Syntax

C++


HRESULT GetStreamAttributes(
  [in]  DWORD         dwStreamIdentifier,
  [out] IMFAttributes **ppAttributes
);

Parameters

dwStreamIdentifier [in]: The identifier of the stream. To get the identifier, call IMFStreamDescriptor::GetStreamIdentifier on the stream descriptor.
ppAttributes [out]: Receives a pointer to the IMFAttributes interface. The caller must release the interface.

Return value

This method can return one of these values.

Return code	Description
S_OK	Success.
E_NOTIMPL	The media source does not support stream-level attributes.
