Hi, I've cross compiled UVC driver for ARM arch, using kernel 2.6.14. I'm using uvccapture to get snapshot by a FinePix E550 camera in webcam mode.
After the command ./uvccapture -v , the output is: Using videodevice: /dev/video0 Saving images to: snap.jpg Image size: 320x240 Taking snapshot every 0 seconds Taking images using mmap format asked unavailable get width 352 height 288 Resetting camera settings ioctl querycontrol error 22 ioctl querycontrol error 22 ioctl querycontrol error 22 ioctl querycontrol error 22 ioctl querycontrol error 22 Camera brightness level is -1 ioctl querycontrol error 22 Camera contrast level is -1 ioctl querycontrol error 22 Camera saturation level is -1 ioctl querycontrol error 22 Camera gain level is -1 Saving image to: snap.jpg I get the snap, but there are these errors about the camera settings. How can I fix it? Thank you for any suggestion. Best Regards, Claudio Montemaggiore
