The license of the MPEG-4 reference code is as follows, and I'd say that it's _not_ what we call "as-is": This software module was originally developed by Nokia in the course of development of the MPEG-2 AAC/MPEG-4 Audio standard ISO/IEC13818-7, 14496-1, 2 and 3. This software module is an implementation of a part of one or more MPEG-2 AAC/MPEG-4 Audio tools as specified by the MPEG-2 aac/MPEG-4 Audio standard. ISO/IEC gives users of the MPEG-2aac/MPEG-4 Audio standards free license to this software module or modifications thereof for use in hardware or software products claiming conformance to the MPEG-2 aac/MPEG-4 Audio standards. Those intending to use this software module in hardware or software products are advised that this use may infringe existing patents. The original developer of this software module, the subsequent editors and their companies, and ISO/IEC have no liability for use of this software module or modifications thereof in an implementation. Copyright is not released for non MPEG-2 aac/MPEG-4 Audio conforming products.
