You've got a few problems, according to our automated analyzer:
OBS (Open Broadcaster Software) is free and open source software for video recording and live streaming. Stream to Twitch, YouTube and many other providers or record your own videos with high quality H264 / AAC encoding.

See what you can do about those.
Also, reading it manually says you're using AV1. I'd stick with h.264 until you get it working. It's not as efficient (bits per quality), but it's been universally supported almost forever now. Everyone knows how to read that. AV1 just came out recently, so not everyone knows what to do with it yet.
H.265 is a licensing mess, so not everyone supports it either. Looks like someone tried to profit too much from that one, and killed it.
