CRendererPosPassThru.RegisterMediaTime method (Ctlutil.h)

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.

Return code Description
S_OK
 Success.
VFW_E_MEDIA_TIME_NOT_SET
 The sample is not time-stamped.

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.
