Simulcast support for webrtcbin

As I can see from source code of webrtcbin, it does not support simulcast. Is it possible to add? If yes, can somebody give me roadmap ?

For now I plan to do the following:

  • Build pipeline where webrtcbin will have 2 sink pads to handle streams with different bitrate and size:
source0 --> tee --> encoder0 --> webrtcbin0
                \-> encoder1 --> webrtcbin0
  • Inside webrtcbin add funnel element which will "mux" packets from sink pads into one stream
  • Modify Offer to add information about simulcast
