// The Splitter will stop the graph prior to this call, and it will return the graph to its previous state afterwards.
//
// When this function is called, the pin will already have the new media types set, so the usual functions to query the media types can be used.
// EnmuMediaTypes is OK (or any wrappers of this in the base classes), ConnectionMediaType is not OK, for obvious reasons.
//
// Following return values are supported:
// S_OK - The player took complete control over the rebuild, the splitter will do no further actions regarding the pin
// S_FALSE - The player may or may not have changed the pin, and the splitter is instructed to send a media type with the next packet.
// E_FAIL - The player failed, and the splitter should try to rebuild the pin
