  • 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 (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.

  • FFMPEG command not working on Ubuntu

    7 novembre 2016, par brijesh kumar

    I stuck with the command "anequalizer" in ffmpeg. I’m following the official documantation. It has example command in documentation like this

    anequalizer=c0 f=200 w=100 g=-10 t=1|c1 f=200 w=100 g=-10 t=1

    and when I run the command

    ffmpeg /home/overtatech-1/Music/jeena.mp3 -af "anequalizer=c0 f=200 w=100 g=-10 t=1|c1 f=200 w=100 g=-10 t=1" /home/overtatech-1/Music/jeena_new.mp3

    on console, I get error "c1:Command not found"

    Lenovo-G50-80:~$ ffmpeg /home/overtatech-1/Music/jeena.mp3 -af  "anequalizer=c0 f=200 w=100 g=-10 t=1|c1 f=200 w=100 g=-10 t=1" /home/overtatech-1/Music/jeena_new.mp3

  • Burn subtitles in a stop motion video, with hardware acceleration

    9 février 2020, par Belinde

    I’m trying to make a year long stop motion video with the images taken from a webcam. I’ve created a input.txt file with this format inside :

    ffconcat version 1.0
    

    
file 'amianthe201909031230.jpg'
    
duration 0.093034825870647
    

    
file 'amianthe201909031330.jpg'
    
duration 0.093034825870647

    The command I’ve crafted (mostly taken from the example in the official ffmpeg documentation) is :

    ffmpeg \
    
    -y \
    
    -hwaccel vaapi \
    
    -hwaccel_device /dev/dri/renderD128 \
    
    -hwaccel_output_format vaapi \
    
    -f concat \
    
    -i input.txt \
    
    -vf 'hwmap=mode=read+write+direct,format=nv12,ass=subtitles.ass,hwmap' \
    
    -c:v h264_vaapi \
    
    ~/amianthe.mp4

    But it badly fails with this output :

    I’m honestly lost : from my understanding, all the elaboration should be done directly in the video card memory, so I don’t understand why it’s converting the surface format. Is there some other parameter I must put in format ? What am I missing ?
