Thanks Nils!

Unless someone objects, the plan is to merge the PR and submit a new version of the draft next week. Then we can hopefully do the pub req.

Regards,

Christer

I’m in favor of your proposed change, because the use case is small, there is a work around, and the code for handling this (hopefully rare) use case is really complex.

Subject: [MMUSIC] BUNDLE: Disallowing moving an m- section between BUNDLE groups within a single SDP offer

(CC:ing RTCWEB, but please reply on the MMUSIC list)

Hi,

Would anyone object to not allowing moving m- sections between BUNDLE groups within a single O/A transaction? The documentation of that is a little more complicated than I thought, and there is a risk the text becomes more confusing than it already is.

Note, that one could still send an offer where an m- section is moved out of a BUNDLE group, and then send another offer where the m- line is added to another BUNDLE group (following the normal procedures for adding an m- section to a BUNDLE group). But, one would not be allowed to remove and add within the same offer.

Regards,

Christer
