VideoWrapper_PtGrey Details

The VideoWrapper_PtGrey API adapter allows VideoWrapper to support cameras driven by the PGR FlyCapture SDK v. 1.5 from Point Grey Research.

The FlyCapture SDK is required to build the VideoWrapper_PtGrey source and the FlyCapture run-times are required by the VideoWrapper_PtGrey binaries. Please visit http://www.ptgrey.com/ to download.
