Hi All, I'm having some problems with my DC10+ and hope somebody could give me a hint where I can be looking, etc.
I'm using the DC10+ card, line input from a wireless camera. Unfortunately the wireless camera gets interference from other house devices (power supplies, microwave oven, etc), so sometimes the signal gets corrupted, and interference appears on its output. This seems to de-stabilise anything capturing from the driver, and requires applications to be killed and restarted. I'm trying to decide/find if this should be detected/handled in the software or kernel driver, so bear with me if this is nothing to do with the zoran kernel driver, please just tell me so! I'm calling the module: /sbin/insmod zr36067.ko card=2 v4l_buffsize=512 v4l_nbufs=32 debug=0 cat /proc/interrupts shows: 11: 430539787 XT-PIC DC10plus[0] (on its own IRQ) At init with debug: Zoran MJPEG board driver version 0.9.5 ACPI: PCI Interrupt 0000:01:08.0[A] -> Link [LNKA] -> GSI 11 (level, low) -> IRQ 11 MJPEG[0]: Zoran ZR36057 (rev 1) irq: 11, memory: 0xff8fe000.
