在基于Debian的系统上(但大概其他发行版也将mediainfo
在其存储库中提供):
$ sudo apt-get install mediainfo
$ mediainfo foo.mp4
那会散发出很多信息。例如,要获取长度,分辨率,编解码器和尺寸,请使用:
$ $ mediainfo "The Blues Brothers.mp4" | grep -E 'Duration|Format |Width|Height' | sort | uniq
Duration : 2h 27mn
Format : AAC
Format : AVC

您可以使用exiftool。要安装它,请运行:
sudo apt-get install libimage-exiftool-perl
然后从mp4文件中获取元数据:
exiftool video_file.mp4 > medatata.txt
保存在文件中的输出应如下所示:
