How to draw video on PictureBox?

1. Add PictureBox control to form. Set BackColor property to Black and SizeMode property to StretchImage.

​

2. Add bool class member called applyingPictureBoxImage. On Start button code set applyingPictureBoxImage to false before starting capture or playback.

​

3. Implement OnVideoFrameBitmap event to draw video frame on PictureBox.

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 Stop button code. Code should be called after SDK control Stop method call.

while (applyingPictureBoxImage)
            {
                Thread.Sleep(50);
            }

pictureBox1.Image?.Dispose();
pictureBox1.Image = null;
