New Music Tag Reader -- Testers needed (1 Viewer)

[zombiepig]

Steve - new version works perfectly on all genres
i let it loose on my main music share (about 6000 flac+mp3 files), and it scanned all without issue in about 3 minutes. i realize it's not adding to the database or anything but this is SUCH an improvement over the ~40 minutes it takes to scan the same share in mp atm!!

hi Steve,

Good work on the new tag importer, i love it
Just a suggestion when you start integrating it in MP
Instead of use the current music database, maybe its time
to completely redesign the music database?
The new tvserver engine will use a sql database running on for example sql server express to store all tv related data in.
Perhaps its a good idea to use the same thing for music ???
if you like it, take a look at IdeaBlade DevForeExpress
Its an object/relational mapper framework for databases which
I currently use in the new tvserver.
Its a free download http://www.ideablade.com/downloads.html

This http://en.wikipedia.org/wiki/Object-relational_mapping
nicely explains what an o/r mapper does and why it would be wise to use it if you ever design a new database

The nice thing with IdeaBlade is that it can generate C# classes by analysing the database tables and foreign keys. No need to write any dataaccess code anymore which speeds up development tremendously

- Do you plan to read additional tags from the files - the one I am missing the most is the composer tag, which is crucial for ordering classical music.

The tag reader currently reads the composer frame so it is there--I just don't show it in the test app.

- Do you plan to support more than one artist by song - e.g. "Ray Charles, Norah Jones" so that they appear as two separate songs in the database?

Thx a lot

If the file's tagging format supports multiple artist frames than it should be possible to read all the artist frames. Do you have any files tagged as such?

Moving to SQL2005 Express is something I've been thinking about for while and I think it would make a lot of sense to have the changeover coincide with the new tag reader. I had a look at DevForce when you first mentioned it in your tvserver engine post several weeks back and have been playing around with the turorials--pretty slick!

Version 0.22 has been released (see first post for link)

Changes:

Add logging
Fix problem reading embedded coverart in MP3 files
Fix problem in Ogg files when reading comments without "=" delimiter that was causing erroneous OutOfMemory exceptions
Fix problem in Ogg files when reading Year comment that included month and day values (2001:12:6)

TODO:

WMA problems still need to be fixed

Hi steve, running latest version now, ogg pros seems to be working now.

On question: would it be possible to include a human-readable interface for the database? It probably should be low-pri but if it is easy to implement. I mean sometying like .xml export/import so that the user may read the db info in an xml file, do search and replace manually, debug tagging etc, then import that info back into the usual high-performance database.

AFAIK the ID3v2 standard does not support multiple artists. But - from memory - WMP 10 presented multiple artist files correctly under each artist whenever they were separated with a column, e.g. "Ray Charles; Norah Jones".

Done! Retrieved 17241 tags in 00:08:19,44 (0,029 secods pr track)

I scimmed the log. Common:
MP3Tag.get_Year caused an exception: Input string was not in a correct format.

WmaTag.Read caused an exception: Unable to load DLL 'WMVCore2.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
TagReader.ReadTag returned false for: C:\musikk\filename.wma

15.07.2006 18:41:29 MP3Tag.get_CoverArtImageBytes caused an exception: Arithmetic operation resulted in an overflow.

Can you send a a couple of files that include multiple artists delimited with semi-colons? I'll PM you my address.

Thanks
