Specifies the duration of a byte stream, in 100-nanosecond units.
Treat as a LONGLONG value.
This attribute is optional. If the object that creates the byte stream can determine the duration, it can set this attribute. (For example, in a network stream, the duration might be part of the session description.)
To get the attribute value, call QueryInterface on the byte stream to get a pointer to the IMFAttributes interface.
This attribute is a signed value, although it is stored as a UINT64.
The GUID constant for this attribute is exported from mfuuid.lib.
