[FFmpeg-user] FFprobe should not return a duration if the file is a JPEG picture

[August Johansson]

Hi,
I am a writing a software that scripts against the FFprobe binary. My
software expects that FFprobe returns N/A as a duration for picture files
and the duration if the file actually is video or audio file.
However I have recently found that when FFprobe is on a JPEG picture file,
it returns 00:00:00.04 as a duration.
I consider this a bug and something that should be fixed.
Thanks for reading
