As a java developer I don't want to spam your mailing list. But Nemosoft put me in, so I just want to follow this thread. Of course I've to use JNI. But till now I didn't dive into kernel and driver stuff. Just happy I found an example which showed me the right ioctl-statement to get an imageframe from /dev/videoX. To precise my question. I'm notified about the plug-in of webcam. With this notification I get the information which device is associated with in usbdevfs (e.g. /proc/bus/usb/001/002). So how does the ioctl-statement have to look like to get a structure FOO filled with information I'm interessted in (e.g. /dev/video0 or /dev/video1)? And which type of structure FOO do I've to use? Can you give me an URL where I find the appropriate ioctl-statement and the needed structure documented?
