IWMCodecOutputTimestamp::GetNextOutputTime
Queries the decoder for the time stamp of the upcoming output sample. Use this method if you need to know the time of the sample before calling IMediaObject::ProcessOutput to get the sample.
Syntax
HRESULT GetNextOutputTime( REFERENCE_TIME* prtTime );
Parameters
prtTime
[out] Address of a variable that receives the presentation time of the next sample.
Return Values
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
| S_OK | The method succeeded. |
Remarks
This method is important when decoding video using frame interpolation, because the rendering application cannot predict the time stamps of interpolated frames.
