The broadcast switcher has been one of the last pieces of production infrastructure that resisted software-defined approaches. Cameras, graphics, playout, and contribution have all moved to software and the cloud — but the vision mixer at the heart of a live gallery has largely stayed locked to proprietary hardware.
Open Live changes that. It is a cloud-native, software-defined live broadcast production platform — vision mixer, audio engine, multiviewer, and GPU rendering pipeline — released under the MIT licence and runnable on commodity GPU hardware.
What Open Live is
Open Live is a complete live production stack you can run in the cloud or on-premises, with no licence cost and no vendor lock-in:
- Vision mixer — software-defined switching at the centre of the gallery.
- GPU rendering pipeline — zero-copy CUDA-GL interop and hardware encoding via NVENC, with NVIDIA, Intel Quick Sync Video (QSV), and AMD VA-API support, so it runs across the GPU hardware you already have.
- Audio engine — up to 32 channels, EBU R128 loudness compliance, and AES67/Ravenna for professional audio-over-IP.
- Multiviewer — monitor all your sources at a glance.
- WebRTC sub-500 ms latency — low-latency contribution and monitoring, with SRT input and output and EFP for up to 16 sources for resilient contribution feeds.
- GStreamer-based and Kubernetes-native — built on proven open media plumbing and designed to scale on standard cloud infrastructure.
Three ways to use it
- Managed on Open Source Cloud — run Open Live as a managed service on Eyevinn Open Source Cloud, with nothing to install.
- Self-hosted open source — the platform is MIT-licensed, so you can self-host it on your own commodity GPU hardware at no licence cost.
- Dedicated managed instance — for a managed, dedicated deployment, contact us at sales@eyevinn.se.
