  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • 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 overlay video over image using movie filter resulting video with no sound

    22 février 2021, par Herahadi An

    I want to overlay srinked video on the top of single image.
I use movie filter to do that. like this

    


    ffmpeg.exe -loop 1 -i Coronavirus00000000.jpg -vf "movie=C\\:/\Users/\Toshiba/\Pictures/\test vcp/\shopi pro.mp4,scale=1180:-1[inner];[in][inner]overlay=70:70:shortest=1[out]" -y out.mp4


    


    It's work. but the problem, the audio from video is removed. The final video out.mp4 has no sound, even though the original video has.

    


    I have read answer on this threat FFMPEG overlaying video with image removes audio

    


    That recommend to Change into ...[padded]overlay=0:0" -y ... Or add -map 0:a

    


    But I don't understand how to implement that answer into movie filter

  • Increase the sound of the first input in certain moments

    22 mars 2023, par Ali Azmoodeh

    I have a code that has two inputs. The first entry is played with a 2 second delay. The second entry is played with a 1 second delay. These entries are repeated as the video progresses. The volume of the two inputs sometimes overlaps

    


    when this happens I want the volume of the first input to be 1 and the volume of the input The latter should be set to 0.3
