Pion’s Handoff tool lets developers create WebRTC sessions in a browser and then hand them off to a controllable backend process.
By mocking the browser’s WebRTC API, Handoff forwards signaling to a server that can record, replace, or forward media streams—e.g., swapping a webcam feed with FFmpeg-generated video.
Examples demonstrate media capture, storage, and RTP injection, all while keeping the browser view live. The open‑source project ships with a Greasemonkey script and a Discord community.
Pion’s MIT‑licensed library enables enterprises to offload real‑time media processing, improving scalability and offering new use cases like secure media archiving and custom stream manipulation.
