On the upstream 'ov511' page: http://alpha.dyndns.org/ov511/install.html ...it says: <snip> Using Compression Support: This information is only valid for the stable driver series (1.xx). With 2.xx drivers, compression is already built into ov511.o. For more information, please see the README that comes with the driver. Compression support will give you better frame rates with OV511 cameras, and is REQUIRED with OV518 cameras. It requires lots of CPU power, and reduces the image quality somewhat, though. If you want/need it, do the following: (NOTE: for OV518 cameras, substitute ov518_decomp for ov511_decomp ) 1. Make sure you installed the latest driver using the above instructions. The driver that comes with kernels and operating systems by default has no compression support. 2. Add the following line to your /etc/modules.conf . This will load the decompressor after ov511 is loaded, and unload the decompressor before ov511 is unloaded: above ov511 ov511_decomp 3. If you want compression enabled by default all of the time, add the following line to /etc/modules.conf: options ov511 compress=1 4. Load ov511.If you didn't make compression the default in /etc/modules.conf , load it with the compress=1 option (modprobe ov511 compress=1). If it is already loaded, remove it first with " rmmod ov511" 5. When you unload ov511, you must do it with modprobe (modprobe -r ov511). With rmmod, you will get "ov511: Device or resource busy", since it doesn't remove ov511_decomp automatically. <snip> ...it looks like there should be another module called 'ov511_decomp', but is currently missing from 'linux-image-2.6.16-2-686'. Maybe this 'ov511_decomp' module can be added?
