从 命令行 工具获取有关视频的信息

问题描述

如何使用 命令行 工具获取有关视频的信息？ (例如视频时长、音频编解码器、比特率等)

最佳方案

您有几个命令可以获取该信息：

avprobe from the package libav-tools is pretty good.

Sample output avprobe somefile.mp4

avprobe version 0.8.4-4:0.8.4-0ubuntu0.12.04.1, Copyright (c) 2007-2012 the Libav developers   built on Nov  6 2012 16:51:33 with gcc 4.6.3 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'somefile.mp4':   Metadata:     major_brand     : avc1     minor_version   : 0     compatible_brands: isomavc1     creation_time   : 2012-08-10 15:01:14   Duration: 00:01:02.55, start: 0.000000, bitrate: 682 kb/s     Stream #0.0(und): Video: h264 (High), yuv420p, 1904x1040 [PAR 1:1 DAR 119:65], 680 kb/s, 19.18 fps, 20 tbr, 20 tbn, 40 tbc     Metadata:     creation_time   : 2012-08-10 15:01:14 

To add to Thunar custom action, in relation to what was suggested here, the analog formula to add would be:

gnome-terminal --window-with-profile=new1 -e "avprobe %f"

你还有：

You can use MPlayer to get that information.

$ mplayer -vo null -ao null -identify -frames 0 foo.avi

次佳方案

有几种方法可以实现这一点。这是三种方法，使用三种不同的实用程序。

使用 exiftool

1. 使用命令 sudo apt-get install libimage-exiftool-perl 安装 libimage-exiftool-perl。

2. 运行 exiftool /path/to/file

3. 你得到的输出类似于：
