Hi all,
This is slightly OT for the group, but I hope someone can tell me.
I have thousands of large AVI files and I want a quick way to determine
from the command line whether their audio is stereo, 5.1, etc.
I've read about ffmpeg and haven't seen anything jumping out at me, and
it's hard to pick the right search keywords to find relevant pages on
Google.
Anyone know a trick to get this info? Currently I can do it by
right-clicking on the file and viewing its properties, but there *has*
to be a better way...
maybe "mplayer -frame 0 -identify myfile.avi" ?
Cheers,

Thanks for your advice. Unfortunately this seems to require a graphical
machine, but I'm trying to run this on a headless fileserver that has
all my media.
[jonathan@zeus ~]$ mplayer -frame 0 -identify movie.avi
Creating config file: /home/jonathan/.mplayer/config
Unknown option on the command line: -frame
Error parsing option on the command line: -frame

Any other ideas?
It's a small commandline-tool to extract information from any media file
which ffmpeg can read. For some example output see:
