Quality problems with VideoRoom (multistream) plugin

General

Hey guys,

I’m running a local Janus WebRTC server inside Ubuntu WSL2, and I’ve noticed some major performance and metric differences compared to the official Janus demo server. On my local instance, the plicount is around 60, nackcount is 0, and totalPacketSendDelay is very high (~30k), while on the remote demo server, plicount is 0, nackcount is around 6, and totalPacketSendDelay is very low (~0.8). Also, on the local Janus, the framerate fluctuates a lot, whereas on the remote one it stays stable at 30 fps.

Does anyone know what might be causing these discrepancies between a Janus instance running in WSL2 and the official demo server?

Also I see this Error log from janus repeatedly : [ERR] [rtcp.c:janus_rtcp_transport_wide_cc_feedback:1885] Delta value (41249) too large, reporting it as 32767

Your Janus instance may simply be struggling to keep up, or be misconfigured. Profiling with tools like gprof or something similar may help you identify where the code is too busy. Also try playing with settings like event_loops (core) or helper threads (VideoRoom).
