Send a fake stream when a new connection is created

[Donorhan]

What is the current behavior?

Several actions are triggered when an user goes to talk to another user:

• PeerJS notifies the user B that the user A wants to talk to him
• The user B accepts or not the connection
• If the connection is established, getUserMedia is triggered and returns a stream to send to the other user A
• The user A is notified of a new connection and receives the stream from the user B

The problem is that getUserMedia can be long: from 1 to x seconds during this time the calling user does not receive any news from the remote user.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

What is the expected behavior?

What is the motivation / use case for changing the behavior?

By creating a fake stream (without sound and a black pixel) we can very quickly respond to the remote user and thus have a more pleasant experience. Then you just have to update the "tracks" of the fake stream with the real tracks.
