I am a new Stack Overflow user and haven’t used to how things work here. So please be patient with me if I do anything wrong. So, I had a homework test for job-hunting. I did it but apparently my result was not good enough and I did not pass. However, I don’t know what I did wrong. Please review my code so that I understand what I did wrong.

Homework Test Background

Consider the following two interfaces:

1. IFrameCallBack

public interface IFrameCallback
{
public void FrameReceived( IntPtr pFrame, int width, int height );
}

• FrameReceived is a callback method that will be called by a native library every time a new frame is available from an image capture device i.e. a camera.
• pFrame is the pointer to the raw bytes of the frame, width and height denotes the size of the frame in pixels.
• pFrame is reused by the native library to store the next frame as soon as the callback completes.
• This callback method is guaranteed to be called periodically depending on the frame rate configured on the capture device, in this case it is 30FPS.

2. IValueReporter

public interface IValueReporter
{
public void Report( double value );
}

• Report is a callback method that is implemented by an external library that will plot the given
  value in a real-time chart.

Homework Test Instruction

Write a program to fetch the frame from the camera, calculate the average pixel value, and stream back the calculated value.

Please and thank you.

I coded according to the homework test background and instruction, but the result wasn’t good enough for the potential employer.
