[webrtc/multiparty-sendrecv] Is remove_peer_from_pipeline work?
Hi.
I'm developing streaming service using webrtcbin. It has one video source and many connections of webrtc clients. So, I used 'tee' and 'webrtcbin' like as example of webrtc/multiparty-sendrecv.
I runned mp-webrtc-sendrecv like as below.
./mp-webrtc-sendrecv --room-id=1

I saw remove_peer_from_pipeline was called. However, it still had sockets(2 LISTEN and 2 CLOSE_WAIT).

Do you have any advice on how could I do that?
