When a file formats have multiple file type descriptors testing to see if the file is usable for transcoding, a problem arises for how to match against ffmpeg's formats. For example, my mov has the following descriptor

Input #0, mov,mp4,m4a,3gp, from '/Users/arthur/Movies/iShowU HD/ISUHD.mov'

The codec that will decode it is

 D  mov,mp4,m4a,3gp,3g2,mj2 QuickTime/MPEG4/Motion JPEG 2000 format

The issue is that both lists of formats need to be broken apart and addressed as single items. The question is if this is a problem.

I would just consider it as an mov since Quicktime is a container for different codecs. In my opinion, the more important things are the audio and video codecs inside the file formats.

I'm somewhat surprised that ffmpeg would return "mov,mp4,m4a,3gp" as the file format instead of "mov,mp4,m4a,3gp,3g2,mj2"
since it is more or less the same thing for all intensive purposes.
