I did real-time processing with a video, what you can do is take out the frames per second of the video and with a "tic toc" to save the processing time of your code, and with that time obtained skip all the following frames at that time of such that the application obtaining real-time data works for you :

v = VideoReader(filename);
fr=v.FrameRate;
k=1;
while k<v.NumFrames
    frame = read(v,k);
    tic 
    %your processing here

    time=toc;
    k=k+ceil(time*fr);
end
