Description Gale Andrews 2012-07-24 05:00:17 UTC
Created attachment 301 [details]
MP3 files with TDRC (no TYER) and TDRL id3v2.4 tags

See attached "TDRC TDRL.zip" containing TDRL.mp3 which has a TDRL v2.4 tag and
TDRC only.mp3 which has a TDRC v2.4 tag (but no v2.3 TYER tag).

It is surprising that TDRC is not read as src/ImportMP3.cpp states in line 338
what happens when TDRC and TYER are both encountered and so TDRC only is read
(which works correctly):

> When libid3tag encounters the "TYER" tag, it converts it to a
> "ZOBS" (obsolete) tag and adds a "TDRC" tag at the end of the
> list of tags using the first 4 characters of the "TYER" tag.
> Since we write both the "TDRC" and "TYER" tags, the "TDRC" tag
> will always be encountered first in the list.  We want use it
> since the converted "TYER" tag may have been truncated.

Demoting this to P4 as we know we have a generic and much broader problem with our poor handling of metadata.
Comment 3 Peter Sampson 2020-06-14 10:10:40 UTC
There is no proper release note provided by Gale either
Comment 4 Peter Sampson 2020-06-14 10:18:08 UTC

Comment 5 Leland Lucius 2021-02-17 06:08:13 UTC
Actually, these are broken files.  MediaInfoOnline doesn't see the tags and foobar doesn't display the value either.  And several Linux utes have issues with them as well.

Oh, and the tags aren't ID3V2.4 either.  Dumping the headers shows them as ID3V2.3.

I think this should be closed as NOT-A-BUG

(In reply to Leland Lucius from comment #5)
I agree.
