Is it possible to view multiple videos at the same time (and being able to process it with custom code)?

figure(1)
movegui([0,300]);
figure(2)
movegui([700,300]);
vidObj = VideoReader('homer1.mp4');
vidObj2 = VideoReader('homer2.mp4');
while hasFrame(vidObj) && hasFrame(vidObj2)
vidFrame = readFrame(vidObj);
vidFrame2 = readFrame(vidObj2);
set(groot,'CurrentFigure',1);
imshow(vidFrame)
set(groot,'CurrentFigure',2)
imshow(vidFrame2)
end
I'd like to be able to read two video files, process them in real time and show them in seperate figures. The code above does not really work (I get the error message:"Error using VideoReader/initReader (line 734) Failed to initialize internal resources."), but I'm sure there are better methods to watch videos. What is the best way to show such videos (while they are processed)? I attached the video files to this question.
Thanks in advance

Hi
You can combine the frames of both the videos and visulaize them in loop using imshow function. For example, consider the below example:
v = VideoReader('xylophone.mp4');
while hasFrame(v)
frame = readFrame(v);
I = [frame frame];
imshow(I)
end
Hope it help!
