Copying all tags from one file to another #125

Open brauliobo opened 1 year ago

brauliobo commented 1 year ago

Hi, I would like to copy all tags from an mp3 file to an m4a (aac) file, including private tags and cover embedded images. How to do it in Ruby? I'm already using taglib-ruby at https://github.com/brauliobo/media-downloader-bot

FFMpeg -map_metadata 0 ignore private tags and embedded images.

I've tried exiftool but it also failed:

I've managed to copy everything with kid3-cli:

kid3-cli -c 'select in.mp3' -c copy -c 'select out.m4a' -c paste -c save
