Make an incoming VP8 RTP stream into Erizo Publisher

Hi,

I have an IP encoder supports RTSP with H264 codec, and I want it to be a
publisher in one or more nuve rooms.

With ffmpeg or gstreamer, I can convert h264 RTSP into vp8 rtp stream
sending to licode code, but I don’t know how to make the incoming vp8 rtp
stream to be an erizo publisher.

I know there’s another project Janus gateway can take vp8 rtp into a
virtual webrtc peer, but I still need licode MCU at this moment.

Please advise how to convert a VP8 RTP stream into an Erizo publisher, or
how to make a virtual peer from Janus gateway into an Erizo publisher.

Thanks!
