What I can I say, yes. Please come back with specific questions if you need help
doing so, this is too broad of a quesiton. GStreamer can be used to bridge a
webcam from your PC to a WebRTC channel so you WebRTC enabled AWS node can
injest. This is not a ready made solution though, GStreamer is a framework that
will let you build a customized solution for your specific needs.
