Camera Settings

I now have my second usb camera working (sort of).
I get the streaming video..however...

The picture is poor because the brightness, contrast, hue, and Colour are wrong.

If I change them, it saves, then reverts to another # in all four categories.

I have run select statements on the table and see it change, but the representation in the table doesn't match the video settings.

One camera one it works great. The second camera is a Quick Cam Express II .
Any ideas?

There was once an issue with the values not getting saved in the database. Might be possible that it broke again. You can try setting the values in the database via the command line or if you have webmin or phpmyadmin you can use those to place the values in the db.

Some drivers, especially usb ones, don't actually let you change these values though they appear to. This is because they are managing them automatically and you have to turn that off first. Which driver are you using?

I agree that the driver is automatically doing it, because it seems to change with light...

Both cameras are using the sp driver:

That's not one I've used but in the cpia and/or ov511 drivers there was a /proc device that you could cat to to turn off auto settings for these things. Plus I assume there probably is a parameter you can add to the driver in modules.conf but I don't know what it might be for that driver.
