Hi,

Good work!

This should be available at least be per-media, ideally even
per-candidate (to support trickling). Having it per-media without the m=
line means that one can just put the blob from libnice inside you SDP
without having to mangle it. Possibly also add some API to get the
recommended default candidate (ie, the lowest priority).

Also, not everyone uses the RTP/AVP profile, for example WebRTC mandates
RTP/AVPF, I would just not provide an m= line at all.

Also, please check https://tools.ietf.org/html/draft-ietf-rtcweb-jsep-02
as I believe this will become major user (it's the candidate API for
WebRTC).
