[Freeswitch-users] Fwd: Video conference with transcode mode is not working more than for 5-6 users

[Александр Дружилов]

My use case is to make video conference where anybody can share his video
from camera or share screen. Video from camera and screen could have
different resolutions and frame rates so I would prefer transcode because
mux forces me to use a fixed frame rate and canvas size.
