UINT32

Treat as a Boolean value.

Remarks

This attribute applies to output nodes (MF_TOPOLOGY_OUTPUT_NODE).

If the value of this attribute is TRUE, the Media Session does not preroll any data to the media sink, even if the media sink exposes the IMFMediaSinkPreroll interface. If the value is FALSE, the Media Session prerolls data if the media sink implements IMFMediaSinkPreroll. The default value is FALSE.

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