[sr-dev] RTPEngine - Support for Unified Plan SDP Format

[M S]

Hi,

Since Chrome M72, the default format of SDP generated by Chrome's WebRTC
stack has been changed to "unified-plan" instead of  Google's old "plan-b"
format, which has no been deprecated and planned to be removed sometime in
mid 2020. Here are more details about it.

This poses a big problem for non-web WebRTC clients, servers and proxies
(such as RTPEngine) which will stop working as soon as Google Chrome
removes support for legacy "plan-b" SDP format.

In kmaialio's RTPEngine module, so far I have seen no support for this new
"unified-plan" SDP format.

Are there any support planed for future?

Meanwhile, if there any way to add support for it in Kamailio via SDP
manipulation e.g. SDPOPS module etc.

Thank you.
