  • 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.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • 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

    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.
    The documentation of the use of this installation script is available here.

  • How to modify x264 source code to get motion search time [on hold]

    21 octobre 2017, par Yicheng Li

    I am a new member of stack overflow, I hope you guys can help me solve this problem.
    I am now using x264 with ffmpeg to encode some raw video, I was asked how much time the motion search would cost in libx264 video coding. Therefore, I need to modify the code, I tried put the clock around the switch sentence in the encoder/me.c
    clock start

    clock end
    After compiling the source code and run a test,
    it shows that the time is very small and it seems I am actually getting the time each macro block spent on motion search.

    So, how should I modify the x264 source code to get the time duration in motion search.

    Big Thanks.

  • Efficient ogv video conversion in Linux

    26 mai 2023, par Marco Ferro

    I have a ogv video file of 113MB. I converted it to mp4 and reduced its size from command line through ffmpeg. The resulting video is around 12MB sized, but the quality is really bad. I would like to get a better quality at cost of a higher file size, but I don't know how. 
Can you suggest me a correct way to do that ?
