Some additional info: it happens after muting the video and then unmuting it after a certain time. I.e. if I mute my video and unmute it in let's say 30 seconds, no one will see my video feed (it looks as if there is no video), meanwhile, I'm getting these in the SFU from Pion:

Not sure why so many of them though. I just have 2 participants in a conference and only mute the video of one of them, then unmute after some time.

I wonder if matrix-org/matrix-js-sdk#3091 will make a difference here
