[rtcweb] Call for Consensus on Use Case for Screen/Application/Desktop sharing

[Magnus Westerlund <[e-mail]>]

WG,

There where some discussion in the Interim meeting last week about a
Screen/Application/Desktop sharing support use case. My take away from
the discussion is that this use cases is likely well enough understood
to actually start a consensus call now. However, to us WG chairs it was
clear that the use case in question actually needs to be split into two
parts.

A) Where the RTCWEB enabled browser can use a local application window,
the whole desktop or a Screen as a media source that can be encoded and
transported over the peerConnection for displaying/playback at the peer.

B) Where a remote peer can provide one or more input types such as mouse
and keyboard to control the local system, not only including the
browser, but also other operating system resources. This clearly can
only happen after additional consent, most likely on a per occasion
consent.

My interpretation is that A only allows for application sharing in
conferencing contexts, like in the WEBEX session the Interim meeting was
held with where we shared slides. Where the combination of A and B is
providing for VNC/Remote desktop.

Thus the question to the WG is the following.

1) Do you support or object the inclusion of use case A, B or Both in
our Use case document?

2) Do you have additional comments for or against either of the use cases?


As WG chair
