推荐答案

我知道这已经很老了，但是我会把自己的经验加到这堵墙上，以防将来有人遇到这个问题.

I know this is quite old, but I'll add my experience to this wall incase future people have this problem.

我在使用PIM1 fourCC进行输出时遇到了此问题-从

I encountered this using the PIM1 fourCC for output - my problem was solved when I changed from

video_output = cvCreateVideoWriter("disparity_output.mov", CV_FOURCC('P', 'I', 'M', '1'), 32, size, 0);

收件人:

video_output = cvCreateVideoWriter("disparity_output.mkv", CV_FOURCC('P', 'I', 'M', '1'), 32, size, 0);

将输出路径更改为具有可接受的文件扩展名(或者我假设是).不确定是否有帮助，但是对我有用.

changing the output path to have a file extension that was acceptable (or so I assume). Not sure if it helps, but it worked for me.
