[Mp4-tech] H.264 Queries

[Gary Sullivan]

You may also need to consider buffering period SEI messages.  I think that would be everything -- just VUI, PT SEI, and BP SEI.

Subject: [Mp4-tech] H.264 Queries
Hi,
I am trying to generate a fast forward file using a normal H.264 file. I
am doing the following steps:
1. Pick IDR pictures at an interval such a way that playing those IDR
pics gives the required fast forward feeling.
2. Make sure that for these selected picturesHRD analysis is OK.
My question is, what all RBSP syntax elements change due to above process.
As far as I think, we have to change the following:
1. Sequence Parameter sets to reflect new values of HRD parameters
2. Timing SEI messages.
My understanding is also that Nothing in the picture parameter sets,
picture/slice data needs to be changed.
Please let me know if my understanding is correct.
thanks
Prashant
