IAMTimelineGroup::GetSmartRecompressFormat

The GetSmartRecompressFormat method retrieves the current compression format for smart recompression .

Syntax

  HRESULT GetSmartRecompressFormat(
   long **ppFormat
);

Parameters

ppFormat

Address of a variable that 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

Returns an HRESULT value. Possible values include the following.

Return code Description
S_OK Success.
E_OUTOFMEMORY Insufficient memory.
E_POINTER NULL pointer argument.

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;
}
