How do I add motion detection????

[roast247]

I wanted to add motion detection, so I had to add the reference "ref Bitmap image" but after adding that I get the error No overload for 'video_NewFrame' matches delegate 'NewFrameEventHandler'

        MotionDetector Detector;
        float viewmotion;

        private void mjpegStreamForm_Load(object sender, EventArgs e)
        {
            Detector = new MotionDetector(new TwoFramesDifferenceDetector(), new BlobCountingObjectsProcessing());
            viewmotion = 0;
        }

public void video_NewFrame(object sender, NewFrameEventArgs eventArgs, ref Bitmap image)     //<---------This is where I added it
       {
           viewmotion = Detector.ProcessFrame(image);

           time.Start();
           Bitmap img = (Bitmap)eventArgs.Frame.Clone();
           if (flag_rotate!=0)
           { 
           if (flag_rotate == 1) { img.RotateFlip(RotateFlipType.Rotate90FlipNone); }
           else if (flag_rotate == 2) { img.RotateFlip(RotateFlipType.Rotate180FlipNone); }
           else { img.RotateFlip(RotateFlipType.Rotate270FlipNone); }
           }
           if (flag_smooth == 1) { img = grayscale.Apply(img); }
           if (trackBar1.Value != 0) { img = br.Apply(img); }
           if (flag_flipX == 1) {img.RotateFlip(RotateFlipType.RotateNoneFlipX);}
           if (flag_flipY == 1) { img.RotateFlip(RotateFlipType.RotateNoneFlipY); }
           if (flag_sharpen == 1) { sharpen.ApplyInPlace(img);}
           if (flag_treshold == 1) {marker.ApplyInPlace(img); }
           if (flag_edge == 1) { rubovi.ApplyInPlace(img); }
           if (flag_dither == 1) {poster_filter.ApplyInPlace(img); }
           if (flag_invert == 1) { invert_filter.ApplyInPlace(img); }
           pbx_image.Image = img;
           time.Stop();
           lbl_time.Text = "Frame times: " + time.ElapsedMilliseconds+" ms";
           time.Reset();
       }

but on a button press I have the argument

        private void btn_playPause_Click(object sender, EventArgs e)
        {
            i++;
            if (i % 2 == 0)
            {
                this.btn_playPause.Image = ((System.Drawing.Image)(IPCams.Properties.Resources.icons8_circled_play_64));
                
                btn_capImage.Enabled = false;
                videoSource.SignalToStop();
                videoSource.WaitForStop();
                videoSource.Stop();
            }
            else
            {
                new Thread(() =>{
                Thread.CurrentThread.IsBackground = true;
                btn_capImage.Enabled = true;
                videoSource.Login = camUsername;
                videoSource.Password = camPassword;
                this.btn_playPause.Image = ((System.Drawing.Image)(IPCams.Properties.Resources.icons8_pause_button_64));
                videoSource.NewFrame += new NewFrameEventHandler(video_NewFrame);        //<---------This is where I have the problem
                videoSource.Start();
                }).Start();
            }
        }

Is there any way to get rid of this error? I just want motion detection to work!

if you write
new NewFrameEventHandler(video_NewFrame);
then
video_NewFrame(object sender, NewFrameEventArgs eventArgs, ref Bitmap image)
and
NewFrameEventHandler(object sender,NewFrameEventArgs eventArgs);
have to have the same arguments, but they are now different with Bitmap image.

if you write new NewFrameEventHandler(video_NewFrame); then video_NewFrame(object sender, NewFrameEventArgs eventArgs, ref Bitmap image) and NewFrameEventHandler(object sender,NewFrameEventArgs eventArgs); have to have the same arguments, but they are now different with Bitmap image.

How would I fix this? I won't be able to use motion detection unless Bitmap image is added
