To be honest, I didn't test this (as I didn't have 64-bit kernel available), but the fix was quite trivial. Basically I only had to change one unsigned long back to u32 as the DMA addresses VINO uses are always 32-bit. Nothing else should prevent the driver from working in a 64-bit environment. > > It looks exactly like the patch you gave me for testing a few days ago > and that did not work...

The compatibility layer doesn't forward certain ioctls to the driver and only returns an error code. Also please remember to download the newest version (0.7.1) of the patched camsource from my web page when testing the driver. The newest version has a couple of fixes which should allow the application to work with the driver even if VIDIOC_CROPCAP fails. But anyway the V4L ioctl compatibility layer needs to be fixed. http://www.mbnet.fi/~turja/vino/ Mikael Nousiainen
