Chrome and Edge works fine but Firefox gives "codecs not supported by client"

Question

Please help. The media router works in routing video streams via WebRTC to Chrome and Edge browsers but when I use Firefox (latest version 126), I get "codecs not supported by client" error.

What IS the codec you're streaming?
If it's H264 (which is likely, given how narrow the codec support for WebRTC is) then it should only be an issue on Android Firefox, but more details would help.

You can type "about:support" into Firefox's address bar and scroll down to the Media table to see which codecs your Firefox supports, and maybe we can find some problem there

This is what I got, I can't see there is any problem here if H264 is what WebRTC requires. BTW, I use the browser client code https://github.com/bluenviron/mediamtx/blob/main/internal/servers/webrtc/read_index.html as reference in my Angular code. Works perfectly fine in Chrome.
