Detecting motion in a video

[kathsunil]

I'm writing a program that tracks a moving objects in a mpeg file. I'm using AForge.net. I'm new to c# and programming. I cannot get to play the video. For right now I want to play the video in a picture box and cature new and old video frame to compare the movements. Here is my code so far that does not work.

private void pictureBox1_Paint(object sender, PaintEventArgs e)
{
How do I get to play the video in the picture box?? }
 
private void button1_Click(object sender, EventArgs e)
{
videoSource = new FileVideoSource(videoFile);
//videoSource.
//videoSource.NewFrame += new AForge.Video.NewFrameEventHandler(video_NewFrame);
videoSource.Start();
 
 
}
 
private void video_NewFrame(object sender, AForge.Video.NewFrameEventArgs eventArgs)
{
Bitmap bitmap = eventArgs.Frame;
}
private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
 
openFileDialog.Filter = "Video (.mpeg)|*.mpeg|(.avi)|*.avi|ALL Files (*.*)|*.*";
 
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
videoFile = openFileDialog.FileName;
 
}
 
}
Help anyone please:kathsunil

Keep in mind that a video is a series of still frames. You don't drop a video control onto your dialog and walk away. You have to handle each frame as it comes in. Each time you get a still frame, put that frame in the your picture box. You don't have do override the picturebox's Paint event. Try replacing line 17 with this.

 pictureBox1.Image = eventArgs.Frame;

Thanks you
you have been very helpful to me. I had invested a lot of time trying to solve that.
Thank you again.
