如何从linux命令行获得video文件的分辨率(宽度和高度)?

我一直在挖掘mplayer / mencoder和ffmpeg文档,我似乎无法提供任何东西 。 我对输出格式不是特别挑剔,因为我可以使用正则expression式将其拉出,我似乎无法获取数据。

MediaInfo有一个命令行版本,并提供了大量的其他信息的维度。

使用ffprobe (FFmpeg工具包的一部分)

例:

ffprobe -v quiet -print_format json -show_format -show_streams ~/Movies/big_buck_bunny_720p_5mb.mp4 

输出:

使用mediainfo

时间总结

 exiftool real 0m0.089s user 0m0.081s sys 0m0.008s mplayer real 0m0.050s user 0m0.034s sys 0m0.017s ffprobe/ffmpeg real 0m0.017s user 0m0.011s sys 0m0.007s mediainfo real 0m0.029s user 0m0.025s sys 0m0.004s 

YMMV,但是ffprobe是mediainfo最快的,然后是mplayer,最后是exiftool

 ffprobe < mediainfo < mplayer < exiftool 

使用ffprobe

 $ eval $(ffprobe -v error -of flat=s=_ -select_streams v:0 -show_entries stream=height,width input.mkv) $ size=${streams_stream_0_width}x${streams_stream_0_height} $ echo $size 1280x720 

请参阅FFprobe文档和FFmpeg Wiki:FFprobe提示 。

尝试midentify.sh(MPlayer的源代码树中的TOOLS / midentify.sh)。

它将以可解析的格式显示信息:

 $ ./midentify.sh /data/myvid.flv ID_VIDEO_ID=0 ID_AUDIO_ID=1 ID_FILENAME=/data/myvid.flv ID_DEMUXER=lavfpref ID_VIDEO_FORMAT=VP6F ID_VIDEO_BITRATE=0 ID_VIDEO_WIDTH=640 ID_VIDEO_HEIGHT=480 

[,,,]

如果您只是对分辨率感兴趣,

 ffprobe -v error -of flat=s=_ -select_streams v:0 -show_entries stream=height,width video.mkv 

它也适用于Windows 。 这是在我的电脑上运行,建立所有文件的索引:

 find //Q1207/Film -size +10000k -print -a -exec ./ffprobe.exe -v error -of flat=s=_ -select_streams v:0 -show_entries stream=height,width \{\} \; > //Q1207/Film/index.txt 

返回宽度和高度mediainfo是一个很好的工具。

mediainfo –Inform =“Video;%Width%”Videofile && mediainfo –Inform =“Video;%Height%”对于大量受支持的视频文件 ,Videofile可以做到这一点,不多不少。

有很多有用的Inform=参数,您可以使用命令mediainfo --Info-Parameters获取这些mediainfo --Info-Parameters

如果您希望以标准WidthXHeight格式输出,请使用Width=$(mediainfo --Inform="Video;%Width%" Video.File)&& Height=$(mediainfo --Inform="Video;%Height%" Video.File)&&echo $Width"X"$Height

whiptail:如何将输出重定向到环境变量?

如何连接Bash中的字符串变量?

这是我为了这个目的而编写的一个“差不多一行代码”。 在Linux和MacOS上都适合我。

 #!/bin/bash B='[[:blank:]]' D='[[:digit:]]' ffprobe "$1" 2>&1 \ | grep 'Stream.*Video.*fps' \ | sed "s/^.*$B\($D$D$D*x$D$D$D*\).*$/\1/" 

好的“文件”实用程序通常会获得视频文件的尺寸。
