How to change Language of COMM frame with User Actions?
I own a lot of mp3 files where the language code of COMM frame is uppercase instead of lowercase. Kid3 mark those files with error "Must have ISO 639-2 language code, 3 lowercase characters"
So far so good. But it's boring to correct this by clicking "Edit..." file by file. First I wrote some scripts for using xdotool to automate the clicking, but this is a bit faulty.
Then I figured out how to work with User Actions within Kid3. Very nice feture. But I did not find any way to edit the language code of COMM frames. Is this somehow possible or is there another way to get this automated?
