I have an AVT GE680 GigE camera on Win 7 64 bit and MATLAB 2012b with image acquisition toolbox. I am currently using AVT's custom filter driver provided with their VIMBA SDK. This driver interfaces with MATLAB via the GenTL adapter. I can open the camera, preview the video, set the ROI and other properties. However, matlab does not update the AcquisitionFrameRateLimit property. It remains at whatever value it initially detected when opening the video device, which is usually 60fps. However, in my application, I want to run the camera at its max frame rate, so I need to query the frame rate limit so that I can set the fame rate to this value. I have been working with the AVT technical support to get the camera working with their filter driver, but they claim that this last issue is matlab specific. Any thoughts?
