I'm able to run the GUI code in MATLAB but when compiled to .exe and run it
I got the error Undefined function or variable 'imaqslgate'
I suppose Image Acquisition Toolbox is able to compile to .exe right?
Using MATLAB R2015a and build in webcam
function pushbutton1_Callback(hObject, eventdata, handles)
vid = imaq.VideoDevice('winvideo', 1, 'MJPG_640x480', 'ROI', [1 1 640 480], ...
'ReturnedColorSpace', 'rgb', ...
'DeviceProperties.Brightness', 0, ...
'DeviceProperties.Sharpness', 15);
videoPlayer = vision.VideoPlayer('Name','Camera Preview','Position',[510 320 660 520]);
videoFrame = step(vid);
Undefined function or variable 'imaqslgate'.
Error in imaq.internal.Utility.getDeviceList (line 26)

Imshow() To display video on the gui axes. Which I will do some object detection and display on the axes. This is just a simplified code.

There is also a workaround.

How are you running the executable? Within MATLAB using the ! operator, or double clicking it outside MATLAB? Either way, can you close MATLAB (if its running) or run IMAQRESET in MATLAB before running the exe? Just to make sure that the hardware is not in use.

Well i tried running the executable without MATLAB running and also IMAQRESET before closing MATLAB. Thank you anyway. Hope i can solve it or someone can provide me a simple executable with just 1 button to enable my camera.
