Giving it either a long (2.5hr) video, or a non-youtube URL (e.g. an invidious link) appears to leave it spinning forever - no error message.

If you don't mind, could you share an example of such long video? I'd love to debug it.

As for non-Youtube URL: I indeed do not handle that error right now :D. Thanks so much for bringing it up!

This is the 2.5hr video i tried: https://www.youtube.com/watch?v=JGIGA8taN-M

This 1hr video works (but I note you don't seem to be caching the output?) https://www.youtube.com/watch?v=0s9fpFPAC94

This <1hr video seemed to crash the system: https://www.youtube.com/watch?v=VV949D8AUKU

That one works for me.
