on YouTube ↗09m

" summary

A live-coding video mixer exists and is demoed working: Overscan live-coding environment composes camera, screen, drawings and text into a Twitch broadcast in real time. The implementation is specific: Racket + GStreamer + GObject Introspection glues a Scheme REPL to media pipelines. The demo shows picture-in-picture, scripted fades, on-screen drawing and a running build that streams from the presenter's machine; software is alpha and requires Reiko package install and GitHub sources.
