4 Installing the 1394 Host Card and Capture
Software
The STH-DCSG/-C 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 4-1). The STH-DCSG/-C comes with interface
software for either MS Windows 98SE/ME/2000/XP or Linux.
4.1 1394 Hardware and Drivers
Before installing the software interface, the PC must be equipped with a
1394 port. If there is one already present, a built-in port, 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.
4.1.1 MS Windows Hardware Installation
For the most up-to-date information about installation, please see the Videre
Design website (
www.videredesign.com/support_svsmsw.htm
).
MS Windows 98SE, ME, 2000, or XP is required.
For a PCI card, insert the card into a free PCI slot with the computer power
off, and start the computer. With a PCMCIA card, insert it into the
PCMCIA slot. In either case, the New Hardware wizard will walk you
through installation steps for the low-level drivers. You may need your MS
Windows OS CD to install some files.
The STH-DCSG must be powered from the IEEE 1394 bus. Desktop PCs
supply power to the bus; laptops do not. See Section 5 for information
about cabling and power for the IEEE 1394 bus.
4.1.2 Linux Hardware and Driver Installation
Linux kernels 2.4 or 2.6 kernels are required for operation. Please see the
Videre Design website (
www.videredesign.com/support_svslnx.htm
) for
current information. GCC 3.x is recommended as the compiler; there is a
separate SVS distribution for GCC 2.95.x, but it is not as reliable.
4.2 STH-DCSG
Software
The STH-DCSG/-C comes with the SVS stereo software, and several
sample applications, including the GUI application described in this
manual.
For the most up-to-date information about installation, please see the Videre
Design website (
www.videredesign.com/support_svsmsw.htm
).
To install the software under MS Windows, execute the file
svsXXX.exe
.
If you have installed a previous version of SVS, the installation wizard will
ask you if you want to un-install the old version. It is best to uninstall the
old version, then start the installation file again and install the new one.
The installation process will add the relevant interface and application
software.
To install the software under Linux, untar the file
svsXXX.tgz
in a new
directory, which will become the top-level directory of the software. You
should also set the environment variable SVSDIR to this directory, and add
bin/
to your LD_LIBRARY_PATH variable.
libsvscap.so
and
svsgrab.lib/dll
are the capture libraries for
Linux and MS Windows, respectively. These libraries must be set to the
correct ones for the STH-DCSG.
