If you are having trouble using the Image Acquisition Toolbox™ software with a supported Macintosh video acquisition device, follow these recommended troubleshooting steps:
Verify that your image acquisition hardware is functioning properly.
You can verify that your hardware is functioning properly by running the WebCam application that came with OSX, for example, Photo Booth or iMovie.
If you can start the utility, run the utility, and close the utility without encountering any errors, then the toolbox should be able to operate with your image acquisition device. If you encounter errors, resolve them before attempting to use the toolbox with the device.
With previous versions of the Image Acquisition Toolbox™, the files for all of the adaptors were included in your installation. Starting with version R2014a, each adaptor is available separately through MATLAB® Add-Ons. In order to use the Image Acquisition Toolbox, you must install the adaptor that your camera uses, in this case, the OS Generic Video Interface support package. See Image Acquisition Support Packages for Hardware Adaptors for information about installing the adaptors.
Verify that you can access your device through the Macintosh Video Adaptor.
Make sure the camera complies with the AV Foundation Libraries.
The Macintosh Video Adaptor is a generic interface and should only be used if you do not have a more specific adaptor to use with your device. If your device is a DCAM or FireWire device, use the DCAM adaptor. Only use the Macintosh Video Adaptor if there is no more specific option for your device.
Make sure you have Apple AV Foundation Libraries installed on your computer. If you do not have it installed, you can download it.
The OS Generic Video Adaptor on Mac (
now uses Apple AV Foundation Libraries, instead of QuickTime, starting
with R2016b. The use of the Macintosh Video adaptor previously required
that you have QuickTime installed on your computer. QuickTime is no
longer required. Now you need to have the AV Foundation Libraries
installed on your computer.
