4.2 Accessing the Camera Driver
Section 4.1
describes the standard layer in terms of the PHYTEC
FireWire-CAM series.
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 access
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 series. 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.
