Ogg FLAC is simply FLAC files stored in Ogg containers. I don't know if there are any advantages with it since normal FLAC already handles Vorbis comments, ReplayGain, cue sheets and more...

Ogg container is an excelent container for streaming of files in real time, if anybody liked to do so with lossless audio files, say over a LAN for a high quality network internal radio .... Ogg is also very error resilient, so in principal it could be well possible that an old CD containing Ogg FLACs can be played, while the normal FLAC can not ( i have to admit i dont know much about FLAC framing as of yet ).

Another thing thats pretty common to do in the video compression scene is to burn the CDs in mode2 form 2 , offering 800 MB on a normal 80 mins CD. Of course, error resistance is much worde then as one complete layer of ECC is missing on the CDs, but with some intelligent method you could easily protect the main headers of the container with say 20 MB, leaving you with 780 MB to use for data and the file will play in any case, even from a scratched CD. The XCD Team has this plans ( http://xcd.sf.net ) and does support Ogg already.

Last thing was to use FLAC for movies together with Theora in Ogg. The VirtualdubMod people plan to look at FLAC for lossless real time capturing from analog sources, in either OGG ( OGM ) or matroska container ....

I need to warn you, though, that currently OggFlac does NOT support seeking and metadata storage and can not be played in winamp.

also, native FLAC format is good enough for what it needs to be.

What makes the Ogg-container more resistent to errors?

I've read the XCD guide about storing 800MB ogm files on a 700MB CDR. The size of an Ogm with the same video file as an Avi does not differ much. I made some ogms and the divx + ogg ogm-file was 600KB (hope I remember this correctly) bigger than was the single avi + the single ogg file. This additional data has the same effect as the 100MB of the normal burning of a regular data CD?
I love the moderators.

fragtal, make your XCDs with DVX so you can understand the difference...

thx!!

Actually I use xmpeg which offers me all functions I need for (nearly ) flawless Xvid DVD-rips. I don't like changing programs I am used to all the time . but I'll try DVX
