In my ignorance, I thought SDP O/A did sort out which codec to use really well. Isn't this handled by the other endpoint, in a response, only says H.264, or puts H.264 before VP8 (if both were offered)? > This should also include ability to specify the same > codec multiple times with different parameters (for instance iLBC with > two different payloads for mode=20 and mode=30). What parameters do you have in mind? And what use case are solved? And I assume that you can only have one set of parameters for one MediaStreamTrack (to be sent). > > I should be able to control ptime and maxptime (including getting rid of > ptime all together) per m-line. Could this (from an application point of view) be expressed in terms like "low delay"? > _____________ > Roman Shpount > > > On Thu, Aug 8, 2013 at 9:54 AM, Stefan Håkansson LK > <stefan.lk.hakansson@ericsson.com > <mailto:stefan.lk.hakansson@ericsson.com>> wrote: > > Hi, > > some time back we issued a call for input on things there is a desire to > be able to control (without SDP mangling) [1].
