Transcoding audio files and preserving audio tags.

[Racecar56]

There are about 500 MP3 audio files that I want to be transcoded into Ogg, but ffmpeg doesn't preserve audio tags. Is there some kind of trick to make ffmpeg preserve the audio tags, another program I should be using, or some command that can be run after the ffmpeg process is complete?

This conversion will be running on 2 CPU cores as a batch job with GNU parallel compiled from the GNU website, on Ubuntu 10.10. Thanks!

Hi
With up-to-date versions of ffmpeg there is a 'map_meta_data' option.

Like this:-

ffmpeg -i input.mp3 -map_meta_data 0:0 -acodec libvorbis output.ogg

It doesn't make any effect, strangely enough. I know I got the order of the options right according to the order you put in that code.

EDIT: The SVN version of ffmpeg does have an effect with that option, but it still doesn't preserve everything. Very close, though.
