
If I run my commands with -f e.g.
{{{
ffprobe -f mjpeg d:\temp\MJPEG.avi
}}}
or
{{{
ffprobe -f mjpeg d:\temp\MJPEG
}}}
(note: MJPEG.avi and MJPEG are the same files, just renamed, and they are
actually MJPEG)
everything works perfectly.
The thing I'm complaining here about is that ffprobe/ffplay/ffmpeg does
not detect MJPEG format correctly when file is without extension (or with
random extension) and misdetects format as AVI when the extension is .avi.
Regarding ticket #2541 - I'm not sure if this is duplicate. I don't
understand completely what #2541 is about.
