Hello.
I am building an interactive installation that uses input from multiple
cameras. I am trying to use the SPC900NCs because they have sufficient
feature set and reasonable price. There is also a USB sound-card that I
am trying to use at the same time.
With one camera everything works entirely ok, but as soon as I use two
there are problems. I am using camstream as a test application.
- When two cameras are in use one is forced to use low resolutions, only
160x120 and 176x144 work. If I try to choose a better image format then
camstream freezes. While this is an obvious bug it is not a huge problem
for me, since I can work with such low resolutions. This behavior is not
affected if I remove the sound-card.
- When two cameras are connected to the computer the USB sound-card
(Creative Audigy 2 NX) stops working ("Permission denied"). If I detach
the cameras during boot and attach them at some later stage then both
the cameras and the sound-card work together without any problems. This
work-a-around does not solve my problem since the system needs to run
without maintenance for several months, with reboot being the only form
of administration.
Any ideas / help?
The computer is a Pentium4-based system with SUSE 10.0 (HP Compaq DC 7600).
The cameras are connected to the computer via Targus USB hub (7 ports).
The computer has a USB mouse and a USB keyboard.
My pwc driver version is 10.0.12-rc1.
