This works well if a Youtube URL disappears or is replaced with the YT error
message about copyright.
But whenever the video stalls and just continuously displays one single image
for minutes on end the test above does not detect it.
So is there a way to check if a video is static and generate an error in that
Something like:
ffmpeg -i input_url -checkstaticvideo <maxstatictime>

Is this possible?
