Just figured it out! Thanks for your interpretation of the docs @gvdhoorn. Really helped me think though this. For those interested: used tee's in my pipeline. gscam needs image/jpeg or video/x-raw in RGB to function properly so you have to send over udp in a separate branch.

the rtp stream in port 8004 should be detected by Janus-gateway and broadcasted over webRTC. And yes 8004 again. Yeah I really didnt have a very strong understanding of gscam. Need to take advantage of both the RGB output for image processing, but also want to broadcast a low latency video stream.

When running my pipeline with gst-launch-1.0 in terminal, I get exactly what I want to see. However, when transferring that pipeline to my gscam launchfile, no video stream is recognized on the port. Am I doing something wrong?

my launch file is just a copy of their sample with gscam_config changed:
