[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The SetEnableUDP method enables or disables UDP.

Syntax

HRESULT SetEnableUDP(
  [in] BOOL fEnableUDP
);

Parameters

[in] fEnableUDP

Boolean value that is True if UDP is to be enabled. Set this to true if the reader can use UDP-based MMS streaming when selecting a protocol for streaming.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
E_INVALIDARG	NULL or invalid argument passed in.

Remarks

This setting applies only to a protocol rollover or MMS://URL. Even if this setting is disabled, the application can still specify an explicit MMSU://URL and stream MMS via TCP successfully.

For more information, see the Remarks section of IWMReaderNetworkConfig::ResetProtocolRollover.
