I think I've nailed it down. % ls -l 01-Aria-Andreas\ Almqvist.flac -rw-rw-r-- 1 julien julien 8782782 Jun 22 17:43 ../01-Aria-Andreas Almqvist.flac Looking at the file, there's a lot of metadata in there, including album art and an Apple XML plist among others. It looks like that takes some room, let's see. % metaflac --remove-all --dont-use-padding 01-Aria-Andreas\ Almqvist.flac ( /!\ this removes all metadata so don't do that on the original file /!\) % ls -l 01-Aria-Andreas\ Almqvist.flac -rw-rw-r-- 1 julien julien 8705051 Jun 22 18:07 01-Aria-Andreas Almqvist.flac So the file is 77731 bytes smaller with all metadata stripped, which is 75.909 kB. And indeed: % metaflac --list 01-Aria-Andreas\ Almqvist.flac | grep " length:" length: 34 length: 234 length: 908 length: 71445 <=== jpeg album art length: 5128 Now, there was a bug in ffmpeg with FLAC files with more than 64 kB of metadata (ffmpeg issue 187), and it's quite possible our version of ffmpeg in stable is affected by that (I note that your version of libavcodec & friends is different from the one I have on my Lenny machine, by the way). If you have other files from the same origin, you might want to check the metaflac output to see if any of the files are similar in this aspect; I expect all files should be below 64k. Anyway, that's an ffmpeg bug, and if it's the 64k bug, I think it can be fixed with the upstream patch pretty easily.
