ubuntu获取多媒体信息的控制台工具？

Ubuntu 12.04，
我查到有 mediainfo 可以获取多媒体信息。
请问还有其它方便的可以获取音视频的编码方式的工具么~

FFmpeg 2.1 与 gstreamer 1.3 在不编码的情况下可以有什么命令获取？

三个工具都可以：

MP4Box -info video.mp4

ffmpeg -i video.mp4

mediainfo video.mp4

我一直在用的脚本：

>>> cat =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 "$@" 2>/dev/null |
        sed -ne '/^ID_/ {
                          s/[]()|&;<>`'"'"'\\!$" []/\\&/g;p
                        }'
