Participate without calling getUserMedia at the beginning

[peili]

I would suggest a feature to enable attending meetings without being forced to allow audio/video access when entering room. This is for some users a privacy issue.

If the participant decides to share audio/video you could call GetUserMedia at a later time.

Yes, we should probably start by making sire that a participation is not cancelled when access to user media is refused. We'd need this to be properly signalled to all participants though. Incluing the one who is refusing media access.

I tried to just call doJoin() and skip getUserMediaWithConstraints() to participate without sharing my audio/video. (see app.js init() function)

However receiving audio works, but video does not. Any idea?

See also #6 and the haircheck stuff...

So setting m-line to be recvonly causes the problem that video is not displayed?
Do you think it might work instead of calling getUserMedia creating a dummy localMediaStream?

I'd suggest to use this also in case when the participant doesn't have a webcam. For now if a user do not have a webcam or do not allow it, it looks for him like nobody is present at the conference, and textchat doesn't work.

I just want to echo what @zalmoxisus said. There are cases where someone wants to join as an audio-only guest without a video camera, which is currently blocked.

Sometimes users just want sharing screen and they don't have webcam. It's really a good idea than a participant can join a room without webcam.

Implemented.
