Remarks

This attribute specifies the position in the source where playback stops, in 100-nanosecond units, relative to the start the source. If the attribute is not set, playback stops at the end of the source. For example, to stop playback at the 5-second mark, set this attribute to 50000000. Set the attribute on the source nodes in the topology (nodes with type equal to MF_TOPOLOGY_SOURCESTREAM_NODE). Set the attribute before calling IMFMediaSession::SetTopology.

Note

If you manually insert a decoder into the topology, you must also set the MF_TOPONODE_MARKIN_HERE and MF_TOPONODE_MARKOUT_HERE attributes on the decoder node.

After the topology is set, setting this attribute has no effect.

This attribute is a signed value, although it is stored as a UINT64. However, negative values are not meaningful.

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