Hello,
I have following requirements for multi-user video conference:
1. One Teacher and up to 10 Students are in the same room.
2.
Teacher hears everyone in the room and sees video streams from every
student (total bandwidth = 1 audios stream + n video streams).
3.
Student hears everyone in the room and sees video stream from Teacher
only (total bandwidth = 1 audio stream + 1 video stream).
4. There is no CPU intensive video encoding process on the server. Teacher receives video streams as-is plus muxed audio stream.
