when I read some video in this way vr = VideoReader(path)，I get “h264 mmco: unref short failure”，how could I solve it？当我按照上面这个方法读视频的时候，会出现提示 h264 mmco: unref short failure，我该如何解决它

我也遇到同样的问题，请问你们的program crash了吗？我发现我这边读取并没有crash，获得的tensor看上去也是正常的（我visualize了一下）

我现在的做法是 python main.py 2> log.err，然后尽量把有用的信息都写到stdout上

请问有人解决了么？

This is because the code calls VideoCapture.set(cv2.CAP_PROP_POS_FRAMES, frame_num) which seeks the video to the given frame_num. The mmco: unref short failure is caused by OpenCV for OpenCV doesn’t do seeking too well.

I just find why it throws, but don't know how to fix it. This might have relationships with the key-frames of a video, so I'm trying to use PyAV
