Re: getting video specs using ffmpeg

ffprobe. It comes with ffmpeg, just like ffplay.

ffprobe /[path/to/your/video.mov

For extra laffs you can redirect the stderr to stdout and pipe it to grep and/or sed if you're using it as part of a larger application, eg:

ffprobe ~/mymovie.mov 2>&1 |grep Duration|sed "s/[A-z :]*\([0-9:.]*\).*/\1/"
00:00:50.66

The sed example above uses OSX's curious sed implementation, you may not need to escape the brackets.
