[Mp4-tech] H.264 DPB storage

[EricChuang via.com.tw]

Hi Experts,
I have two questions regarding the DPB storage.
1. The standard specifiy the method to decide the maximum DPB slot count
in Annex A, depending on the level value. Does this level means decoder
level or bitstream level ?
2. In Annex C, the DPB operation described is used for both reference
picture and non-reference picture, is this an enforcement ? If I let DPB
storing reference picture only, and create another mechanism for
managing non-reference picture, and handle the reoder and
no_output_of_prior_pics_flag, would this cause any decoder conformance
problem ?
Thanks very much for your answering in advance,
Eric
