[Spca50x-devs] VIDIOCGPICT and VIDIOCSPICT ioctl failing




Hi all,
I am using logitech usb web camera and spcaview-20061208  in application
side ...
And on my embeded board side I am using gspcav1-20070508 driver , then I am
geting video but having poor quality .... I think its because of
VIDIOCGPICT and VIDIOCSPICT ioctl failing ......( I checked the Error code
it  is "ESPIPE :Illegal Seek")
Can you tell me what should I do to resolve this problem ...???
I am using linux kernal 2.6.20 version ....... .......




Thanks,
Amol Pise
