7 Installing the 1394 Host Card and Capture
Software
The STH-MD1/-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 7-1). The STH-MD1/-C comes with interface software for either
MS Windows 98/2000/XP 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.
7.1.1 MS Windows Hardware Installation
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 98/2000 CD to install some files.
7.1.2 Linux Hardware and Driver Installation
Linux kernels 2.4.x are required for operation. Please see the Videre
Design website (
www.videredesign.com/support_svslnx.htm ) for current
information.
Sometimes the 1394 system will get hung and you have to unhang it by
removing all the modules, and re-installing them. Also, the Linux IEEE
1394 drivers sometimes do not configure the root node of the bus properly.
Check the listing of /proc/ohci1394 to see if the word “root” appears near
the top of the listing. If not, you can sometimes get around this problem by
using:
modprobe ohci1394 attempt_root=1
when installing the OHCI 1394 module.
7.2 STH-MD1 Software
The STH-MD1/-C comes with interface software and several sample
applications, including the capture application described in this manual.
To install the software under MS Windows, execute the file
svscap21X.exe
. The installation process will add the relevant
interface and application software.
To install the software under Linux, untar the file svscap21X.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.
The directory structure for the software is:
bin/
smallvcap(.exe)
smallv(.exe)
smallvcal(.exe)
stcap(.exe)
stdisp(.exe)
svsgrab.dll/lib
