  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.

  • FFMPEG hwaccel convert WEBM to MP4 video failed : could not find codec parameters

    1er juillet 2020, par Yen Nguyen

    I use FFMPEG to convert webm videos into mp4 format using a Nvidia GPU GeoForce GTX 1660 card on Windows 10. It has worked perfectly since the beginning for few months but now it's stopped working with strange error as below :

big-buck-bunny-trailer.webm: could not find codec parameters


    



    FFMPEG version and Nvidia driver version are the same as before it just crashed overnight without a clue. I tried Googling around and did update to the latest ffmpeg version as well Nvidia driver version but it still doesn't help.
If I switch to CPU decoder (without hwaccel arg) using libx264 it just works fine.
