[gentoo-user] OT: encoding MP3 files for iPod
Greetings; I have acquired an iPodNano and have been playing about with that. I've been able to do everything I need to do using GNUpod, yet there is an oddity. Any MP3 file I encode on my computer will not play. The file is there, the iPod sees it, but when I try to play the song, it simply skips over it. I don't have this problem with MP3 files from other sources. My first guess is that something is different in the encoding process? A few hours of reading man pages and Googling haven't helped any. Suggestions?

Most likely problems are (1) bitrate (2) CBR vs. VBR and (3) metadata location. I don't know exact specs, but the same thing will happen on my iFP-799 if I use a bitrate that is either too high or too low. My iFP also supports VBR, but some devices may not. If you know you are using a bitrate that is supported by your nano, try stripping off all the ID3 tags (and any other metadata), it could be that the contents or location are confusing it. I've fairly sure metadata can be stored either at the beginning or end of the file (I know FLAC can do this) and it's possible, albeit unlikely, that the nano only works with one of those locations. -- If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability. -- Gentoo Developer Ciaran McCreesh pgp7nIRY1lwOw.pgp Description: PGP signature

quoth the Boyd Stephen Smith Jr.: I've fairly sure metadata can be stored either at the beginning or end of the file (I know FLAC can do this) and it's possible, albeit unlikely, that the nano only works with one of those locations. MP3 Id3v1 tags are at the end, ID3v2 tags are near the begining. Some files have both. As for Flac, this is not true. As one who recently wrote a Ruby library for parsing Flac metadata (and thus read the Flac spec[1]) I can say that all metadata, including the VORBIS_COMMENT block are before the stream contents (ie: the audio bits). The various metadata blocks can be in arbitrary order but always before the actual music data.

As for Flac, this is not true. My mistake; the specification is quite clear that metadata can only appear before audio data. I must have been thinking of Ogg/FLAC or something else. -- If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability. -- Gentoo Developer Ciaran McCreesh pgp3wW2fw6VRZ.pgp Description: PGP signature
Re: [gentoo-user] OT: encoding MP3 files for iPod
Thanks to you both. Wanna here something strange. . . or maybe not. It's the file name. A file named Pink Floyd - Dark Side of the Moon - 02 - On The Run.mp3 will not work. I rename it to pf-dsotm-03.mp3 and it works just fine. I don't know why yet. I have mp3 files which have come from the internet which have spaces, capital letters, lower case letters, numbers, and they work fine. When I have time my curiosity will force me to experiment some more to find out exactly what causes this, but for now I'm content to be loading the thingy up with music.
