[MMUSIC] BUNDLE/SDP : ISSUE#2: Should BUNDLE allow/disallow SSRC Repetition ?

[Suhas Nandakumar <[e-mail]>]

Hello All

  Another issue or concern that was brought up is dealing with RFC5576 SSRC
attributes across the BUNDLED m=lines.

RFC5576 does allow SSRCs to be repeated across the m=lines given that each
m=line forms a separate RTP Session.

There were two options suggested in this regard (by Jonathan)

1. Don't allow SSRC values to be repeated across the bundled m-lines
    ==> Assign category NORMAL

2. Allow SSRC values to be repeated iff the media stream satisfies more
than one m=lines, in which case, the individual sources define the behavior
  ==> We have 3 options here
   2.1 Assign Category SPECIAL and add explanatory note on possible
scenarios

   2.2 Assign Category SPECIAL and propose an update to RFC5576 to explain
behavior of a=ssrc attributes when multiple m=lines are multiplexed

   2.3 Define a new category ??


I look forward for your inputs on how do we deal with this issue.


Cheers
Suhas
