Show HN: Live streaming for CUA models using WebRTC (OSS, Apache 2.0)

2•juecd•6h ago
Hey HN,

We’ve been building on top of our browser-unikernel repo [0] and wanted to replace the noVNC remote GUI with something much faster. NoVNC is okay but it’s super laggy with any JS-heavy website (basically anything besides Hacker News…). We added remote GUI support using WebRTC, which supports:

- low latency read/write live view into the sandboxed browser (scrolling, clicking, typing feel way more responsive)

- can launch directly as a Docker container or on Unikraft unikernels

- process real-time streams with a fast boot up time (<20ms) if you’re using unikernels

WebRTC is powerful (supports all types of media and data transmission) but not trivial to implement. We adapted the Neko [1] library to play nicely with our base Chromium image. We also tailored the frontend to our use case.

Would love any thoughts/feedback from folks who’ve worked on streaming projects before.

* Note: we've started working on adding video replays, so there's some source code for that already in our repo too.

Nice work! I saw the same quality improvement switching from from VNC -> WebRTC.

Thanks for publicizing you used neko. I am sure it means a lot to the authors :)

Thank you! Just saw your GH, will check out your WebRTC work more deeply :)
