global videoFReader
faceDetector = vision.CascadeObjectDetector();
videoFReader = vision.VideoFileReader('test.avi');
videoPlayer = vision.VideoPlayer;
while ~isDone(videoFReader)
videoFrame = step(videoFReader);
step(videoPlayer, videoFrame);
end
axes(handles.axes1)
imshow(videoFReader);

global show_video; videoFReader = vision.VideoFileReader('test.mp4'); framert = 30; videoPlayer = vision.VideoPlayer; ax = handles.axes1; % assuming axes1 is used to disply in GUI while ~isDone(videoFReader) videoFrame = step(videoFReader); image(videoFrame, 'Parent', ax); set(ax,'Visible', 'off'); pause(1/framert); if show_video ~=1 % used as global so that can be set at controlling place. if show_video = 1 continuously play break end end release(videoPlayer);

You have axes in your gui, let's say they are called
axes1
(you can check the name of the axes by double clicking on it in GUIDE, then look for Tag.
Then the only thing you have to do is:
axes(handles.axes1);
implay(videohere);

Can I just say? Matlab support is attrocious. I can't believe how little help there is online for problems like this. The company should pay people to go online and provide solutions for people.

Check the my comment, this should work.
No, it doesn't work. It will play in the designated axes, but the use of a for-loop in conjunction with pause gives a very inaccurate frame rate.
