IMFSample::SetSampleDuration Method

Sets the duration of the sample.

Syntax

HRESULT SetSampleDuration(
  [in]  LONGLONG hnsSampleDuration
);

Parameter

• hnsSampleDuration [in]
  Duration of the sample, in 100-nanosecond units.

Rückgabewert

Ist Methode erfolgreich, wird "S_OK" zurückgegeben. Andernfalls wird ein HRESULT-Fehlercode zurückgegeben.

Hinweise

This method succeeds if the duration is negative, although negative durations are probably not valid for most types of data. It is the responsibility of the object that consumes the sample to validate the duration.

The duration can also be zero. This might be valid for some types of data. For example, the sample might contain stream metadata with no buffers.

Until this method is called, the IMFSample::GetSampleDuration method returns MF_E_NO_SAMPLE_DURATION.
