Hi Gerd, Is that possible to use any v4l function call to directly access (read/write) bt878 GPIO? Which function? Any documentation or which source code I should look at through to know the API interface?

But there are also some grabber cards with a PCI-PCI bridge and 4 bt8x8 chips behind it. These cards will show up with 4 v4l(2) devices which can be used in parallel (at least as long there is enough PCI bandwidth ...). Gerd -- /join #zonenkinder
