Topic: M4a metadata

I did do a search for this, but nothing came up.  Maybe I am being dopey.

But anyway, every now and again Cog won't recognise ID3 tags even though they are there.  It's rare, but so far it has happened with M4A and MP3 files.  I've even taken the problem files into iTunes and re-written the tags but it doesn't help.  All it shows is the file names in the title column and the track lengths.

I'm running OSX 10.4.10 on an Intel MacBook, and Cog version 0.06 (r516).  Nothing out of the ordinary appears to happen in the console (although to be honest I don't even know what to look for anyway).

Re: M4a metadata

If you could send me a file that's having this problem I could look deeper into the problem.

Re: M4a metadata

M4a files don't have id3 tags. They use their own metadata format that Cog currently does not read.

Re: M4a metadata

Oh, I see.  I just assumed since I edit them in iTunes in the same way I would an MP3, that they worked with the same principle.  Sorry to have bothered you!

I'll move this to feature requests.

Re: M4a metadata

This is a biggie for me as I have a lot of "liberated" iTunes Store tracks in M4A format. One solution is to convert them all, en masse, to another format like MP3 or OGG with something that can read the M4A metadata but that's a dirty dirty workaround.

Re: M4a metadata

Me, too. Me, too!

Am slowly converting much to AppleLossless. I have nothing against iTunes but eventually all music is going to reside on one server and I plan to keep my own world separate using Cog.

Re: M4a metadata

Hmm, songbird seems to have a copy of the taglib library that supports m4a. Isn't open source great?
