  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.

  • 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.

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    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.

  • What are the differences between FFmpeg and Libav ? [closed]

    16 septembre 2012, par Ken

    According to the first comment for this question, and i quote

    "Libraries with this name are provided from both the FFmpeg project
    and the Libav project, but they are mutually incompatible". So I think
    the answer depends on which libavcodec do you want to use.

    by user aland and wikipedia

    What are the differences that exist between this 2 projects ?

    I'm interested in video and audio encoding to H/X264, Mp3 and AAC with Mp4/Mkv containers ; but more importantly i would like to start with a reliable and up to date library with a permissive license and widely supported on as many platforms as possible.

  • Cross-compile ffmpeg for arm64 on x64 host machine (macOS) ?

    13 juin 2021, par waldenCalms

    I need to cross-compile ffmpeg for arm64 (M1 Macs, to be specific) from my x64 host Mac. I am able to build ffmpeg for my host architecture without issues (i.e. I have a working x64 build script and all the pre-requisites installed), but now need to modify my script to build for arm64.

    


    First of all, is this even possible / supported ? If so, how ?

    


    The official ffmpeg compilation guide doesn't mention anything helpful. I have looked at several code snippets online and tried using the following configure arguments, with no luck :

    


    --enable-cross-compile \
--arch=arm64 \


    


    I get the following error :

    


    libavutil/aarch64/bswap.h:38:13: error: invalid instruction mnemonic 'rev'
