Nano 5g support.

Rate this Message:
G'day guys,
I've just picked myself up a nice shiny new Nano 5g ( http://en.wikipedia.org/wiki/IPod_Nano#Fifth_generation ). I was very disapointed to see that it appears Apple has changed the DB format. When I connect to rhythmbox for example (which uses libgpod for iPod syncing), it happily syncs my music to the iPod. This music can also be read by other music players using libgpod, but the iPod itself fails to notice them. Has anyone else had any experience with these? I had a peak around the contents once I synced from iTunes on a Windows VM, and the news looks good. The data for playlists/artists/songs/etc is stored in an sqlite3 database! What I would like to do is work on a feature which will connect to the Sqlite DB instead of the crazy itunesdb file if a newer iPod is specified, so that libgpod can access the new Nano's. Does this sound like something which could be done? I reckon there will be much less reverse engineering required, because it is quite easy to have a browse around the sqlite databases and see what DDL they used to create the tables, and look at what type of values are stored in them. If anyone wants the database files, I'm happy to upload them somewhere. Any thoughts? cheers, Pete. ------------------------------------------------------------------------------ Come build with us!

I have the new Ipod 7g (160gb) and am getting the exact same results. Everything happily syncs with libgpod but Ipod doesn't recognise that the Ipod has songs on it. Hooking back into Itunes, it requires a restore?

Ah ok, because I found this tweet which sounds very promising: http://twitter.com/isrark/status/3164553506 If only we could get him to elaborate... A few of his followers have asked, and there has not yet been a response. If it turns out that it isn't possible to get more info on it, I'm quite happy to contribute in any way possible to trying to figure out how to sign the database (I've been looking for an open source project to sink my teeth into recently) > I already tried to remove the sqlite files altogether and it > seems the ipod needs them.

Looks like it: pete@satan:/media/IPOD$ find iPod_Control iPod_Control iPod_Control/iTunes iPod_Control/iTunes/Play Counts iPod_Control/iTunes/iTunes Library.itlp iPod_Control/iTunes/iTunes Library.itlp/Genius.itdb iPod_Control/iTunes/iTunes Library.itlp/Dynamic.itdb iPod_Control/iTunes/iTunes Library.itlp/Extras.itdb iPod_Control/iTunes/iTunes Library.itlp/Library.itdb iPod_Control/iTunes/iTunes Library.itlp/Locations.itdb iPod_Control/iTunes/iTunes Library.itlp/Locations.itdb.cbk iPod_Control/iTunes/iTunesSD iPod_Control/iTunes/iTunesPlaylists iPod_Control/iTunes/ShowLicense iPod_Control/iTunes/iTunesControl iPod_Control/iTunes/ShowRegistration iPod_Control/iTunes/iTunesDB iPod_Control/iTunes/iTunesCDB iPod_Control/iTunes/iTunesPrefs iPod_Control/iTunes/iTunesPrefs.plist iPod_Control/iTunes/Rentals.plist ... All the .itdb files are sqlite files. And here is the iTunes folder file sizes (note iTunesDB size is zero). So is that iTunesCDB just all of the sqlite databases compressed this time around then? pete@satan:/media/IPOD$ ll iPod_Control/iTunes/ total 21M drwx------ 3 pete root 16K 2009-09-25 21:38 . drwx------ 11 pete root 16K 2009-09-22 19:09 .. -rwx------ 1 pete root 28K 2009-09-23 22:47 iTunesCDB -rwx------ 1 pete root 20M 2009-09-22 21:35 iTunesControl -rwx------ 1 pete root 0 2009-09-23 22:47 iTunesDB drwx------ 2 pete root 16K 2009-09-25 22:20 iTunes Library.itlp -rwx------ 1 pete root 8 2009-09-22 19:13 iTunesPlaylists -rwx------ 1 pete root 1.3K 2009-09-23 22:47 iTunesPrefs -rwx------ 1 pete root 2.8K 2009-09-23 22:47 iTunesPrefs.plist -rwx------ 1 pete root 23K 2009-09-22 19:19 iTunesSD -rwx------ 1 pete root 3.4K 2009-09-25 21:36 Play Counts -rwx------ 1 pete root 245 2009-09-23 22:47 Rentals.plist -rwx------ 1 pete root 0 2009-09-22 21:35 ShowLicense -rwx------ 1 pete root 1 2009-09-23 22:37 ShowRegistration > I was sent these patches for the iphone os 3.0 > http://cgit.freedesktop.org/~teuf/libgpod/log/?h=iphone30 which I suck > at integrating in mainline :-/ I suspect most of the code can be > reused for the nano5g. > > Hope that helps, > > Christophe Cheers, Pete ------------------------------------------------------------------------------ Come build with us!

I will definitely check this out (no pun intended). I've been looking for an excuse to play around with git also, as a bzr user. I'll grab that branch and have a read through the docs and code when I get a chance and see if I can get it at least reading from my nano. cheers, Pete. ------------------------------------------------------------------------------ Come build with us!

I presume it also writes back to the iTunesCDB correctly, but I'm unsure as to whether the iPod interface reads from the sqlite databases or the itunesDB file... Naturally, the only problem is the .cbk file. Using the ideas from this mammoth thread: http://www.hydrogenaudio.org/forums/index.php?showtopic=45160&st=2100&p=644564#entry644564 (gets interesting/relevant around page 85->90), where they open up their iPod in iTunes and then do something which will cause iTunes to modify any data on the device. This will recreate a new .cbk file based on the databases which are there. So databases created successfully on linux, and then the .cbk file created by iTunes. At least I think/hope that is what is happening, I will try again tomorrow and check the timestamps of each file after gtkpod and itunes interaction to see who is touching what. Obviously this isn't a long term solution, but just wanted to let you know that those patches you integrated for iphone 3.0 seem to be working for the nano5g as suspected. cheers, Pete. ------------------------------------------------------------------------------ Come build with us!

Or did it do that out of the box? I'd say the ipod > interface uses the sqlite files, but that's just a guess. > No changes to gtkpod, only compiling against your iphone3.0 git branch for libgpod. Anyway, in the cold light of day (when I'm actually a little bit awake), I would like to withdraw half of my statements. This is my interpretation of events: gtkpod *reads* successfully (from the iTunesCDB file) gtkpod *writes* successfully to the Library.itdb (and whatever other databases are required): - if I run a select on the items table in the Library.itdb file, it returns the correct list of songs. gtkpod *doesn't* write successfully to the iTunesCDB file: - when I open gtkpod again, the songs I removed are still there - although the sqlite database is still correct. If I open iTunes, it will rewrite out the sqlite databases, I imagine based on the contents of the iTunesCDB file. So yeah, not as I'd hoped. I guess I'll be hanging around until the hashing scheme is discovered. cheers, Pete ------------------------------------------------------------------------------ Come build with us!
