Remarks
This attribute applies to source nodes (MF_TOPOLOGY_SOURCESTREAM_NODE). The attribute is optional.
This attribute requires the MF_TOPONODE_WORKQUEUE_ID and MF_TOPONODE_WORKQUEUE_MMCSS_CLASS attributes on the same node.
The value of the attribute is the relative thread priority of the work queue for this branch of the topology. The Multimedia Class Scheduler Service (MMCSS) uses the relative priority when it sets the thread priority. For more information, see AvSetMmThreadPriority.
