Did you mean to say that BUNDLE should NOT forbid this?

Based on your GitHub discussion, my understanding is that you want to allow to include RTP-specific parameters (‘rtcp-mux’, ‘rtcp’, ‘rtcp-mux-only’ attributes etc) in the data m= section.

Yes/


To repeat what I said on GitHub:

This has been discussed in the past, and the outcome has been to now allow RTP-specific parameters in non-RTP m= sections.

Do you mean "not" rather than now?

A solution would be to simply change the bundle tag when the RTP m= sections are added.

…OR, we change the mux category for the RTP-specific parameters. But, that of course means they have to be added to every RTP m= section.

Christer
