Hello, It seems that diamondback OpenCV packages have broken camera capture. We have observed the problem on Ubuntu 10.04, 10.10 and 11.04. A minimal test case is attached to this email. This issue is being discussed on answers.ros.org, but it seems that the packagers have not taken action yet to fix the problem: http://answers.ros.org/question/1128/opencv-videocapture-not-working-in-diamondback This seems a major bug to me, is there a plan to fix it in the short term? Thank you; have a nice week-end, Stéphane Magnenat -- Dr Stéphane Magnenat http://stephane.magnenat.net
