IWMReaderAdvanced2::StopBuffering method (wmsdkidl.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The StopBuffering method requests that the reader send the WMT_BUFFERING_STOP message as soon as possible.

Syntax

HRESULT StopBuffering();

Return value

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Remarks

The reader responds to the request to stop buffering only if it is currently buffering data. This means it has sent a WMT_BUFFERING_START message, but not sent the corresponding WMT_BUFFERING_STOP. There is, however, no guarantee of how quickly the reader responds to the request. This feature is particularly useful when the play mode is set to WMT_PLAY_MODE_DOWNLOAD.
