Re: [XCON] Consensus Call: CCMP Muting interaction with BFCP

["Oscar Novo" <oscar.novo at ericsson.com>]

Hello Jonathan,

Note that the data model defines multiple elements of doing the same
things. It's up to the conferencing system to correlate those elements
in the proper way.

And, Good catch! The VideoIn and VideoOut values in the example are an
error indeed.
I'll fix it in a next version of the data model.

Thanks Jonathan!

Oscar

I agree that BFCP and CCMP should operate independently in this respect.

A related question, though, is that CCMP (via the common data model)
seems to have multiple ways of muting a user.  Do the
endpoint/media/status=recvonly and
endpoint/media/controls/to-mixer/mute=true states operate independently?
Are the authorization requirements for the two expected to be different?

(I'm in general perplexed about the to-mixer and from-mixer controls in
the common data model -- is the presence of "VideoIn" and "VideoOut"
mixers inside a media/type=audio block in the example in
common-data-model-13 an error?  If not, what does it mean?)
