This is very nice and it works! Using a chromium version capable of playing H265 (https://github.com/RobRich999/Chromium_Clang/releases) and a nightly go2rtc.

Switched a noname 4k camera, one Reolink and 5 Hikvision cameras to H265 (adding Opus Audio when needed). And every Stream plays with RTC!

All ok. Additional tests are fine.
