IWMPlayerTimestampHook::MapTimestamp method (wmdxva.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The MapTimestamp method is called by the WMV Decoder DMO to enable the source filter to provide the decoder with a time stamp. The decoder applies the time stamp to the sample before delivering the sample to the video renderer.
