Re: How can I install WebRTCSink on Ubuntu 22.04

Thanks Mathieu.

I had been working through the documentation, but the links to the signalling server and the API, from this section of the documentation you linked to, at https://gstreamer.freedesktop.org/documentation/rswebrtc/index.html are returning a 404 error.

rswebrtc

(from gst-plugin-webrtc)
All-batteries included GStreamer WebRTC producer and consumer, that try their best to do The Right Thing™.

It also provides a flexible and all-purposes WebRTC signalling server (gst-webrtc-signalling-server <https://gstreamer.freedesktop.org/documentation/signalling/src/bin/server.rs>) and a Javascript API (gstwebrtc-api <https://gstreamer.freedesktop.org/documentation/gstwebrtc-api>) to produce and consume compatible WebRTC streams from a web browser.

also, as referenced later in the documentation.

I suspect I will need to build or install this signalling server in order to proceed.

Many thanks again for your help, which is most appreciated :-)
