WebRTC-related (signaling, media, etc) logs are in nspr.log.child-x, indeed ! I did not look in there.

I confirm that using MOZ_LOG/MOZ_LOG_FILE instead of NSPR_LOG_MODULES/NSPR_LOG_FILE is working all right in FF55. The variable WEBRTC_TRACE_FILE still has to be set to "nspr" which is kinda confusing. Perhaps updating section "Media (the GIPS stack: RTP/RTCP)" @ https://wiki.mozilla.org/Media/WebRTC/Logging could be a good idea to avoid misunderstandings about the 'WebRTC.log' file. > Randell Jesup Thank very much you for your help! _______________________________________________ dev-media mailing list dev-media@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-media
