I used webrtcendpoint、hubport、kmscompositemixer plugins, now I found the delay have about 280ms ~ 370ms (1~12 participant in room). The video resolution is 1920x1080, encode format is VP8. I refer GStreamer official document trace latency: export GST_TRACERS=latency export GST_DEBUG="GST_TRACER:7" but Kurento is crash. Now I stat some elapse: decoder(elapse 3ms) / composite(elapse 12ms) / encoder(elapse 16ms), srtp enc and dec elapse 0 ms, I found the elapse is so small.
So, I want to know how can I trace where the delay?
