MF_SD_MUTUALLY_EXCLUSIVE attribute

Specifies whether a stream is mutually exclusive with other streams of the same type.

Data type

UINT32

Get/set

To get this attribute, call IMFAttributes::GetUINT32.

To set this attribute, call IMFAttributes::SetUINT32.

Applies to

IMFStreamDescriptor

Remarks

If this attribute is TRUE (nonzero), the stream is mutually exclusive with other streams of the same type, such as audio or video, within the same presentation. For example, if an AVI file contains multiple audio streams, they are marked as mutually exclusive, because only one audio stream should be played at one time.

The default value is FALSE.

Note  This attribute is not used for Advanced Systems Format (ASF) files, which have a more sophisticated way to represent mutual exclusion criteria. For more information, see IMFASFMutualExclusion.

The GUID constant for this attribute is exported from mfuuid.lib.
