Out of memory error

Using AForge.Video.DirectShow
AForge.Video.DirectShow
to integrate a QR Code scanner in my WPF App but whenever the scanner is open it crashes in 15 seconds due to out of memory error as it reaches 4gb memory usage and I'm not able to exactly pinpoint the reason why its happening, BitmapToImageSource()
BitmapToImageSource()
throws the out of memory error.
