Multicast WebRTC

[GStreamer-devel mailing list]

Hello,

I have a gstreamer program that sends video using WebRTC to a browser.
I was wondering if it is possible to use multicast to send the same signal
to several browsers concurrently, and would appreciate some hints on how to
do it.

The pipeline bellow is the one I am using:
videotestsrc pattern=ball ! video/x-raw,width=320,height=240 ! videoconvert
! queue ! vp8enc deadline=1 ! rtpvp8pay !
 queue ! application/x-rtp,media=video,encoding-name=VP8,payload=97

Thanks in advance!

No, Multicast (the UDP multicast meaning) is not possible in WebRTC as
WebRTC is not designed for that.

WebRTC is a peer-to-peer specification.

There are however e.g. SFU solutions (intermediaries) that allow sending
a streams to multiple peers.

Thanks for the hint, I will check it out.
I've also seen that it is possible to use a tee to re utilize the same bin
for different connections.
