1. To draw a video on PictureBox, you need to add control to the form. Set BackColor property to Black and SizeMode property to StretchImage.
2. Add a bool class member called applyingPictureBoxImage on Start button code set applyingPictureBoxImage to false before starting capture or playback.
3. Implement the OnVideoFrameBitmap event to draw the frame.
private void VideoCapture1_OnVideoFrameBitmap(object sender, VideoFrameBitmapEventArgs e)
{
if (applyingPictureBoxImage)
{
return;
}
applyingPictureBoxImage = true;
var image = pictureBox1.Image;
pictureBox1.Image = new Bitmap(e.Frame);
image?.Dispose();
applyingPictureBoxImage = false;
}
4. Add PictureBox clearing to the Stop button code. Code should be called after SDK control Stop method call.
while (applyingPictureBoxImage)
{
Thread.Sleep(50);
}
pictureBox1.Image?.Dispose();
pictureBox1.Image = null;
