Does WebRtc bundle policy `max-bundle` support?

[MCCM Yu]

Hi,

Does RtpEngine support WebRTC `a=group:BUNDLE` as shown RFC8843?

In common case, RtpEngine uses audio and video ports respectively.

Can we use RTCPeerConnection bundle policy, `max-bundle` toward RtpEngine?

Currently our BUNDLE support is limited to breaking up bundled SDPs. IOW
rtpengine can receive them and work with them fine, but will never
produce BUNDLE SDPs itself. So if your client expects to receive bundled
SDPs and rejects non-bundled ones, then things might not work.

Cheers

If so, Is there any plan to support  `a=group:BUNDLE` for offer SDP from rtpengine?

Because, It is possible to be deprecated soon that bundle policy, `max-compat` to handle none BUNDLE SDP from rtpengine.

Eventually, yes, but I can't give a timeline. Hopefully before things
start breaking without it 🙃
