mediasoup server

Hi guys,
I have a question about the mediasoup server:

I’m noticing that the source code is a hybrid of c++ and ts.
I want to know if the pure webrtc part is in this repo

or it uses another external module.
Thank you very much

WebRTC part is C++ worker in that repo. TS is just a wrapper that runs and communicates with worker.
If you really want, you can write another wrapper around the same worker.

AFAIK only some bwe mechanisms are used from libwertc here. Other webrtc things are maintained by mediasoup team.
