  virtual int PlayVideo(const uchar *Data, int Length);
       ///< ...

  virtual int PlayAudio(const uchar *Data, int Length, uchar Id);
       ///< ...
       ///< PlayAudio() shall process the packet either as a whole (returning

       ///< ...

By definition these two functions shall write "all or nothing".
So the higher level functions needn't handle any partially written data.
