This is the related part in the spec ISO/IEC 14496-1:
8.6.6.2 Semantics
The DecoderConfigDescriptor provides information about the decoder type and the
required decoder
resources needed for the associated elementary stream. This is needed at the
receiving terminal to determine
whether it is able to decode the elementary stream. A stream type identifies
the category of the stream while the
optional decoder specific information descriptor contains stream specific
information for the set up of the decoder in
a stream specific format that is opaque to this layer.
ObjectTypeIndication – an indication of the object or scene description type
that needs to be supported by
the decoder for this elementary stream as per Table 8. For streamType values
other than audioStream and
visualStream, the objectTypeIndication shall be set to 0xFF, indicating that no
object type is specified.
