AVerMedia DarkCrystal HD Capture SDK Duo


The Kernel Labs Linux Driver for the AVerMedia DarkCrystal HD Capture SDK Duo (Model C129) allows for the deployment of the raw HD video capture in desktop, server, or datacenters.

The C129 is well suited for environments where video is captured, processed (scaling, overlay injection), and rendered. Ideal use cases include Digital Signage, Media Monitoring and Health Care, as the C129 delivers pixel perfect audio and video with extremely low latency. The C129 can capture two HDMI streams simultaneously.
