Return value

Internally, the source reader calls the IMFSourceResolver::CreateObjectFromByteStream method to create a media source from the byte stream. Therefore, a byte-stream handler must be registered for the byte stream. For more information about byte-stream handlers, see Scheme Handlers and Byte-Stream Handlers.
