The Harrier USB SDK has been developed for use with USB Video Class (UVC) compatible Harrier products. It provides classes, a library of functions, classes and example applications (source code available on request) that acquires UVC video/images from UVC compatible Harrier products, e.g. the Harrier SDI Adapter and the Harrier USB/HDMI Camera Interface Board. Harrier UVC compatible devices stream video from their input ports (e.g. 3GSDI/HD-VLC) to their USB 3 output port. The Harrier USB SDK example applications acquire video/images (over USB) from Harrier UVC compatible products, and can also be used to change the camera video output mode and other camera UVC properties via the USB connection.

The Harrier USB SDK provides the following functionality:

  • Live video acquisition from the Harrier UVC compatible products up to 1080p60.
  • Real-time display of the acquired video.
  • Video encoding to H.264 and streaming to disk (MP4).
  • Text and image overlay.
  • Capture and storage of still images (JPEG and TIFF).
  • Selection of camera video output mode and other camera UVC properties over USB/UVC.

With Harrier UVC compatible devices, the application software can use several standard APIs, including Microsoft Media Foundation or DirectShow. The Harrier USB SDK is based on Microsoft Media Foundation. It is a set of modules, classes and example source code designed to enable quick and easy development of UVC based applications that capture video/images from Harrier UVC compatible products. Microsoft Media Foundation enables the development of applications for using digital media on Windows 7 and later versions of the Windows OS. The SDK provides objects that acquire, encode and display video. The classes provided in the SDK can be used as-is in an application, or as an example to develop a custom application based on Media Foundation.

The SDK example of video encoding uses a Media Foundation Transform (MFT) which must be installed on the host machine. The default H.264 MFT available under Windows runs entirely in software and does not use any hardware acceleration. Hardware-accelerated MFTs are available from Intel or NVIDIA; both require the appropriate acceleration hardware to be available (e.g. an Intel CPU with QuickSync support, or an NVIDIA GPU with built-in NVENC support).

Example Applications

The example applications included with the Harrier USB SDK implement the Active Silicon and Media foundation functions/classes. The Harrier USB SDK contains a .NET wrapper that enables the SDK API to be called from .NET based languages (C#, Visual Basic, C++/CLI). This enables developers to write code in C#, VB or C++/CLI to implement image acquisition, display and video recording functionality using the Harrier USB SDK.
