4.2 Accessing the Camera Driver
Section 4.1 describes the standard layer in terms of the PHYTEC
FireWire-CAM-001/002.
A progammer sees these cameras at the layer of a WDM Stream Class
driver. The communication between this type of driver and an
application software is defined by the standard called DirectX /
DirectShow.
There are three typical ways of accessing a WDM Stream Class
driver.
•
Programmers who have experience using DirectX can acces these
drives directly using DirectX.
Programmers who are not experienced with DirectX can access the
driver with the help of the PHYTEC FireWire-SDKs. The SDK
allows easy access from standard Windows programming
environments. In terms of software the camera behaves similarly to
a standard camera-framegrabber unit.
The FireWire-SDK with the DirectX-Wrapper is included with the
PHYTEC FireWire-CAM-001/002. It can be found on the
CD SO-221 along with the detailed descriptions of the functions.
•
If you would rather avoid programming entirely, you can use the
Filter Graph Editor to parameter WDM Steam Class drivers.
