Recently AVPro was updated so that Quest users could watch RTSP streams. I was able to confirm this today, but there is a problem.
For TCP RTSP streams, PC users must use rtspt:// format URLs. However, it would appear that Quest users only support rtsp:// URLs.
Quest should either support rtspt:// format URLs (with a simple string replacement to rtsp:// if necessary), or PC should default to TCP-rtsp when using rtsp://.
This is a world where I tested that rtspt:// streams work, but only on PC, and rtsp:// streams work, but only on Quest: https://vrchat.com/home/world/wrld_2745cae5-eecc-44c4-8de7-1ece6a06bc05
