ffmpeg的不是有空格的文件名工作 [英] ffmpeg not working with filenames that have whitespace

问题描述

我使用FFMPEG来衡量存储在Amazon S3的桶的视频时长。

I'm using FFMPEG to measure the duration of videos stored in an Amazon S3 Bucket.

我看过FFmpeg的文档，并且他们明确规定所有的空白和特殊字符需要转义，为了FFMPEG，妥善处理中：

I've read the FFMPEG docs, and they explicitly state that all whitespace and special characters need to be escaped, in order for FFMPEG to handle them properly:

请参阅文档2.1和2.1.1： https://ffmpeg.org/ffmpeg-utils.html

See docs 2.1 and 2.1.1: https://ffmpeg.org/ffmpeg-utils.html

然而，随着文件的文件名包含空格打交道时，FFMPEG无法呈现的结果。

However, when dealing with files whose filenames contain whitespace, ffmpeg fails to render a result.

我试过以下，但没有成功。

I've tried the following, with no success

ffmpeg -i "http://s3.mybucketname.com/videos/my\ video\ file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
ffmpeg -i "http://s3.mybucketname.com/videos/my video file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
ffmpeg -i "http://s3.mybucketname.com/videos/my'\' video'\' file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d
ffmpeg -i "http://s3.mybucketname.com/videos/my\ video\ file.mov" 2>&1 | grep Duration | awk '{print $2}' | tr -d

不过，如果我在文件名中去掉空白 - 一切都很好，并返回视频的持续时间。

However, if I strip out the whitespace in the filename – all is well, and the duration of the video is returned.

任何帮助AP preciated！

Any help is appreciated!

推荐答案

如果你碰巧有您的文件名称空间，只是引用他们：

If you happen to have spaces in your file name, just quote them:

ffmpeg -i "my video file.mov"

在一个URL，一个空间不能有。最可能的是你有更换每一个空间 20％，使您获得：

In a URL, a space cannot be there. Most probably you have to replace every single space with a %20, so that you get:

ffmpeg -i http://myurl.com/my%20video%20file.mov
