IAMTimelineGroup::GetSmartRecompressFormat method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Note
[Deprecated. This API may be removed from future releases of Windows.]
The GetSmartRecompressFormat method retrieves the current compression format for smart recompression.
Syntax
HRESULT GetSmartRecompressFormat(
long **ppFormat
);
Parameters
-
ppFormat
-
Receives a pointer to an SCompFmt0 structure, cast as a pointer to a long. If the method fails, the value is set to NULL.
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
If the application has not set a smart compression format (by calling IAMTimelineGroup::SetSmartRecompressFormat), the format returned by this method will be invalid. Call the IAMTimelineGroup::IsSmartRecompressFormatSet method to determine whether a compression format was set.
If the method succeeds, the caller must free the returned media type and delete the SCompFmt0 structure:
if (pFormat) {
FreeMediaType(pFormat->MediaType);
delete pFormat;
}
