  • 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 (...)

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages.

  • Add multiple audio files to video at specific points using FFMPEG

    7 août 2012, par Pascal Beyeler

    I am trying to create a video out of a sequence of images and various audio files using FFmpeg. While it is no problem to create a video containing the sequence of images with the following command :

    ffmpeg -f image2 -i image%d.jpg video.mpg

    I haven't found a way yet to add audio files at specific points to the generated video.
    Is it possible to do something like :

    ffmpeg -f image2 -i image%d.jpg -i audio1.mp3 AT 10s -i audio2.mp3 AT 15s video.mpg

    Any help is much appreciated !

    EDIT :

    The solution in my case was to use sox as suggested by blahdiblah in the answer below. You first have to create an empty audio file as a starting point like that :

    sox -n -r 44100 -c 2 silence.wav trim 0.0 20.0

    This generates a 20 sec empty WAV file. After that you can mix the empty file with other audio files.

    sox -m silence.wav "|sox sound1.mp3 -p pad 0" "|sox sound2.mp3 -p pad 2" out.wav

    The final audio file has a duration of 20 seconds and plays sound1.mp3 right at the beginning and sound2.mp3 after 2 seconds.
    To combine the sequence of images with the audio file we can use FFmpeg.

    ffmpeg -i video_%05d.png -i out.wav -r 25 out.mp4
