NO...it is possible that some of the device may prefer to loop back only one
of the stream (audio) and not the other streams (like Video).

Thanks

|
|Howdy,
|during IESG review of the media-loopback draft, a discussion arose
regarding the language around
|indicating media-loopback support per media description (i.e., per m-line),
in sections 3.1 and 3.2.
|
|My interpretation/understanding was we were requiring ALL m-lines to
indicate media-loopback; in other
|words it's an all-or-nothing in both the offer+answer, and either every
media stream is looped back,
|or none are.  However the text currently doesn't make this clear, and it
could be argued either way,
|with pro's/con's either way too; so I'd like the WG's consensus on whether
it should in fact be an
|all-or-none approach, or not.
|
|Please respond to this email by **Tuesday, December 4th** with a "YES" if
the draft should mandate ALL
|media be looped-back, or "NO" if it should allow a hybrid approach of some
streams being looped while
|others are not.
|
|For reference, the draft is here:
|http://tools.ietf.org/html/draft-ietf-mmusic-media-loopback-24
