The VisionLC-HD2 Dual-Channel LiveStream Capture Card from Datapath provides dual-channel HDMI video and audio capture for small form factor appliances being used in medical environments, simulation systems, lecture capture, real-time streaming, and videoconferencing. The card allows captured video to be processed and delivered in real time to a processor or graphics card.

The VisionLC-HD2 capture card supports onboard color space conversion and scaling, providing the ability to efficiently transfer the video signal in a suitable format for rendering or encoding applications. It natively supports 32-, 24-, 16- and 12-bit YUV and RGB formats. Built upon the Microsoft AV Stream framework, the card's inputs can be accessed and enumerated by any DirectShow or Media Foundation supported application. A Video for Linux (V4L) driver package is available for download.
