Using the FFMPEG integration from the latest expyfun release, I am able to play MP4 videos at the size of the example video in simple_video.py: window_size = (720, 480). Playing at a smaller screen size and changing the aspect ratio (e.g. with window_size = (688, 387), which is 16:9) are both fine, but making the video window much larger -- or attempting to play it full screen -- causes problems on the two Windows machines I've tested.
As the screen size is increased to an intermediate level, e.g. (1050, 700) px, playback starts getting choppy, with what looks like dropped frames at the beginning. I can play the included example-video.mp4 up to full screen, but with similar issues. Trying to play other MP4 files at or near full screen leads to crashing, usually on the second ec.flip() call, with the error traceback below.
Curious if anyone has tried increasing the video window size on their machines and encountered similar issues.
