Hi, your code is almost correct only you have add some pause() between every frame otherwise you won’t be able to see all the frames. The pause time should be ideally 1/FrameRate to view the video in its original speed. Refer to the code below.
vidReader = VideoReader('rhinos.avi'); % Read your video here
vidPlayer = vision.DeployableVideoPlayer;
while(hasFrame(vidReader))
I = readFrame(vidReader);
step(vidPlayer,I);
pause((1/vidReader.FrameRate)); % pause of value (1/FrameRate)
end
Or else if you only want to play the video you can use the function implay().
implay('rhinos.avi'); % Read your video here
And hit the ‘Play’ button.
Hope this helps!
