Hello, The v4l2 controls for my cam give the interval 0-6000 for exposure, but anything over 4000 gives black screen. The automatic exposure control (software, the cam has no hardware exp control) starts as usual at something low, if there is not enough light the exp control pumps up the exposure a little - just as it should be, but the when exposure gets over 4000 the screen gets black and exp control pumps it all the way to 6000 (which is black as well). The workaround is to start v4l2ucp, to turn off auto exposure, then set exposure to 3999. But that is still a bit dark, so I set the gain at 6 or 8 and that gives video of good quality. The driver at http://groups.google.com/group/microdia worked well. The problems started when I switched to gspca (the driver at that google group was merged in gspca). I have some experience with C, but have never done any serious source diving. Can someone guide me trough. Maybe a personal exchange of mails will be better suited until a patch is ready.
