how to player video

[zhoukailove]

I use the image control to play the video frame by frame. but unsuccessful
`
private string login;
private int time;
private int i;
private VideoCapture objCap;

private void ExecutePlayerCommand()
{
objCap = new VideoCapture();

    objCap.Open(@"C:\Users\86131\Desktop\202203021045.mp4");
    // ShowMove();
    time = (int)Math.Round(1000 / objCap.Fps);
    var thread = new Thread(ShowMove);
    thread.Start();
}

private void ShowMove()
{
if (objCap.IsOpened())
{
while (true)
{
Mat frame = new Mat();
MemoryStream ms = new MemoryStream();

            var readed = objCap.Read(frame);
            if (frame.Empty())
            {
                MessageBox.Show("over");
                return;
            }


            Bitmap b = BitmapConverter.ToBitmap(frame);
            b.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
            byte[] bytes = ms.GetBuffer();
            ms.Close();
            BitmapImage image2 = new BitmapImage();
            image2.BeginInit();
            image2.StreamSource = new MemoryStream(bytes);
            image2.EndInit();
            Image = image2;
            Thread.Sleep(time);
            i += 1;
        }
    }
    else
    {
        objCap.Release();
    }
}`
