Data type

UINT32

Treat as a Boolean value.

Remarks

This attribute applies to output nodes (MF_TOPOLOGY_OUTPUT_NODE).

If the value of this attribute is nonzero, the Media Session treats the media sink as a rateless sink, regardless of whether the media sink returns the MEDIASINK_RATELESS characteristic. If this attribute is not set, the media sink is assumed not to be rateless.

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