CLI video file query tool?

[stuinzuri]

I'm looking for a command line tool to query video files for information on their tracks, codecs, lengths, etc. My immediate concern is MP4 files, but want to expand to others later.

I had been using mp4info (part of the seemingly defunct mpeg4ip project) but getting that running on my target installations has been...problematic. E.g.:

manoa:Movies stu$ mp4info cochlear.mp4
mp4info version 1.5.0.1
cochlear.mp4:
Track Type Info
1 video H264 Baseline@2.1, 2676.760 secs, 811 kbps, 496x280 @ 25.000000 fps
2 audio MPEG-4 AAC LC, 2676.703 secs, 0 kbps, 44100 Hz
Metadata Tool: Lavf52.38.0
manoa:Movies stu$

ffmpeg does not, to my knowledge, have a query mode. (If it does, please edumacate me.)

The output will be consumed by my own code.

ffmpeg -i file

Not a very detailed report but...

Cool. Mediainfo looks like what I want, but it broken on Snow Leopard (along with another zillion projects.)


ffmpeg -i file

Yea...but what bugs me there is ffmpeg does not exit 0, which I'd like for correctness's sake. More info is desirable too. But thanks anyway.

You should talk to Zenitram (http://forum.doom9.org/member.php?u=16626) about the issue...

True, but ffmpeg shouldn't return 0 in this case, it didn't finish correctly. :)

Since I want to do this programatically, that makes error detection difficult and fuzzy. What is the difference between a successful completion, and a true error condition? (Like path errors, etc.)
