[jitsi-users] VideoBridge - bandwidth on client's side


#1

Is this a new feature of jvb ? I only knew that jvb just passes along streams betwn. peers. Is there any details about "reducing the quality of the forwarded videos " please ?

Regards !

Hi Alex,

The bridge will try to estimate the available receive bandwidth of a particular receiver and adapt its sending bitrate towards this receiver. This basically works by suspending (turning off) some videos and/or reducing the quality of the forwarded videos (if needed).

I hope this helps.

Hi Peipei,

We have been working on the adaptivity features of the bridge for a while. The bridge reduces the quality of the forwarded stream, *if* the corresponding incoming stream is adaptive or if simulcast is activated. With VP8 simulcast enabled, you have 3 streams to chose from for the spatial “layer" and 3 temporal layers for each spatial “layer”.

I hope this helps.

Hi George,

These adaptive feature changes, are they incorporated in debain stable
build ? or unstable source list/master only ?

Also based on these performance is supposed to increase right - Any
benchmark if it increases the number of participants in conference?

JSZ
