Question

How do I send my local video stream to multiple remote peers? Do I need to instantiate one PeerConnection per remote peer? Or can the same PeerConnection be used for all remote peers at the same time?

Answer 1

According to user dom on #webrtc on irc.w3.org, each PeerConnection is associated with a single remote peer. The developer is responsible for sharing the same stream instance with multiple PeerConnections:

<Cow_woC> dom: Or am I responsible for keeping the reference around and passing it to multiple PeerConnections?
