You can use implay(): https://www.mathworks.com/help/releases/R2020b/images/ref/implay.html to play video.

You can also make your own GUI as shown in following code

v = VideoReader('xylophone.mp4');
figure();
ax = axes();
frame = readFrame(v);
im_frame = imshow(frame, 'Parent', ax);
while hasFrame(v)
    im_frame.CData = readFrame(v);
    drawnow
end

MATLAB: How to add a marker to only specific frames in a video

Hi,

As you know the indices of frames to mark, you can use readFrame function to read those frames from video and then use insertMarker function to add marker to the frame at specific position. If you want to add markers to frames with indices 2, 4 and 6, your code will look something like this:

% Create object to read video
v = VideoReader('xylophone.mp4');
% Frames to which marker must be inserted
markFrames = [2 4 6];
frameidx = 0;
videoPlayer = vision.VideoPlayer;
while hasFrame(v)
    % Read next video frame
    frame = readFrame(v);
    frameidx = frameidx + 1;
    % Check if index of frame is to be marked or not
    if any(ismember(markFrames, frameidx))
        markedFrame = insertMarker(frame, [50 50]);
        videoPlayer(markedFrame);
    else
        videoPlayer(frame);
    end
end

Hope this helps.
