  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang 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.

  • FFMPEG sepia filter

    24 avril 2017, par Alex Konetchy

    Can’t seem to figure out why my colorchannelmixer filter is not working with ffmpeg. It doesn’t appear to output any errors, but the ouput.mp4 video is just a 0 second long video with no thumbnail.

    Here’s the command I’m trying.

    ffmpeg -i video.mp4 -filter_complex \
    
"[0:v] colorchannelmixer=.393:.769:.189:0:.349:.686:.168:0:.272:.534:.131[f1];\
    
[f1] eq=1.0:0:1.3:2.4:1.0:1.0:1.0:1.0 [outv]" -map "[outv]" output.mp4

    And the output I receive.
