Hi all, OK, so I just bought myself a nice shiny new powerbook. Nice machine. Very nice machine :-) But, iTunes does not understand FLAC. My Digitised music collection (entirely my own, ripped from my cd's, blah, blah, blah) is now mostly in FLAC (as I slowly go through and convert it will all be in FLAC :-) So, I have a problem. Or, if you want to look at it another way, I have an itch. An itch that I intend to scratch. Looking around, I have seen that a similar itch was scratched (http://qtcomponents.sourceforge.net/) but this project seems to be dead. Does anyone here know what is/has happen(ing|ed) (with|to) it? If I set about writing the quicktime component to play FLAC (and OGG/SPEEX) is anyone here interested in merging it into the mainstream? Does anyone here know anything that I should be particularly wary of when I start to approach this project? Are there any other questions that I should of asked, and do you have answers for them? :-) Thanks in advance, Paul --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

Quicktime support has been a huge weakness for us and we definitely welcome any help you can offer.> Does anyone here know anything that I should be particularly wary of > when I start to approach this project?I've not looked at the issues my self, but I can repeat some vicious rumours. Quicktime has had problems with vbr audio support in the past. This may be fixed now, but for a long time the mp3 support was a complete special-purpose hack. There also seems to be a problem with the way vorbis passes codec setup information at the start of the stream. I believe the current implementation uses a hack to get around this. A general ogg demuxer that works with multiplexed streams is an open question as far as I've heard. Apple has traditionally not offered us any help, even when someone donated a support issue on the topic. iTunes, against all policy if not al reason, doesn't use quicktime except for play fallback. Then encoder plugins use some unocumented api. Someone would need to reverse-engineer that for full xiph-codec support. Perhaps someone who actually knows something can follow up with real information :) Anyway, do keep us appraised of your investigations. We're very interested in this. And good luck. -r --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.
