The FillBuffer method fills a media sample with data.
Syntax
virtual HRESULT FillBuffer(
IMediaSample *pSample
) PURE;
Parameters
pSample
Pointer to the sample's IMediaSample interface.
Return Value
Returns an HRESULT value. Possible values include those shown in the following table.
| Value | Description |
| S_FALSE | End of stream |
| S_OK | Success |
Remarks
The derived class must implement this method.
The media sample given to this method has no time stamps. The derived class should call the IMediaSample::SetTime method to set the time stamps. If appropriate for the media type, the derived class should also set the media times, by calling the IMediaSample::SetMediaTime method. For more information, see Time and Clocks in DirectShow.
Return S_FALSE at the end of the stream. This causes the CSourceStream class to send the end-of-stream notification and halt the buffer processing loop. See CSourceStream::DoBufferProcessingLoop for more information.
