Support for MusicBrainz tags?

[tracycollins]

Hi,

Just started playing with this module. It works great. Thanks!

I'd love to be able to read any MusicBrainz tags on files, but it's not supported yet, right?

Any idea how difficult this would be to add? I'd try to do it myself, but I'm definitely a novice in JS and music metadata. Any help or pointers appreciated.

Hey Tracy,

It is not supported indeed. To be honest, I was not familiar with MusicBrainz until you brought this issue up. From a quick read up on their site it looks like they have a music database similar to IMDB but for music. With reading MusicBrainz tags do you mean these tags that I found on this page? https://picard.musicbrainz.org/docs/mappings/ They mention that they map some of the tags to ID3 TXXX type of tags.

Can you give me an example of a file that you want to read these tags from? From a technical point of view no worries, I'm more than happy to help here.

Hi, I'm looking for the same functionality. Yes, like those mentioned in the mappings table you linked to, specifically ones that start "musicbrainz_". These are mapped to the ID3 tags TXXX as shown in the table. Here is an example file: https://drive.google.com/open?id=0B6RwcFPH1EAXN3UwYUxuNnE3Ums . When I read the file with jsmediatags I see many entries under TXXX, but they are all [Object] and I can't see what's inside. I guess even without specific MusicBrainz support, I'd like to ask how can I view the TXXX tags? Thank you, and awesome project btw!

You need to look at the data inside that object, [Object] is what you see if you just print the object. User defined tags in TXXX have the format {description, data: {user_description, data} so you need to read those. I created a simple script that did this for the file you mention at https://jsfiddle.net/jt2bfkdj/, and here's the output:

Great, thanks for that, makes sense. My only question is why the data in the TXXX tags appears to be misformatted. E.g. when I look at the output of the tag "MusicBrainz Artist Id" using ffprobe, I get a long key string "804b1081-b5cd-4f13-baa3-b0ff46a86292" rather than the random characters above. Any idea why this would be? Thanks.

Hi!

Dear António Afonso, I'm really interested in this lib, to use in plain Javascript - can you please provide me with a straight example to use in such conditions?

All the best, Pedro Pimenta

@pedroccpimenta, you can see an example here: https://jsfiddle.net/3ef1cL58/

Thank You very much @aadsm ! Worked nicely with file loader button...

Last bothering :-) - instead, if we want to load a mp3 from the current directory, how could we do that?

All the best, PCP
