如何从linux命令行获取视频文件的分辨率(宽度和高度)?

I've been digging through the mplayer/mencoder and ffmpeg documentation and I can't seem to come up with anything. I'm not especially picky as to the output format as I can use a regular expression to pull it out, I just can't seem to get the data in the first place.

我一直在查阅mplayer/mencoder和ffmpeg文档，但似乎什么都想不出来。对于输出格式，我不是特别挑剔，因为我可以使用正则表达式来提取它，我只是不能首先获得数据。

#1

MediaInfo has a command line version and provides the dimensions together with tons of other information.

MediaInfo有一个命令行版本，并提供维度和大量其他信息。

Use ffprobe (part of FFmpeg toolkit)

使用ffprobe (FFmpeg工具包的一部分)

example:

例子:

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

output:

输出:

$  ./midentify.sh /data/myvid.flv 
ID_VIDEO_ID=0

To return only the Width and Height mediainfo is an excellent tool.

只返回宽度和高度是一个很好的工具。

mediainfo --Inform="Video;%Width%" Videofile && mediainfo --Inform="Video;%Height%" Videofile will do exactly that, no more, no less, for a vast array of supported video files.

mediainfo—Inform=“Video;%Width%”Videofile && & mediainfo—Inform=“Video;%Height%”Videofile将对大量受支持的视频文件执行同样的操作。

There is a long list of useful Inform= parameters which you can obtain with the command mediainfo --Info-Parameters

有一长串有用的Inform=参数列表，您可以通过命令mediainfo -Info-Parameters获得这些参数

If you want the output in standard WidthXHeight format use Width=$(mediainfo --Inform="Video;%Width%" Video.File)&& Height=$(mediainfo --Inform="Video;%Height%" Video.File)&&echo $Width"X"$Height

如果您想要以标准的WidthXHeight格式输出，请使用Width=$(mediainfo—Inform=“Video;%Width%”Video. file)和Height=$(mediainfo—Inform=“Video;%Height%”Video.File)并回传$Width“X”$Height

There's a bash script here that you could easily modify to meet your needs.

这里有一个bash脚本，您可以轻松修改它以满足您的需求。

If you are just interested in the resolution:

如果你只是对决议感兴趣:

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

It works also on Windows. This is running right now on my PC to build an index of all files:

它也适用于Windows。这是现在在我的电脑上运行，建立一个索引的所有文件:

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

Here's an "almost-one-liner" I've concocted around ffprobe for exactly this purpose. Works pretty well for me both on Linux and MacOS.

这是我围绕ffprobe来编造的一个“几乎是一行的词”，就是为了这个目的。我在Linux和MacOS上都做得很好。

#!/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/"

The good ol' "file" utility will often get the dimensions of a video file.

好的ol的“文件”工具通常会得到视频文件的尺寸。
