I am really excited for this PR to land. Being able to use WebRTC for Broadcast and Playback is going to be huge.

Instead of doing fixed interval keyframe we can use receiver feedback (Massive reduction in bandwidth)

Instead of server side generated transcodes we can use Simulcast. Will be better quality AND massively reduced server load.

If anyone wants to use with Pion check out https://github.com/Glimesh/broadcast-box
