WHY??? What can i do?
I want have image 640x480 or higher

Hi,

Funny this... I just built a system using the FlyVideo EZ(Conexant Fusion 878) card. I also initially had issues setting it up with the card.
I now have it working at 640x480, for the past 2 days now.

Firstly I am running CentOS 4.3 64bit. The first problems I had were that the zmc kept bombing out on me after a few seconds and would kill all networking. wierd, so I upgraded the BIOS on the motherboard(ASUS A8-VM), which resolved ACPI issues and a few other minor bugs. After that the system was more stable. I then downloaded the latest stable kernel from kernel.org, 2.6.16.18 and recompiled to include video 4 Linux and the BTTV drivers. The card loaded ok after that, and had to add to module load options card=30. Video was spot on after that.
The other thing I changed was Shared memory allocation; Since this system is only taking 1 camera, I set up the shared memory as follows;
this sets the SHM to 256MB;
shmall=268435456
shmmax=268435456

you edit the sysctl file or echo the values into the running kernel;
echo 268435456 > /proc/sys/kernel/shmall
echo 268435456 > /proc/sys/kernel/shmmax

what version of ZM are you running?

what are your buffers set to in ZM?

can you view the video ok through awktv at 640x480?

At the end of the day, mine was more of a combination of motherboard bios and kernel and Shared memory setting

-M

Thx...

With this options all worked:

echo 268435456 > /proc/sys/kernel/shmall
echo 268435456 > /proc/sys/kernel/shmmax
