[Mp4-tech] H.264 Buffer analysis

[yashwinder chhikara]

Hi,In H.264, for doing the CPB buffer analysis,We require the VUI information, the buffering period and picture timing SEI messages to be present in the stream.If this information is present then we can do the required CPB buffer analysis as given in the specs.. Now if this information is not present in the stream ( which is the casefor approx. 95% of the test streams available), can there be any othermanner we can do the CPB buffer analysis using the coded information.Any ideas are welcome...RegardsYashwinderSriram Sethuraman  wrote:Gary/Iain,We, Ittiam Systems (Pvt.)
