как исправить ошибку ArgumentOutOfRangeException в строке

while((read = stream.Read(buffer, total, 1000)) != 0)

Полный текст метода:

private void getFrame()
{
    string sourceURL = "https://geocam.tv/streamer/2222.mjpg";
    byte[] buffer = new byte[1280 * 800];
    int read, total = 0;
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(sourceURL);
    WebResponse resp = req.GetResponse();
    Stream stream = resp.GetResponseStream();
    while((read = stream.Read(buffer, total, 1000)) != 0)
    {
        total += read;
    }
    Bitmap bmp = (Bitmap)Bitmap.FromStream(new MemoryStream(buffer, 0, total));
    pictureBox1.Image = bmp;
}

Я хочу транслировать видео из странички https://geocam.tv/streamer/2222.mjpg

воспользовался MJPEG Decoder

public partial class Form3 : Form
{
    MjpegDecoder _mjpeg;
    public Form3()
    {
        InitializeComponent();
        _mjpeg = new MjpegDecoder();
        _mjpeg.FrameReady += mjpeg_FrameReady;
    }
    private void button1_Click(object sender, EventArgs e)
    {
        _mjpeg.ParseStream(new Uri("https://geocam.tv/streamer/2222.mjpg"));
    }
    private void mjpeg_FrameReady(object sender, FrameReadyEventArgs e)
    {
        pictureBox1.Image = e.Bitmap;
    }
