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!
