CRendererPosPassThru.ResetMediaTime method
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 ResetMediaTime method resets the cached time stamps to zero.
Syntax
HRESULT ResetMediaTime();
Parameters
This method has no parameters.
Return value
Returns S_OK.
Remarks
The filter should call this method whenever the time stamps cached by the CRendererPosPassThru::RegisterMediaTime method become invalid. Specifically, it should call this method in response to the IPin::EndFlush and IMediaFilter::Stop methods.
After this method is called, the CRendererPosPassThru::GetMediaTime method returns zero for the start and end times.
