I know this question is impossible to answer exactly but what roughly
estimated CPU usage could I expect for conference with five 480p streams
transcoded at 15 fps.
One room with common core i5 quad CPU, 5 simultaneous rooms, 10 rooms?
Also I am a bit puzzled about differences between "mux" and "transcode"
video modes. "Mux" is required to place different sources on canvas
(compose completely new video stream) while "transcode" just reencodes
video source with different codec, am I right?
