Return code Description
Method is not supported.
NULL pointer argument.


This method is intended primarily for seeking in media streams that might have excessive latency, such as streams being sent over a network. The returned values indicate cached data that has already arrived, which can be easily seeked. It is assumed that seeking to values beyond these returned parameters will cause a delay while the application waits for the data to arrive.

All time values are expressed in the current time format. The default time format is REFERENCE_TIME units (100 nanoseconds). To change time formats, use the IMediaSeeking::SetTimeFormat method.
