Installed opencv from PIP (python 3.8) and just cant write any video properly. Using this general constructor pattern: writer = cv.VideoWriter('myvideo.avi',cv.VideoWriter_fourcc('m','j','p','g'),25,(h,w)) And trying many different codecs (divx, mp4v, avc1...) - none of them works. Just getting an unreadable file 'myvideo.avi' that weights just a few KB.

The irony is that if I write the video using opencv c++ code (been using this example), it works perfect.
