[FFmpeg-user] Metadata problem from mp3 to ogg

[hallucinet at free.fr]

Hi everybody, this is my first message. I searched the archive about my problem, actually found answers, but they somehow seem to not apply to my very problem :

I cannot pass the metadata from my mp3 files to ogg files. The mp3s appear to have both Id3V1 and Id3V2 metadata, correctly tagged. When I lauch the ffmpeg command, it reads and displays what seem to be the ID3V2 tags of the mp3 file. But I cannot retrieve them in the ogg file.

#id3v2 -l Elephant_Rouge-01-Splash.mp3                               
id3v1 tag info for Elephant_Rouge-01-Splash.mp3:

#id3v2 -l Elephant_Rouge-01-Splash.ogg 
Elephant_Rouge-01-Splash.ogg: No ID3 tag

(the file plays fine, BTW)

I tried a lot of outfile:infile combinations, only 0:0 produced no errors, but still no tags in the resulting files... :(

What is crutial to me are the Song name and track #

Any idea of what I'm doing wrong ?

Thanks
