ID3 is MP3 specific, I think. You can use something like "vorbiscomment
-l input.ogg" to view the metadata in your ogg output (or simply "ffmpeg
-i input.ogg"). Also, you won't need to use -map_meta_data with a recent
FFmpeg because it will automatically attempt to copy the metadata from
input to output.
