[VP9-SVC] - Chrome user's webcam stopped on Firefox

[chainit (Lucas DJ)]

Hello developers,
Currently I have an experience of VP9 support functionality on mediasoup v3 demo interface
I have a situation where the sharer’s camera (chrome) after a while (about 5-30s) is standing on the viewer’s side (firefox).

Reproduce:
Step1: Visit the demo page and start the VP9 support meeting

mediasoup demo

Step2: User1: Join demo with Firefox browser & open camera
Step3: User2: Join demo with Chrome browser & open camera
Step4: Observe the webcam movement between Firefox and Chrome (after a while you will see the user’s webcam on the chrome side will be stuck on the Firefox side of the browser)

I don’t know what is the cause of this error, in core mediasoup or because the encode/decode between Firefox & Chrome is out of sync. I am using Firefox version 103.0.1 (64-bit) & Chrome version 104.0.5112.81 (64-bit)

Looking forward to receiving your feedback.
Thank you

This type of issue is mentioned here as well a few days ago:

Video freeze in Firefox, mac m1

Reproduce steps: Open demo mediasoup in ff last version on mac m1 https://v3demo.mediasoup.org/ Open demo in different browser with same roomId what was in 1 step Leave window ff and open different(no matter what window exactly) After a while video in ff will freeze In common I catch that bug, but time to time video working properly I’ve checked all params. And as I see consumer is started, but consumer don’t get packets from server. Server send packet normally Audio is working well
