CPU usage during database rewrite gets as high as 420,000 K


Clean install used the same high amount of CPU BUT it did seem to go quite faster.

Specs

Windows XP

Experiencing issues when using itunes to play files directly from my ipod touch 3g. When itunes plays the files stored on the itouch, it reads the tags embedded in the files and updates the itouch database, sometimes removing the coverart and re-mapped meta data.

Full details:

At home, I use foo_dop to convert my flac files to .m4a AAC files and transfer them to my ipod touch. For all albums, foo_dop pulls the folder.jpg's from my HD and adds them to the itouch database for the corresponding albums (none of my coverart is embedded into the tags). For complilation/multiple artist albums, foo_dop remaps the Artist (to %album artist%) and Title (to %track artist% - %title%) Metadata for me. When I use my ipod touch, everything is perfect - Artists and Titles show up as I want them to for normal albums and compilation/multi-artist albums. All albums also show up with the correct coverart.

However, at work I use a Macbook Pro laptop with Itunes installed. Sometimes I plug my itouch into the laptop and have Itunes play music files directly from my itouch. I do this because my laptop feeds a separate dac and amp to drive some audio technica cans.

When I plug the itouch into my laptop, Itunes pulls all the metadata stored in the itouch database and reports the remapped Artist and Title metadata correctly. When Itunes actually plays the files from the itouch, it proceeds to read the tag info embedded directly in the .m4a files. Therefore, the re-mapped Artist/Title metadata revert back to what is actually in the tags. The itouch then updates its database with the embedded tag info Itunes just pulled and removes the coverart associated with the album. Because of this, the Artist and Title metadata remappings and coverart are no longer available on the itouch.

Mind you that this error doesn't occur 100% of the time, but it definitely occurs enough to warrant a fix.

I think the best solution would be for foo_dop to also update the embedded file tags with the remapped fields and coverart when transferring music to an ipod. Are there plans for this on the horizon?

Doesn't sound like CPU usage....

But is that just for foobar2000? It is quite high then. How many tracks are on your iPod then? Maybe it is something paging file related.

Can you download Process Explorer, open foobar2000.exe properties, and go to the Performance Graph page. Just monitor what it says for private bytes whilst you do a rewrite, and tell me what it is before, during and after the rewrite.

Can you also check how large your iTunesDB is, it is at iPod_Control\iTunes on the device. If it is something like >100MB, can you send me a backup to the e-mail on my website.

Well it took less than +4 minutes, lol (which the rewrite has been known to take for me before).

I got problems scrobbling ipod 5g stuff (it's Vista, foobar 1.0, latest audioscrobbler and dop plugins - updated yesterday to ensure it's recent).
The problem is I am not seeing any plays scrobbled nor even sent to last.fm.
Before you sync, check if the "Play Counts" file is present at \iPod_Control\iTunes on the device. It should be removed after syncing.

Play Counts file existed and was removed when sync was done.

Sync failed (in Console) with "duplicate column..." message as usual.

Quote from: musicmusic on
If it is, and support is definitely enabled in foo_audioscrobbler: make a backup of iPod_Control\iTunes with the Play Counts file and e-mail it to the address on my website.

foo_audioscrobbler is set to scrobble from ipod. I backed up whole iTunes folder (except for music files) before the sync and after the sync was done and PM'ed you full rapidshare link to the archive.

Remapping genre with "$meta(genre,0)" is not writing only the first genre; i.e. "Rock; Pop" will show up as "Rock, Pop" instead of "Rock". Any ideas on how I can fix this?

Request/Howto send converted output through a masstagger script

When the iPod manager convert source to mpa I would like each title to be changed to:
$if(%discnumber%,%discnumber%.%tracknumber%.%title%,%tracknumber%.%title%)
and without effecting the original files (flac)

Thanks

Edit:
Ok I think I've answered my own question
Tools | iPod Manager | Database | Metadata | Title Mapping
Just put the above code in there and its seems to work

As we discovered the problem was the available physical memory running out; my fault for writing hashing code etc. that likes to copy lots of memory around  With a low amount of RAM, and a quite large database, it became a problem here.

Such code has been rewritten in 0.6.6.6 into something saner.

Works here. If the tracks are already on the device, you'll need to use 'Update metadata' (see help button on the Prefs page). Otherwise double check the output in a playlist view column or similar.

Any tips on how to scrobble, when I don't normally sync my iPod with a playlist?

I finally got it to scrobble yesterday by beginning the sync process and then choosing no playlists.  Seemed a bit messy, and I wondered if I was missing an option that would automatically pull the info from the iPod.

I tend to just use "Send to iPod" to get music on there.

Perhaps I'm asking in the wrong place, and it is actually foo_audioscrobbler that is hooking in?  Thinking about the dialogues, this may be the case.

Edit:  OK, according to a post in the foo_audioscrobbler thread you have to Sync  or Rewrite the database.  I'd rather a dedicated menu item or something.

I never sync my iPod but I do scrobble it. Plug iPod, command "rewrite database", unplug iPod. I don´t see the point for a dedicated menu when you already have an option for that.

And I don't see the point in rewriting the database when I don't need to...

Guess that makes us different.

Perhaps a database rewrite is truly required, and I'd be happy with that, but it just sounds to me like overkill, to read some data.  My understanding may be seriously wrong.

Edit: I should point out that I'm not going to cry over it.  The post in the audioscrobbler thread has basically answered my question, I just thought I may as well post my reaction to it, and then later to eradumvelhinho's opinion on my personal opinion.  If I have to rewrite the database: So. Be. It.

I'm pretty sure foo_dop has to remove any playback information that's stored on the iPod while syncing - otherwise the same tracks would get scrobbled again and again and again...
np: 4'33"

From what I have read at the top of this page, there is a "Play Counts" file, that is deleted after synchronisation.  Not sure if this is related to the whole track database.

Again, my understanding is, no doubt, seriously flawed.

Hi everybody

I am currently a new user to Foobar2000 and its iPod manager. I've managed to view the music on my iPod nano 5th so far (iPod view). However, when I try to sync my Default playlist and my iPod view, it gives me an error saying "Failed to query device properties. Write operations are disabled."

Since syncing works fine in iTunes, I'm assuming this is a problem with Foobar2000?

Thanks.

Windows XP limited user maybe?

It will need admin rights on XP.

(Doesn't apply to Windows Vista and newer; iTunes uses a service).

Then it's probably a driver issue, try uninstalling Apple Mobile Device Support and reinstalling it (extract from iTunes installer). That should reinstall the driver.

Hello. I just recently made the switch to Foobar2000. Over the past several days I have been slowly rebuilding my music library thanks to iTunes screwing me over for the last time. I was told that Foobar would have no issue syncing with an iPod or iPhone device as long as I had downloaded and installed the appropriate components, which I have. Now I plugged in my iPhone and am trying to sync my new music library but Foobar is saying there is: "No iPod found". Am I doing something wrong? Please help.

Did you check "Enable mobile devices support" in the iPod Manager preferences? If you get stuck, have a read of the documentation, especially the FAQ.

Load Library command, select all tracks right-click ipod>update metadata should fix it up.

Sorry for being such a noob but do I just have to reinstall iTunes? I don't know how to extract *.exe files.

edit: I managed to install the Device Support but I keep getting the same error >_<

Hi,

If that happens again, have a look in Shift + File/iPod/Syslog viewer. Should be some indication there of what went wrong (the device does some processing on its side, such as sorting, and something probably went wrong there).

OK, try Shift + File/iPod/Raw properties and PM me the output.

ok, not too happy right now with foobar. any reason why foobar would just all of a sudden not open. i mean it opens, but nothing is displayed and it says "foobar is not responding".. can i uninstall and reinstall without my music and settings?
