ITMedia::put_FormatCodes method

[ Rendezvous IP Telephony Conferencing controls and interfaces are not available for use in Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The RTC Client API provides similar functionality.]

The put_FormatCodes method sets the list of media payload format codes. The variant contains a SAFEARRAY of BSTRs. Each BSTR within that array is a format code string.

Syntax

HRESULT put_FormatCodes(
  [in] VARIANT NewVal
);

Parameters

NewVal [in]

List of media payload format codes.

Return value

This method can return one of these values.

Return code	Description
S_OK	Method succeeded.
E_INVALIDARG	The NewVal parameter is not valid.
E_OUTOFMEMORY	Insufficient memory exists to perform the operation.
E_FAIL	Unspecified error.
E_NOTIMPL	This method is not yet implemented.

Remarks

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.
