OSEE GoStream M2 is a compact capture card with two HDMI inputs, featuring built-in switching and video effects. It allows users to switch between two HDMI sources or display both sources simultaneously using PIP or PBP layouts, with video output via HDMI and USB-UVC.
 
GoStream M2 is designed for users who need flexible management of two HDMI video sources for live streaming, conferences, or recording. Typical use cases include switching between a camera and a computer for presentations or combining two camera signals in podcasts and educational videos.
 
The device accepts HDMI input signals up to 4K@60p and scales the output to 1080p@60p for both HDMI monitoring and USB-UVC recording. The USB connection is plug-and-play and recognized by most streaming and conferencing software as a standard webcam.
 
In addition to simple source switching, GoStream M2 offers picture-in-picture and picture-by-picture layouts selectable via dedicated hardware buttons. Independent microphone, line-in, and headphone inputs allow direct audio integration without the need for an external mixer.
