I'm working on getting a USB camera that comes standard with the "Evolution Robotics 1" robot working under Linux for an open source project (http://PyroRobotics.org). I've email Mark McClelland from the OvCam driver project, but thought I'd see if anyone has any pointers here.
The camera is a variant of the ov511, specifically the ov518 variety that uses compression, apparently. The camera is the Krittercam from Irez.com. I'm working under RedHat 9. Mark's FAQ correctly noted that I needed the ov518_decomp, but after installing that, I get:
% xawtv can't open /dev/video0: Message too long v4l-conf had some trouble, trying to continue anyway v4l2: open /dev/video0: Message too long ...
which suggests to me that something else needs to be updated, maybe something for Video4Linux? Maybe I need to use a different driver, maybe the ov7x20?
I'm running the 1.65 version of the OvCam driver, ov511-1.65. The 2.x versions required more changes than I could make (changing kernel options, for example). If you have time to suggest a fix, I'd very much appreciate it. I've included information (proc, uname, lsmod) that Mark suggests below.
Thanks for any hints!
