All CODEC messages are passed to a CODEC using this interface. The syntax for a direct CODEC procedure call is shown below:

typedef LONG (APIENTRY CODECPROC)
                                (PHCODEC phcodec,
                                 USHORT usMsg,
                                 LONG lParam1,
                                 LONG lParam2);
