great, thanks :-) So the last remaining tool to check is oggz-chop. I at first assumed it would not work with Dirac's granulepos, but it seems to do something vaguely useful: [EMAIL PROTECTED]:~/share/oggz-chop$ oggz chop -s 7 -e 11 -o sage-7-11.ogv ../dirac/sage-640x360.ogg [EMAIL PROTECTED]:~/share/oggz-chop$ oggz dump sage-7-11.ogv |grep serialno | head -n 20 00:00:00.000: serialno 1762443388, granulepos 0, packetno 0 *** bos: 64 bytes 00:00:00.000: serialno 1763535876, granulepos (pt:0,dt:0,dist:0,delay:0), packetno 0 *** bos: 39 bytes 00:00:00.000: serialno 0719746932, granulepos 0, packetno 0 *** bos: 30 bytes 00:00:00.000: serialno 0719746932, calc. gpos 0, packetno 1: 75 bytes 00:00:00.000: serialno 0719746932, granulepos 0, packetno 2: 3.742 kB 00:00:00.000: serialno 1762443388, granulepos 0, packetno 1: 80 bytes 00:00:00.000: serialno 1762443388, granulepos 0, packetno 2: 81 bytes 00:00:00.000: serialno 1762443388, granulepos 0, packetno 3 *** eos: 0 bytes 00:00:06.923: serialno 1763535876, granulepos (pt:334,dt:332,dist:51,delay:2), packetno 2: 1.685 kB 00:00:06.965: serialno 1763535876, granulepos (pt:344,dt:334,dist:52,delay:10), packetno 3: 16.928 kB 00:00:07.007: serialno 1763535876, granulepos (pt:338,dt:336,dist:53,delay:2), packetno 4: 1.529 kB 00:00:07.048: serialno 1763535876, granulepos (pt:340,dt:338,dist:54,delay:2), packetno 5: 1.761 kB 00:00:07.090: serialno 1763535876, granulepos (pt:342,dt:340,dist:55,delay:2), packetno 6: 1.576 kB 00:00:06.857: serialno 0719746932, calc. gpos 329152, packetno 4: 1 byte 00:00:06.878: serialno 0719746932, calc. gpos 330176, packetno 5: 1 byte 00:00:06.900: serialno 0719746932, calc. gpos 331200, packetno 6: 1 byte 00:00:06.921: serialno 0719746932, calc. gpos 332224, packetno 7: 1 byte 00:00:06.942: serialno 0719746932, calc. gpos 333248, packetno 8: 1 byte 00:00:06.954: serialno 0719746932, calc. gpos 333824, packetno 9: 1 byte 00:00:06.957: serialno 0719746932, calc. gpos 333952, packetno 10: 45 bytes However I don't know if this output is correct. What it is supposed to do is create a file containing all packets for display between 7 and 11 seconds, and to include all packets required to decode those, ie. all reference frames that are required by packets from 7s onwards. The original file included two more Dirac packets immediately prior to those included in the chopped output, but I don't know how to tell if these are required reference frames for those from 7s (or from 6.965s) onwards: [EMAIL PROTECTED]:~/share/oggz-chop$ oggz dump ../dirac/sage-640x360.ogg |grep serialno ... 00:00:06.814: serialno 0719746932, calc. gpos 327104, packetno 406: 1 byte 00:00:06.836: serialno 0719746932, granulepos 328128, packetno 407: 1 byte 00:00:06.840: serialno 1763535876, granulepos (pt:330,dt:328,dist:49,delay:2), packetno 168: 1.603 kB 00:00:06.881: serialno 1763535876, granulepos (pt:332,dt:330,dist:50,delay:2), packetno 169: 1.683 kB 00:00:06.923: serialno 1763535876, granulepos (pt:334,dt:332,dist:51,delay:2), packetno 170: 1.685 kB 00:00:06.965: serialno 1763535876, granulepos (pt:344,dt:334,dist:52,delay:10), packetno 171: 16.928 kB 00:00:07.007: serialno 1763535876, granulepos (pt:338,dt:336,dist:53,delay:2), packetno 172: 1.529 kB 00:00:07.048: serialno 1763535876, granulepos (pt:340,dt:338,dist:54,delay:2), packetno 173: 1.761 kB 00:00:07.090: serialno 1763535876, granulepos (pt:342,dt:340,dist:55,delay:2), packetno 174: 1.576 kB 00:00:06.857: serialno 0719746932, calc. gpos 329152, packetno 408: 1 byte 00:00:06.878: serialno 0719746932, calc. gpos 330176, packetno 409: 1 byte ... So: - is the current output correct? - if not, how should the packets that a given packet depends on be determined, ie. how to determine reference frames? Is it possible to do so using only the granulepos encoding?
