I'll try to look in the logs after I've installed the new kernel (I'm currently on 0.8.x/2.4.12), but as far as I can remember, it didn't give any error. The thing is, it always gives this error for the very first frame I try to capture. So either everything goes well (80-90%), or the first buffer's VIDIOCSYNC gives errno = EIOERR (10-20%). > > One last thing, do I need to do ioctl(fd, VIDIOCMCAPTURE, &1); to > > capture, or is VIDIOCMCAPTURE only useful for enabling/disabling > > the video overlay display? > > VIDIOCMCAPTURE queues requests, VIDIOCSYNC dequeues the finished ones. I actually meant VIDIOCCAPTURE, Rofl already mentioned that this only control overlay and has not that much to do with capture....
