- some participants have their video always muted (and their camera is on and working for Hangouts, for example).
- other participants start the same (video muted), but after 3-5 minutes the video is automatically unmuted.
- if we do a layout change (using fs_cli), all participants (having video muted or unmuted at that moment) go to muted video for the rest of the conference.

What is the reason for fs to automatically mute the video? Is this expected or does it look like a bug? Can this behaviour be tuned or disconnected?

Thank you,
