I've seen many strange mp4s and webms floating around various discord communities. Some crash your client at a fitting moment in the video, some appear to be thousands of hours long, some appear to be seconds long but are actually hours long, some even loop! somehow.

Do you still have copies of them? Could you send them to jtunney@gmail.com? I'd like to setup a web page hosting MPEG torture tests, since there doesn't appear to be one already. This is actually a very common practice for things like RFCs written for text-based protocols. We should ideally have more accessible information online that helps video software authors to harden their implementations against these sorts of busy beaver attacks.
I even saw videos that play something entirely different the second time you play it!
