MF_EVENT_START_PRESENTATION_TIME_AT_OUTPUT attribute

The presentation time at which the media sinks will render the first sample of the new topology.

Data type

UINT64

Treat as a LONGLONG value.

Remarks

If any pipeline objects in the previous topology buffered data, this value will be slightly less than the value in the MF_EVENT_PRESENTATION_TIME_OFFSET attribute, because the sinks must render the buffered data.

This attribute is a signed value, although it is stored as a UINT64.

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