7Installing the 1394 Host Card and Capture Software

The STH-DCAM connects to a host computer via a digital 1394 interface. The host PC must have a 1394 port, and software to interface to the video stream from the camera. This interface software presents the video stream from the 1394 hardware as a set of stereo frames to the user program (see Figure 7-1). The STH-DCAM comes with interface software for either MS Windows 98/2000 or Linux.

7.11394 Hardware and Drivers

Before installing the software interface, the PC must be equipped with a 1394 port. If there is one already present, on the motherboard, then you can skip this section. Otherwise you have to install a PCI or PCMCIA card. The card must be OHCI compliant, which all current cards are.

Please see the Videre Design website (www.videredesign.com/support.htm) for the latest information about installing hardware and software drivers.

After installing the card, install the STH-DCAM driver software.

7.2STH-DCAM Software

The STH-DCAM comes with interface software and several sample applications, including the capture application described in this manual.

7.2.1 MS Windows Installation

To install the software under MS Windows, execute the file svscap22X.exe. The installation process will add the relevant interface and application software.

The directory structure for the software is:

bin\

smallvcap.exe

stcap.exe svsgrab.dll, .lib dcamcap.dll, .lib

src\

svs.h

svsclass.h

samples\ *.cpp

*.dsp, samples.dsw

There are two applications. smallvcap.exe is a GUI-based application that allows the user to exercise the capture functions of the STH-DCAM. It is described in earlier sections of this document.

stcap.exe is a simple application that connects to the stereo head and displays stereo images. It can serve as a template for user programs that integrate stereo capture from the STH-DCAM.

libcap.dll is the capture library for Linux. These libraries must be set to the correct ones for the STH-DCAM. Copy the following files in the bin\ directory:

svsdcam.dll -> svsgrab.dll svsdcam.lib -> svsgrab.lib

You can check that the correct interface library is installed, by looking at the information text when the capture application is started. It should say “Dual DCAM digital stereo interface”. If not, the wrong interface library is installed in svsgrab.dll.
