Ystreamer captures and outputs two HDMI sources simultaneously over a single USB-C connection.

When connected to a computer, Ystreamer will be recognized as two independent UVC video devices, corresponding to HDMI 1 and HDMI 2.

In live streaming or conferencing applications, both video streams appear as separate camera devices named RGBlink HDMI2.0 4K+ CAPTURE1 and RGBlink HDMI2.0 4K+ CAPTURE2, allowing them to be used independently in different layouts and workflows.

Each UVC video stream supports the following formats and resolutions. Both streams can be output simultaneously.
