Hi, ... >>>>> If I remember correctly, there was a suggestion to keep the existing port zero + bundle-only procedure in JSEP, but define a NEW policy for it. Then, once the new policy gets implemented, it can be used. >>>> >>>> Yes. I had suggested that, and still think that could be a path forward. But we should first see what the aforementioned data says to understand the extent of the need for such a policy. >>> >>> We have been talking mostly about 'max-bundle'. But as far as I understand (and you also mentioned it earlier in the thread) we have the same issue with 'balanced', if the offer contains more than one m- line for the same media type. Or? >> >> You are correct, but the scope of this issue is believed to be far smaller, given the slow adoption of unified plan (which is required for multiple m= lines of the same type). IOW, we may choose a different solution here than in the max-bundle case. > > Are you saying that browsers currently don't support multiple m= lines of the same type? And, just to clarify the above: browsers are currently using "Plan B", where all tracks of a given media type is placed inside one m= line, and the tracks are then separated using SSRC?
