When compiling a standalone application, how can I include the class VideoReader?

1 view (last 30 days)
VideoReader is a class definition in MATLAB toolbox. The toolbox should be included in MATLAB compiler, but it seems that this class definition is not included. I tried to add the M file into the 'files required', but I was not let to do that. So how can I add the class VideoReader?

I wrote this code to test the function of VideoReader. It does work in GUIDE without error. I use this 'readFrame' here instead of 'read' as MATLAB recommends. Both work well in MATLAB, but neither is working for compiling. Do you have any idea about this?
function pushbutton1_Callback(hObject, eventdata, handles)
[VideoName,VideoPath,FilterIndex] = uigetfile('*.avi','Open AVI file');
readerobj = VideoReader(VideoName);
frame = 1;
while hasFrame(readerobj)
vidFrame = readFrame(readerobj);
I(:,:,frame,:) = vidFrame;
frame = frame + 1;
guidata(hObject, handles);

Change this:
readerobj = VideoReader(VideoName);
to this:
readerobj = VideoReader(fullfile(VideoPath, VideoName));
Always provide the full video file path, otherwise the compiled software cannot find the video file. The Matlab working paths are different form those of a compiled application.
