Video Track Optimisation in Conference

[burak-58]

• Define different quality levels (No Video, 180p, 360p, 720p) for publishers. No video case may cause issue in recording.
• Send layout info for all participants to AMS in conference
• Determine quality level for a publisher according to the layout info those are got from viewers. For example if some publisher is not pinned in any other participant's layout then decide that quality level for him should be no video or 180p
• Inform the publisher about the determined quality level
• Change WebRTC media constraints level dynamically for the publisher
