WxCam starts up OK but freezes if I select "Frame Size" from the Settings menu. The video is displayed in a very small window on startup. If I make the video full screen it does not freeze but it is obviously a small picture scaled up (very blocky pixels). All the required libraries are present. I will be glad to provide more info if you need it. The camera is the Logitech Quickcam Pro 9000. Here is the output: mike@Dell64:~$ wxcam Determining video4linux API version... Using video4linux 2 API VIDIOC_ENUM_FRAMESIZES: Invalid argument V4L2_CID_GAMMA is not supported Determining pixel format... pixel format: MJPEG Found V4L2_PIX_FMT_MJPEG pixel format pixel format: YUV 4:2:2 (YUYV) Found V4L2_PIX_FMT_YUYV pixel format If I select Frame Size from Settings menu here the picture freezes and the CPU become about 50% busy until I force quit. This may be unrelated but wxCam actually crashes if I use an older webcam. Cheese works OK so I know the camera works but it is a very old Logitech Quickcam - the new camera is the one I really care about for now. The crash occurs on startup and shows this output: mike@Dell64:~$ wxcam Determining video4linux API version... Using video4linux 1 API Determining palette format...
