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!
