Am I missing something here

I agree with Iñaki, I think SDP is dificult to use and overcomplicated from an API perspective, it should be an internal implementation detail, or at least WebRTC API should offer higher level functions, too.

And that is exactly the problem and limitation. We are forced by WebRTC  to use SDP but we cannot play with SDP features.

We need an API for setting  directionality of each media stream, and also an API for retrieving those attibutes from a received and processed SDP.
