For Developers

Note that AJA no longer actively supports DirectShow™ filters after the release of AJA software v15.5.2. The download links shown below are left for legacy purposes, and developers may be successful utilizing these filters, but AJA cannot assure full functionality.

Below you'll find the links where you can download AJA's DirectShow Filters. These filters were designed for DirectShow application developers, so that they could make their applications compatible with the majority of AJA's windows based hardware. These filters are meant to be used programmatically, and will not necessarily work with every DirectShow application without work being done to explicitly support them. Note: DirectShow is a trademark of Microsoft.
