Hi,
According to the spec 14496-1, if the value of
DecoderConfigDescriptor.objectTypeIndication refers to
streams complying ISO/IEEC 14496-2, the syntax and
sematics of decoder specific info are defined in Annex
K of the spec. 
My question is: in above case, does the syntax and
sematics of decoderSpecficInfo have to comply to Annex
K or what is defined in Annex K is just an option for
the content in decoder specific info descriptor?
According to Annex K, "VisualObjectSequence() is
transmitted explicitly in each
DecConfigDescr.DecSpecificInfo of an Object
Descriptor". Does this mean that the content should
follow what it is defined in 6.2.2 of 14496-2?
Thanks,
Chen
