Particularly, I have a pipeline that receives multiple udp streams, decodes them, combine decoded frames in one big mosaic frame and encodes that mosaic. Next I want to be able to send that mosaic over WebRTC to possible clients. Finally, my purpose is to be able to watch this mosaic in a web browser.

I would recommend Janus (https://janus.conf.meetecho.com/) it has an
example of taking RTP (h264/vp8 and Opus) to WebRTC out of the box

https://github.com/meetecho/janus-gateway/blob/7c9bddfe2ef1d6fca6572590ce03f0e207fdec4c/plugins/streams/test_gstreamer.sh

It also is all C/glib so very easy to work with IMO
