IWMCodecOutputTimestamp::GetNextOutputTime Method
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 or IMFTransform::ProcessOutput to get the sample.
Syntax
HRESULT GetNextOutputTime(
[out] REFERENCE_TIME *prtTime
);
Parameters
- prtTime [out]
Address of a variable that receives the presentation time of the next sample.
Return Value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |

Remarks
This method is important when decoding video using frame interpolation, because the rendering application cannot predict the time stamps of interpolated frames.
