This method calls the CPosPassThru::GetMediaTime method to retrieve the most recent position. If GetMediaTime fails, the method calls IMediaSeeking::GetCurrentPosition on the connected pin.

The GetMediaTime method fails by default in the base class. If your filter caches the current position, override GetMediaTime to return the cached value.
