you can utilize this script acompanied from mplayer ;)


script: midentify
---------------------------------------------------------------
#!/bin/sh
#
# This is a wrapper around the -identify functionality.
# It is supposed to escape the output properly, so it can be easily
# used in shellscripts by 'eval'ing the output of this script.

if [ -z "$1" ]; then
        echo "Usage: midentify <file> [<file> ...]"
        exit 1
fi

mplayer -vo null -ao null -frames 0 -identify "$@" 2>/dev/null |
        sed -ne '/^ID_/ {
