beet convert not working?

[FlitPix]

Hi - I got my Tangara in the mail the other day and I've been trying to get my music collection sorted to work on it.

Currently, Tangara doesn't support AAC/ALAC files, so I've been trying to convert all of them to opus/ogg, using the command they have documented here under the supported audio formats section: beet convert format:aac --format=opus --keep-new -d ~/Backups/aac

The command, however, seems to do absolutely nothing. It copies my music to the backup directory I specified, and... nothing else (-v reveals nothing of note):

convert: Moving to /home/flitpix/Backups/aac3/artist/album/song.m4a
convert: Copying /home/flitpix/Music/artist/album/song.m4a

I'm still left with .m4a files, and beet list format:aac still lists all the songs that I don't want to be aac.

Is the Tangara documentation/command wrong, or is the command just not working as it should?

I'm using the latest Arch package on EndeavourOS.

convert config snippet:

convert:
  embed: no
  never_convert_lossy_files: yes
  format: opus
  copy_album_art: yes

EDIT: Other types of files (eg. FLAC) have no problems with being converted to opus so I'm convinced this is a bug. Since I've already posted this, I figure I'll wait a bit before making a new issue.

(As an aside, please update the IRC room topic to point here instead of Discourse.)

Figured out that, because AAC is lossy, I had to enable never_convert_lossy_files in the convert plugin config.

Additionally, if files already exist in the backup location, it will not convert (which is probably for the best, but was still not made very clear).

Hopefully this helps others!
