[jitsi-dev] Audio level display in Jitsi-meet


#1

Hi,

How Jitsi-meet web application learns the audio level for each participant?
As far as I know audio level is coming from RTP packets, but how Jitsi-meet
web app knows it?

Thanks,

HI,

For remote audio levels there are coming from rtp stats from webrtc:

Thanks Damencho,

So WebRTC Javascript API provides the webrtc statistics.
