Video files app designer

How do I add an option to upload video files to app designer?

Hi, I'm looking at this solution as well.

However, I found an alternative way to do it.

v = VideoReader('song.mp4'); 
while hasFrame(v)
        readFrame(v);
        numFrames = numFrames + 1;
end         

 for i=1:1:length(v)

       frame = read(v,iter2);
       imshow(frame,'Parent',app.UIAxes2);
       drawnow;
end

you may use button or axes to host image.

Hi @T.A.S.,

Video files can be uploaded to App Designer using "uigetfile" function. It opens a modal dialog box that lists files in the current folder. To ensure that user can upload video files only, the "filter" argument can be used as follows:

videoFilter = {'*.mp4;*.avi;*.mov;*.mkv'}; 
% Open the file selection dialog 
[filename, pathname] = uigetfile(videoFilter, 'Select a Video File'); 

This function returns file name which can be used further according to the requirements.

You can know more about "uigetfile" function using this documentation:

Hope this helps you!
