IMediaPosition::get_CurrentPosition method (control.h)
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The get_CurrentPosition method retrieves the current position, relative to the total duration of the stream.

[out] REFTIME *pllTime

Remarks
This method returns the current position that playback has reached. The value includes adjustments for the playback rate and starting time. For example, if the start time is 5 seconds, the playback rate is 2.0, and you run the graph for four seconds, the current position is 5 + (4 x 2.0) = 13.0 seconds.
If the graph is paused or stopped, the current position is the point at which playback will resume.
