HRESULT get_FormatCodes( VARIANT *pVal );

| S_OK | Method succeeded. |
| E_POINTER | The pVal parameter is not a valid pointer. |
| E_OUTOFMEMORY | Insufficient memory exists to perform the operation. |
| E_FAIL | Unspecified error. |
| E_NOTIMPL | This method is not yet implemented. |
When a list of payload formats is given, this implies that all of these formats may be used in the session, but the first of these formats is the default format for the session. When the transport protocol is RTP, the format codes are RTP payload types.
