CRendererPosPassThru.RegisterMediaTime method (Ctlutil.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 RegisterMediaTime method caches the time stamps from the current sample.

Syntax

HRESULT RegisterMediaTime(
   IMediaSample *pMediaSample
);

Parameters

pMediaSample

Pointer to the IMediaSample interface of the sample.

Return value

Returns an HRESULT value. Possible values include those listed in the following table.

Remarks

This method stores the time stamps from the current sample. The CRendererPosPassThru::GetMediaTime method retrieves the same values.

The filter should call this method for each sample that it receives. The method is overloaded to accept either a pointer to the sample, or the time stamp values themselves.
