Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

How to encode specific metadata version in FFMPEG ?
11 février 2021, par Charlie BrittonI am batch converting lots of songs into shorter "Advert" songs for SHOUTcast and to be recognised as adverts by the server. The song must have
":Advert"
for both the title and the artist metadata tags. When I use the following command :


ffmpeg -i "$i" -c copy -vn -map_metadata -1 -metadata title=":Advert" -metadata artist=":Advert" -t 120 "adverts/ADVERT_$i"




I would expect it to output the song with only
":Advert"
as title and artist metadata but when I import it into the radio playout software (using ID3 1.x tagging) the metadata has not copied across and is therefore lost. Output from ffmpeg :

I believe this is happening because the tag names are different (e.g. title should be

Isolating/separating vocals from audio by FFMPEG
21 février 2023, par JonyI remove the vocals from music via


ffmpeg -i song.mp3 -af pan="stereo|c0=c0|c1=-1*c1" -ac 1 karaoke.mp3


The output is the music without vocals (not completely but fairly good).


I wonder what is the command to make the output separated vocals (vocal only) ?


I mean how to save the separated vocals in an audio file ?
