youtube-dl.exe 4LfvziNR2KM -xf bestaudio[acodec=opus]

works great, gives ogg container with .opus extension. However I need to change filename extension to .ogg or any other which Samsung Music recognizes as music

It is plain filename change, not any reencoding

I tried this, but does not work as expected with -x, it downloads and saves video as .ogg but still gives .opus as final result, and deletes .ogg video file

youtube-dl.exe 4LfvziNR2KM -xf bestaudio[acodec=opus] -o "%(title)s-%(id)s.ogg"

How to do it? I ask for your help

Do not hardcode the extension.
