Convert autoplay videos with sound to click-to-play, keep silent autoplay videos looping, show thumbnail, conditional controls
This script makes it so "soundless autoplay" videos are displayed more similarily to normal videos. Like they were before the recent change. Specifically it will do this: When a video with sound is posted as "soundless autoplay", this script will detect that, pause it, enable video controls, set the time to 0.01 (to show a thumbnail), remove the "loop" and unmute it. Now you'll see a paused video with a black play button, and once you click it, it plays like just any other normal video. That way you see instantly what is and isn't a video with sound. If a video without sound is posted as "soundless autoplay" nothing will change, as it is essentially a GIF anyways.
