As discussed recently, the OutputCallback in IConnectionCallbackHandler doesn't make sense. The buffer is not meant to contain data, it's a source of unused buffers. The else portion of the if-else block in MMALConnectionImpl's NativeConnectionCallback method invokes the callback, but the buffer Length is always zero, so it is never actually executed.
