I have some troubles with connecting external video source. In stream in OM room, audio and video are jerking. But if I streaming video whitout audio stream, it playing normally. And if I show mp4 container without video stream it is jerking again.
Changing ffmpeg keys didn't help. Running ffmpeg whithout encoding (-acodec copy) didn't help. No different between file on server or internet stream.
VMs config: 4GB memory, 4 processors, everything busy max on 20%. IP traffic not busy.
Ping time ~ 0.600 ms.
It's demo file of sound and video jerking attached
Have you some idea that's wrong?
