readFrame

Create a VideoReader object for the sample video file xylophone_video.mp4.

v = VideoReader("xylophone_video.mp4");

Read all the frames from the video, one frame at a time.

while hasFrame(v)
    frame = readFrame(v);
end

Display information about the last frame returned by readFrame.

whos frame

  Name         Size                Bytes  Class    Attributes

  frame      240x320x3            230400  uint8              

Clear the VideoReader object.

clear v

Create a VideoReader object for the sample video file xylophone_video.mp4.

v = VideoReader("xylophone_video.mp4");

Specify to start reading frames at 2.5 seconds from the beginning of the video.

v.CurrentTime = 2.5;

Create an axes object to display the frame. Then continue to read and display video frames until no more frames are available to read.

currAxes = axes;
while hasFrame(v)
    vidFrame = readFrame(v);
    image(vidFrame,"Parent",currAxes)
    currAxes.Visible = "off";
    pause(1/v.FrameRate)
end

Clear the VideoReader object.

clear v

Create a VideoReader object for the sample video file xylophone_video.mp4. Then determine the width and height of the video.

xyloObj = VideoReader("xylophone_video.mp4");
vidWidth = xyloObj.Width;
vidHeight = xyloObj.Height;

Create a video structure array.

mov = struct("cdata",zeros(vidHeight,vidWidth,3,"uint8"),colormap=[]);

Read one frame at a time until the end of the video.

k = 1;
while hasFrame(xyloObj)
    mov(k).cdata = readFrame(xyloObj);
    k = k+1;
end

Size a figure based on the width and height of the video, and then play the video one time.

vf = figure(Position=[0 0 xyloObj.Width xyloObj.Height]);
imshow(mov(1).cdata,Border="tight")
movie(vf,mov,1,xyloObj.FrameRate)

Clear the VideoReader object.
