I haven't specifically seen this issue reported, but I'm using OBS Studio to stream & record our Roll20 sessions. I haven't tried this when *just* streaming, but I see this behaviour when recording... When NOT recording, webcams work fine, I can see mine, others can see mine, I can see theirs. When recording, I can see mine, but not theirs. If I disable broadcasting my cam via Roll20, I can then see theirs, but I can't be broadcasting and receiving at the same time while OBS is recording. If I stop recording, the cams all work. I do NOT have my cam set as a video capture source in OBS, I have it all via Roll20. Has anyone come across this issue? I am using Firefox. I cannot use Chrome because in order to use Window Capture with OBS so I can mask the cams, I need to turn off hardware acceleration in Chrome, which makes Roll20 run like molasses, so stuck with Firefox.
