Mutagen updates ID3v1 tags but does not save ID3v2 tags about mutagen HOT 4 CLOSED

If there are no ID3v2.x tags yet mutagen does not automatically add them. You need to do some check like:

if audio.tags is None:
    audio.add_tags()

from mutagen.

Thanks, but the file already has ID3v2 tags (as shown in the example output). Adding a print(mutagen.File(filename).tags.pprint()) just before audio = ID3(filename) produces this:

COMM==eng=This is a comment
COMM=ID3v1 Comment=eng=This is a comment
TALB=Programme Name - Series 01
TCON=Comedy
TDRC=1922
TIT2=Programme Name
TPE1=Programme Name
TPE2=Programme Name
TRCK=1

In any case, audio.tags doesn't seem to be the right thing:

Traceback (most recent call last):
  File "/Users/me/bin/retag.py", line 18, in <module>
    if audio.tags is None:
AttributeError: 'ID3' object has no attribute 'tags'

from mutagen.

@unikitty37 The issue seems to be not writing the file, but the verification with the id3v2 utility, which does not support ID3v2.4. Either verify with e.g. mutagen-inspect or another tool actually supporting v2.4 tags, or save v2.3 tags by passing v2_version=3 to the save call.

I am closing this. I tried your script directly and it does save the ID3v2.4 tags. The old id3v2 utility does not support that. Saving with v2_version=3 makes it visible in that utility as well.

(BTW, shouldn't that v2 parameter in the list be v2_version? :)

Docs are fixed with 3cbcc1b
