- Modify ProcessDecodedData to return a MediaResult. - RemoteDecoderParent::RecvInput and RemoteDecoderParent::RecvDrain both use error returned from ProcessDecodedData to call SendError. - RemoteVideoDecoderParent and RemoteAudioDecoderParent both return MediaResult with NS_ERROR_OUT_OF_MEMORY if AllocShmem fails in ProcessDecodedData (or if the returned buffer size is less than the requested size).
