[rtcweb] Basic scenario 'impossible?' to achieve with the actual API

[José Luis Millán <[e-mail]>]

Hi,

Please, let me know how this normal use case could be solved with the
current API.

Alice and Bob have accessed to a Web page offering a basic WebRTC
application   that they use to speak and see each other. They are in the
middle of a media session right now.

Alice presses the "Video" button in her web application. A SDP offer with
video description is sent to Bob:

Bob doesn't want to see her, so his web application rejects the media by
using any valid method for that:
-- a=inactive
-- m=video 0

Alice web application received a SDP answer which was consumed successfully
by the RTCPeerConnection. Alice thinks she is sharing her video, but she is
not.

The application "Video" button is disabled since the video is already being
shared (theoretically)

The application "self-Video" HTML5 video element displays Alice's face. She
thinks that Bob is seeing her face too, but he did indeed rejected so.

I hope this common scenario can be achieved somehow with the current API. I
can't find how to do it though.

Thanks in advance
