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)
答案1
您可以使用多个命令来获取该信息:
avprobe
从包装来看libav-tools
还不错。示例输出
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
要添加 Thunar 自定义操作,根据此处的建议,要添加的模拟公式是:
gnome-terminal --window-with-profile=new1 -e "avprobe %f"
来源:在终端中查看媒体文件信息的命令?(然后,复制)。
而且你还有:
您可以使用 MPlayer 来获取该信息。
$ mplayer -vo null -ao null -identify -frames 0 foo.avi
