Have you tried running it under X?

[mahdichi]

yes, i try guvcview but when i run it, it came with error that Unable to open device. i try run it with command line and set device to be /dev/video1 but it doesn't work to.

maybe this will give some info, it also saves to file, so it does not depend on output graphics working:

try sudo fswebcam -v -d v4l2:/dev/video1 and try sudo fswebcam -v -d v4l2:/dev/video1 --list-inputs

hi, i try your command with usb webcam and it work fine but in Cubian r5 there is no csi kernel driver.

it's be good if add sun4i-csi1 module in next update.
