什么是python OpenCV中mp4视频的编解码器 [英] what is the codec for mp4 videos in python OpenCV

问题描述

fourcc = cv2.cv.CV_FOURCC(*'XVID')

以上行用于avi视频.以同样的方式，我们在Ubuntu中为mp4视频使用哪种编解码器?

The above line is used for avi video. In the same fashion, which codec do we use for mp4 videos in Ubuntu?

推荐答案

编解码器为H.264.

The codec is H.264.

其中一个应该为您工作:

One of these should work for you:

fourcc = cv2.cv.CV_FOURCC(*'H264')
#or 
#fourcc = cv2.cv.CV_FOURCC(*'X264')

但是，我应该警告您，您可能需要安装ffmpeg和x264库，因此由于您在Ubuntu中，请尝试在终端中执行以下命令:

However, I should warn you that you'll probably need to have ffmpeg and the x264 libraries installed so since you are in Ubuntu, try doing this command in the terminal:

sudo apt-get install ffmpeg x264 libx264-dev

还请查看

Also, check out this link from OpenCV tutorials for more details as to the kinds of FourCC codes available for your platform.

在上面的链接中，您说X264是您应该使用的FourCC代码，但是请在它们之间进行切换，直到您可以使用它为止.

In the above link, it says X264 is the FourCC code you should use, but switch between them until you get it to work.
