mediainfo - ubuntu取得多媒體資訊的控制台工具？

Question

Ubuntu 12.04，
我查到有 mediainfo 可以獲取多媒體信息。
請問還有其它方便的可以獲取音視頻的編碼方式的工具麼~

FFmpeg 2.1 與 gstreamer 1.3 在不編碼的情況下可以有什麼命令獲取？

Answer 1

我一直在用的腳本：

>>> 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 "" ]; 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
                        }'

Answer 2

三個工具都可以：

MP4Box -info video.mp4

ffmpeg -i video.mp4

mediainfo video.mp4
