Want to use only one byte header extensions for the audio for routing audio on low bandwidth link. Anyhow many of the RTP header extensions will be different between the audio and video

Yes, I understand that, but why would you not want to mix? I assume merely because your implementation can't handle it, right? Is there some other reason?

[Roni Even] It is not a question about handing mixing if you bundle but if there is a use case where you do not want to mix for one of the m-lines. This is the discussion since even if you use normal you can still do identical (for example by having the allow mixing at the session level) but not the opposite.
