Could you build this?
No Migrating active WebRTC state and ICE/DTLS/SCTP sessions between browser environments and native Go processes involves low-level network protocol manipulation and stateful socket handoff.
What it would actually take: The architecture involves intercepting or serializing DTLS crypto states, SRTP keys, SCTP stream sequences, and ICE transport candidates to transfer live network state from a browser runtime into Go Pion. The difficulty is that browsers do not expose low-level cryptographic session states needed to migrate in-flight secure peer connections without re-negotiating. Requires elite WebRTC protocol engineering, browser engine internals mastery, and systems network programming.
Discussion
17 comments analyzed.
Competitors mentioned: ex_webrtc (Elixir WebRTC library), Pion (Go WebRTC framework), Google Meet API, WebRTC encoded stream API
Concerns raised: WebRTC traffic encryption complicates proxying, Single reader limitation in encoded stream APIs breaks interception, Chromium doesn't see v4l2loopback devices reliably, Google Meet doesn't expose RTCPeerConnection APIs for synthetic media, Managing multiple /dev/video* devices is cumbersome
Feature requests: Support video + PipeWire together, Container support without global state management, RTCRtpTransport for pulling video streams, Wayland DM picture-in-picture overlay integration, AI talking head integration for customer service
