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
还请查看来自OpenCV教程的此链接，以获取有关可用于您的平台的FourCC代码的更多详细信息.
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.
