Hello,

I need a way to start playing a video in fullscreen, without the user having to deal with the video player UI. I'm trying to do this:

video = 'path\to\my\video.avi';
videoReader = VideoReader(video);
fps = get(videoReader, 'FrameRate');
disp(fps); % the fps is correct: it's the same declared in the video file properties
currAxes = axes;
while hasFrame(videoReader)
  vidFrame = readFrame(videoReader);
  image(vidFrame, 'Parent', currAxes);
  currAxes.Visible = 'off';
  pause(1/videoReader.FrameRate);
end

The problem is that the video does not play at the correct speed: it seems slower and not smooth. Also, I need audio as well. What's the correct way to play a video in MATLAB without exposing the player UI to the user?

Thank you in advance for your help. :)

MATLAB has no mechanism to play both and video from a video. There have been suggestions about using:

MMPLAY which is a user submission
Use VLC Player's ActiveX plugin within a MATLAB GUI.

Thank you for your answer: mmplay works! Do you know if it's possible not to stop the MATLAB program execution while mmplay is playing the video? Thanks again!

If you have Windows, you can use the Windows Media Player:

winopen('rhinos.avi');
