MF_SESSION_GLOBAL_TIME attribute
Specifies whether topologies have a global start and stop time.
Data type
UINT32
Treat as a Boolean value.
Remarks
You can set this attribute when you create the media session by using the pConfiguration parameter of the MFCreateMediaSession or MFCreatePMPMediaSession function.
If this attribute is present and nonzero, then all topologies passed to the Media Session must have the MF_TOPOLOGY_PROJECTSTART and MF_TOPOLOGY_PROJECTSTOP attributes. These attributes specify the start and stop times for the topology relative to the entire presentation.
If this attribute is absent or FALSE, the topologies must not have the MF_TOPOLOGY_PROJECTSTART or MF_TOPOLOGY_PROJECTSTOP attribute.
Use this attribute to create editing sequences. For more information, see Sequence Presentation Times.
The GUID constant for this attribute is exported from mfuuid.lib.
