Hi,

You don't need a common logic. You can define an application layer protocol (e.g. CLUE) to define/configure/negotiate these kind of things.

Šand let each RTP packet be associated with one, and only one, of those
MIDs/m-lines.


You can then have application logic saying e.g. ³If no Œloudest-speaker¹
media is received, then duplicate the Œboss¹ media on the screen
associated with the loudest speaker². It¹s much more flexible, and without
any of the constraints mentioned earlier.


I agree it brings in flexibility and it scares me a bit as well .. Each application needs to define their own logic or need a common logic across all applications ..



Regards,

Christer
