Basically it just maps time stamps (PTS) to packet offsets in the file. It is used for seeking and angle changes. > What does CPI stand for? Characteristic Point Information > What's the EPMap? (and what does EP stand for?) EP = Entry Point ? EPMap contains (PTS,SPN) pairs for single stream. Points are guaranteed to fullfit some properties: video: sequence header + I frame or SPS + I / IDR frame audio: PES packet start PG/IG: PCS/IGS segment following with complete display set i.e. those are points where it is possible to start decoding. There are also flags for for possible angle change points. > What does SPN stand for? (I guess something like Stream Packet Number) Yes, Source Packet Number. - Petri _______________________________________________ libbluray-devel mailing list [email protected] http://mailman.videolan.org/listinfo/libbluray-devel
