1. how are you setting the callback?

interface ICaptureCallback
{
   // other stuff removed
   void ReturnFrame(byte[] frameData);
}

2. what is (or would be) the prototype of the callback in native C++?

Luc Pattyn wrote:

3. who is allocating and freeing the (native?) buffer that the callback is assumed to consume?

array<Byte>^ jpegData = gcnew array<Byte>(Width * Height * 3);
  Marshal::Copy(IntPtr(pRgbFrame->data[0]),jpegData,0,Width * Height * 3);
  m_callback->ReturnFrame(jpegData);
  jpegData = nullptr;

4. don't you close the file (m_outputWriter and m_outputFile)? without it, the stream grows bigger and bigger.
