        {
            VideoInputDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
            if (VideoInputDevices.Count != 0)
            {
                foreach (FilterInfo device in VideoInputDevices)
                {
                    comboBox1.Items.Add(device.Name);
                }

            comboBox1.SelectedIndex = 0;
        }
        private void start_Click(object sender, EventArgs e)
        {
            ChoosenVideoSoure = new VideoCaptureDevice(VideoInputDevices[comboBox1.SelectedIndex].MonikerString);
            ChoosenVideoSoure.NewFrame += new NewFrameEventHandler(video_NewFrame); ChoosenVideoSoure.Start();
            ChoosenVideoSoure.Start();

            {
                if (ChoosenVideoSoure.IsRunning)
                {
                    ChoosenVideoSoure.Stop();
                    pictureBox1.Image = null;
                }
            }
        }
        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {

                    ChoosenVideoSoure.Stop();
                    pictureBox1.Image = null;
                }
            }
        }

        private void video_NewFrame(object sender, NewFrameEventArgs eventArgs)
        {
            Bitmap img = (Bitmap)eventArgs.Frame.Clone();
            pictureBox1.Image = img;
        }

        //close the device safely
        private void CloseVideoSource()
        {
            if (ChoosenVideoSoure != null)
            {
                if (ChoosenVideoSoure.IsRunning)
                {
                    ChoosenVideoSoure.Stop();
                    pictureBox1.Image = null;
                }
            }



    }
        private void record_Click(object sender, EventArgs e)
        {

        }

Hi,

You cannot do video processing directly on the media player control. Instead process the incoming video signal from the web cam. After that send those video stream to the browser control. During video play you can take a screen shot using c#.

Below is the link which explains about taking screen shot using c#,

Hi,

   By making use of ActiveX you can accomplish this. So windows media player comes with a browser plugin. using this you can play a video which is stored in your web application.

Here is a sample which you can make use of,







Here the text which is highlighted in red is place where you have to specify your link to the video file. For value you can use your physical path or an url to you media file.

This pulg-in works with Internet Explorer and mozilla.
