I guess I would need something like Kurento then inorder to do what I am trying to do?

My question is, can rtpproxy or rtpengine perform this transcoding? If so, and if rtpengine is the way to go, should I use Ubuntu for the rtpengine since it is the only one that seems to have a working installation? Work on transcoding support for rtpengine is currently underway. However, the initial focus will be on audio codecs only. Video support might be added in the future. Cheers

Hi Steve, In the past I've used WebRTC2SIP gateway project from doubango : https://www.doubango.org/webrtc2sip/ I was able to do transcoding for video calls as well. As far as I recall it was CPU intensive and may require some WebRTC(HTTP/HTTPS) loadbalancing to be able to handle an satisfactory amount of calls. In my scenario I had to transcode VP8/VP9<==>H264 streams. I hope we get better( & efficient) video-transcoding projects soon.
