7 Installing 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.
7.1 1394 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.
7.2 STH-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
.
