MF_TOPONODE_STREAMID attribute

The stream identifier of the stream sink associated with this topology node.

Data type

UINT32

Remarks

This attribute applies to output nodes (MF_TOPOLOGY_OUTPUT_NODE).

When the Media Session loads the topology, it queries the media sink for a stream sink with the specified identifier. If that fails, it attempts to add a new stream sink to the media sink.

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