Wrong frame position when using the OpenCV 4.3.0
Hi, I encountered a problem when using OpenCV 4.3.0.
When I use
video_capture.set(CAP_PROP_POS_FRAMES, frame_index);,
if the frame is a B-frame, there will be a problem.
It seems that we cannot frame_index as a B-frame. But there is no function to detect whether a frame is a B-frame.
Does anybody know the solution to this problem? Seeking to the B-frame or avoid seeking to B-frame?
