So basically I'm using FFmpeg Batch AV Converter (which is very good and I recommend) and I'm trying to convert all my music which is stored in FLAC, AAC and MP3 to Opus (OGG).
The problem is that I don't know what should I do so that the album cover is preserved in the conversion. As in, the metadata itself is copied to the Opus file, except the album cover.
Now of course I could add it later with a metadata editor, but it's too much work and it may even be unnecessary if there is a command to do that.
I currently use:
-c:a libopus -b:a 128k -vbr on -compression_level 10 -frame_duration 20 -application audio
Any help will be appreciated.
Thank you!
