The Osee GoStream Duet is a compact multi-camera live production and streaming video mixer designed for hybrid broadcast, live events and content creation. It supports a wide range of input sources, including SDI, HDMI, USB-C, NDI HX and SD/SSD playback, giving you the flexibility to build complex live setups without additional external converters.
With built-in streaming capability, advanced switching tools and multiple control options, it is designed to handle both simple and multi-layered productions from a single unit.
The GoStream Duet acts as a central live production hub. Cameras and sources connect via SDI, HDMI or USB-C, while network-based sources can be added via NDI HX. Media files can also be played back from SD or SSD storage.
You can switch between inputs live using the built-in interface, companion software, or external control systems. The mixer then outputs a finished programme feed for direct streaming or integration into software like OBS or vMix.
This unit combines hardware switching, streaming and audio processing in one system, reducing the need for separate encoders, mixers and control surfaces. The expanded input flexibility makes it suitable for evolving setups where different camera types and workflows are used.
Firmware V2.2.0 enhances usability further with improved audio tools such as noise gate, compressor and equaliser, plus automated switching based on audio levels for hands-free production control.

Yes, it works with software such as OBS and vMix.
Can it stream to multiple platforms at once?
Yes, up to three platforms simultaneously.
Does it support NDI sources?
Yes, it supports NDI HX sources (firmware update required for license features).
Can it be controlled remotely?
Yes, via built-in GUI, Mac/Windows software, or Bitfocus Companion.
