Track-Based SFU Video Conference
This is a recent conference solution in AMS. It works with WebRTC tracks instead of streams. Users can find more about multitrack streaming in this blog post.

When a participant joins a room, he/she sends a join request to AMS for the room.
AMS responds with the stream ID(stream_id) for the participant.
He/She starts to publish a WebRTC stream with his stream ID(stream_id).
He/She sends only one WebRTC play request for the room ID.
AMS sends the notification in the app for the newly joined/left participants. (Used for UI).
The calling leave method is enough to leave the room and leave the meeting.
