[Mp4-tech] some doubts in H.264

[Thammi_Reddy]

Hi all,
Please answer to following questions related to H.264.
1.	What is the significance of picture order count and what are its
values for baseline profile?
2.	How often 'seq_parameter_set_id' changes. Why the upper limit of 31?
3.	Suppose we need a particular type of intra prediction, say
horizontal, Is it possible to get the encoded bit stream?
4.	What is the use of frame cropping, gaps in frames, P_skip, B_skip?
5.	How to choose which of the stored reference pictures to use for
prediction? Does this information come from encoder? The processing is more
if the decision to be taken by the decoder. Please comment.
6.	Intra/Inter decision also taken by the encoder?
