Motion - Support Question 2007x 01x 11x 193352

Logitech "RightLight"

Question

Hi

I finally got Motion working, and have started capturing images from my Logitech QuickCam Pro 5000 (which I think uses v4l2).

This webcam features "RightLight" technology, and have two of these cameras - one running on a windows machine, and another under Motion (under Fedora Core 6).

At the moment, both cameras are pointing outside, in the same direction so both show the same picture.

Under Windows, the "RightLight" seems to work well, as it gets darker outside the brightness compensates automatically, and a good picture is visible even when quite dark outside (until it goes very dark of course).

However, under Linux, the same camera shows a much darker picture quite early on. Looking at the outputs side by side (in early evening when it is "half dark" outside), the windows-generated picture still looks almost normal (like daylight) while the Linux one is almost completely black.

Do you know why this is ? I would have thought "RightLight" was a function of the webcam, and independent of the software/drivers using it.

Maybe there are some settings in Motion that are overriding the camera ?

The only settings I have changed from default are to do with image size (640x480), the periodic image generation timing, and destination filenames.

As per my question the other night, this is version 3.2.8 checked out from subversion, with the v4l2 patch applied.

Any ideas ? Thanks!

Follow up

Your camera is using uvcvideo , http://linux-uvc.berlios.de/ so maybe that feature that you're talking about is not yet implemented.

Please try to ask developer of your driver , they will ask your better than me .

btw , you don't need anymore to use any patch to use motion with V4L2 support , because the patch is included in current svn version.
