After looking at streaming stuff, I figure there's a small change that we need to make to the way headers are done. Headers should be page aligned. Ie, when the header ends, the current page in the ogg stream should end, so that vorbis packets start in a fresh page. This is necessary because i don't want to have to repaginate the entire stream because I have to cache a header to be

Monty, Thanks for writing up your thoughts on the mux design (ogg/doc/ogg-multiplex.html in cvs) Now that there's something to argue with, I'd like to comment. To recap, the documented proposal is that we make two categories of streams within the OggFile multiplexing library. Pages are sorted chronologically by the timestamp equivalent of their granulepos fields. Normal data like

dear list, i am trying to write a small program which reads an ogg file and writes it to another ogg file (and changes serial number, granulepos etc on the fly). reading the ogg file is ok (ogg_sync_pageout, ogg_stream_pagein, ogg_stream_packetout). but writing the file doesn't work - the granulepos and page structures don't match with the original file. here's what i am doing.

David Flynn has proposed a new Ogg Dirac mapping. The draft is here: http://davidf.woaf.net/dirac-mapping-ogg.pdf This is a much bigger break from other codecs than my draft (at http://wiki.xiph.org/index.php/OggDirac). We talked a bit about it on IRC today. Below is my summary; hopefully David can correct anything I got wrong or misleading. Comments? There are two main differences
