Very easy to use with VLC (free software). Just click "Media" menu and choose "CY3014 USB" for Video and Audio device.
We can view the captured video in real time and in any size, take snapshot, record, and stream (with VLC). We can use the software that comes with the box, or some others, too.
This box allows us to use a laptop (or a desktop) with USB3 as a display for VGA, DVI, HDMI, S-video, component. So, we can debug a machine without having another display/monitor. We can use Laptop or desktop screen as a video monitor, too. Highly useful!
