This section documents the ObjectTypeIndication used in MPEG-4 systems to indicate the type of streams. Applications for a new codec type will also automatically receive an object type indication.

This table also occurs in ISO/IEC 14496-1 (various versions), the MPEG-4 systems specification. The intent is that the table maintained by this registration authority is the most up-to-date and definitive version.

There is also an informative table of the current StreamType allocations.

0xFF no object type specified (e) MPEG-4
  1. This type is used for all 14496-1 streams unless specifically indicated to the contrary. Scene Description scenes, which are identified with StreamType=0x03 (see Table 9 ), using this object type value shall use the BIFSConfig specified in section 9.3.5.2.2  of this specification.
  2. Used, with StreamType=0x03 (see Table 9 ), for Scene Description streams that use the BIFSv2Config. Its use with other StreamTypes is reserved .
  3. Includes associated Amendment(s) and Corrigendum(a). The actual object types are defined in ISO/IEC 14496-2 and are conveyed in the DecoderSpecificInfo as specified in ISO/IEC 14496-2, Annex K.
  4. Includes associated Amendment(s) and Corrigendum(a). The actual object types are defined in ISO/IEC 14496-3 and are conveyed in the DecoderSpecificInfo as specified in ISO/IEC 14496-3 subpart 1 subclause 6.2.1.
  5. Streams with this value with a StreamType indicating a systems stream (values 1,2,3, 6, 7, 8, 9) shall be treated as if the ObjectTypeIndication had been set to 0x01.
  6. For PNG Streams, the following configuration/rules apply:
  7. Includes associated Amendment(s) and Corrigendum(a). The actual object types are defined in ITU-T Recommendation H.264 | ISO/IEC 14496-10 and are conveyed in the DecoderSpecificInfo.
  8. Used,  with StreamType=0x03, for Scene Description streams that use the BIFSConfigEx; its use with other StreamTypes is reserved. (Was previously reserved for MUCommandStream but not used for that purpose.)
  9. Used,  with StreamType=0x03, for Scene Description streams that use the AFXConfig; its use with other StreamTypes is reserved.
