Re: [SlimDevices: Plugins] MusicIP + tags

2010-09-20 Thread mikerob

Can the .m3lib file be editted if the file location changes?

A number of years ago I did experience some problems after archiving
MusicIP fingerprint data into tags (I think there was a bug at the time
that was subsequently fixed) so I've been reluctant to do this ever
since.

Re: [SlimDevices: Plugins] MusicIP + tags

I use IDv2.3 for mp3 in my library. I also use genpuid to scan music and
store the MusicIP data in the tags.  This has the advantage that all
that analysis time is stored in the file and that to reinstall musicip,
or whatever, the rescan is quick.

I frequently take a backup of *.m3lib and *.m3usr, which can be restored 
following a reinstall, so no rescan would be necessary.

A MusicIP re-analysis would only be needed if music files change location.

But if the files contain the tags the reanalysis would be very quick.

Yes it does, but just tags not the music itself. It writes an Analysis
and Fingerprint that it uses for mixing, as shown in the attachment.

 The reason I ask is that I think I've read a post somewhere someone
 complains that MusicIP has buggered up the tags on their music
 collection...

It's harmless IME, and can be removed at any time.

 Also Squeezebox seems to have two settings for MusicIP :
 
 Only read mixable status from MusicIP (faster)
 Import all song data from MusicIP (slower)
 
 Is the second one worth bothering with?

Dunno, I have always stuck with the first option. :)

Further thought: there is a fix tags option with MIP. I suspect this
might have the capacity to work mischief and have always avoided it.
I'm sure someone here will know exactly what this button does,
though...

Ah ok, so it doesn't overwrite existing tags, it has its own little
area and sticks to that?

Yeah if that's all it does then that's fine. =)

Re: [SlimDevices: Plugins] MusicIP + tags

2010-09-13 Thread Phil Meyer
Quick question - does MusicIP alter files?

Only if you tell it to.

There is an option to write fingerprint and analysis data tags.  This was 
advertised as harmless - adding extra tags that wouldn't replace any existing 
tags in the music files.  However, I found that the process of adding MusicIP 
tags to id3v2.3 tags that have multiple values, eg. two artist tags, two genre 
tags, etc, would lose all but the first value.

e.g., using Mp3tag, you can add two genres by setting the value to Rock\\Pop 
(equivalent to entering GENRE=Rock, GENRE=Pop).  If I archive MusicIP analysis 
to the music file, it would lose the second genre, leaving only GENRE=Rock.

This may be due to the id3 standard for id3v2.2 / 2.3 tags, which doesn't 
officially allow multiple values (2.4 does officially).  I think it stores a 
single GENRE tag with values separated with a NULL (0), which Mp3tag represents 
with separater \\.

I don't think MusicIP writes v2.4 tags; it will change an mp3 file to v2.3.

There may be other issues - I decided not to perform archive analysis, and take 
the hit of needing to re-process files if they move.  I backup my musicIP data 
file frequently.

I think there are also actions to fill in missing tags, etc.


You can use MusicIP without it modifying music files, which is what I'd 
recommend.

Only read mixable status from MusicIP (faster)
Import all song data from MusicIP (slower)

Is the second one worth bothering with?

No!  I think there is no reason to ever use MusicIP import.  You are much 
better off with only reading mixable status, for various reasons:

1. It's a lot faster.
2. MusicIP supports less formats than SBS.  i.e. SBS can scan files, and adds 
mixable status if the song is detected by MusicIP.  If it isn't in MusicIP, it 
is still playable in SBS, just not mixable.
3. MusicIP does some weird stuff with missing tags, which can be very annoying. 
 eg. SBS will fill in missing album tags with Miscellaneous, so if you rip 
lots of singles they will appear in SBS as either a single compilation album 
called Miscellaneous or several albums (one per artist).  SBS handles this a 
lot nicer.

If you do decide to use MusicIP import, I think it's a good idea to clear the 
SBS music library path, so that it never tries to merge SBS scanned files with 
MusicIP scanned files.

I don't know how MusicIP import will work with SBS 7.6 new scan features.  eg. 
Auto rescanning on new/changed files detection.  You might find it does a whole 
import every time it sees a change.

That makes sense, I've just done some testing and no changes were made
to any flacs or mp3s.

Philip Meyer;576324 Wrote:

I'm guessing I'm missing an admin interface then, currently running
MusicIP on a headless Lunix server and admining via the provided web
interface.

That's a shame, it implies MusicIP doesn't honour multiple genre tags
when creating its playlists.

Aye this appears to be the default and how it's currently scanning, it
doesn't have permission to make changes anyway so I guess this has
answered my question that it will perform normally without writing
metadata to the mp3 files.

Cheers all.

Indeed, it doesn't.  It's another reason why it's best to scan with SBS and 
only get mixable status rather than import metada.  You would also lose other 
SBS scanning capabilities, such as more control over artwork, composers, 
conductors, band/orchestra, compilation/album artists, etc.

genpuid hasn't done any damage to the tags in my mp3s or flacs so quite
happy with it.

MusicIP's import is not worth it.  Only use scan for mixable status. 
MusicIP's fix tag option is probably also not as good as other options.
