I am new to opencv and python and not really sure ehere to address this issue... When I gray-scale a mp4 teststream I end up with a grayed video but it is shorter than the original and i see it multiple (9) times in the viewing frame.
To test my code I used cv2.COLOR_RGB2YUV and that woked fine
This works fine 10 sec.video as one image in the viewing frame
new_clip = test_clip.fl_image(lambda x: cv2.cvtColor(x, cv2.COLOR_RGB2YUV))
This fails only 3 sec. output and 9 tiles of the same content in the viewing frame
new_clip = test_clip.fl_image(lambda x: cv2.cvtColor(x, cv2.COLOR_RGB2GRAY))
Best regards NIls
