It does not, however, relieve you from SDP munging on the transport side.  But as I've pointed out, that's limited to about 10 lines of SDP, so at least it's much less SDP munging.  Later, once could consider more simple additions that reduce the need for SDP munging further.


You base your proposal on the fact that SDP is here forever and must
be used in WebRTC, and then propose some new API methods along with
*lot* of SDP JS parsing/mangling/hackery to mitigate the API
limitations.

While it could be the best we have for now, IMHO it is still a hack or
workaround to just circumvent the real problem and the real
limitation.

Things can be done much better if we remove SDP from the equation.


Best regards.
