webrtcsink: doc out of date (not able to run the demo pipeline anymore)

Hello,

since webrtcsink has migrated to gitlab, file structure has changed, and the Usage procedure seems out of date:

• Trying to run the signalling server using this command line does not work anymore:

WEBRTCSINK_SIGNALLING_SERVER_LOG=debug cargo run --bin server

• Seems like I can run a signalling server following these steps:
  • cd into gst-plugins-rs/net/webrtc/signalling directory and run cargo build
  • go to the top repository directory and run the following command:

WEBRTCSINK_SIGNALLING_SERVER_LOG=debug cargo run --bin gst-webrtc-signalling-server

• However, consequently running the http server and the demo gst-launch pipeline doesn't succeed on my Ubuntu 20 distro (black video screen on the web page)

Am I doing something wrong?

Thanks for your help,

Albert
