Hi, I have an application where two Firefox browsers make a webrtc video call between them. It works, but a problem I see happening is increasing lag in the video feed. Initially there will be a 1 second delay from the video getting from the web cam to the receiver. Then as the call continues the delay grows to 2 seconds, then 3, 4... and so on, continually getting worse. My PowerMedia XMS is 3.1.12 from the iso, running in Hyper V. Things I have tried to rectify the problem: Reduce the video resolution Increase the priority of faster audio/video codecs (opus and VP9, although it seems to choose VP8) Set media_path_optimize="yes" in the restful api calls (on join it breaks, on call does nothing) Set Video Coder Sharing: Static in the web Console Codec settings Reducing the maximum transmission units of the eth connector on XMS: "ifconfig eth0 mtu 1300" I have wondered if it is a buffering issue in the browser, or timing problem between the server and client. In the "messages" log file I see lots of lines like: Oct 27 13:59:48 xms systemd: Time has been changed Oct 27 13:59:53 xms systemd: Time has been changed Oct 27 13:59:58 xms systemd: Time has been changed Oct 27 14:00:08 xms systemd: Time has been changed I have tried disabling ntp ("service ntpd stop"), which gets rid of the messages but doesn't fix the problem. Also trying to set the NTP service in the Web Console doesn't save, and reverts to disabled. Anyone have any suggestions to what the problem is? Thanks, Brendan
