  • 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.

  • capture attribute to show the camera directly

    29 août 2017, par PKnight

    Dialog Box

    I would expect specifying the capture attribute to show the camera directly, rather than having to navigate through the dialog boxes above.
    I want the camera to go directly and I can record a video.

    <input type="file" accept="video/mp4,video/x-m4v,video/*" capture="camcorder" />

    I tried in several ways, but none worked. It’s always shows the dialog box to choose a camera. Can anybody help me ? Thank you

  • Stack architecture for handling video uploadings

    18 septembre 2017, par Lunf

    I have Springboot app (on EC2 xlarge) which handle multi-part upload video from mobile apps. The average video file is 250 350MB which currently stored in local disk before ffmpeg thread is started to convert and upload to S3 then will be removed from local disk.

    The problem is the app server could not keep up with number of uploads concurrently (5 videos), and CPU, RAM is maxed out.

    My question is what is the strategies (architecture) to scale in order to handle more uploads concurrently and should I need to rewrite the app server in specific way to meet my goal, let say 50 videos.

    Thank you

    i really want a way i can be able to map every input stream to have an output stream that can be accessed separately from the other like maybe if i need the first stream maybe i will just

    ffplay http://localhost:8090/feed1.ffm

    and if i need the 7th stream i will just

    ffplay http://localhost:8090/feed7.ffm

    Please can someone help me crack this issue. FFmpeg dont have complex examples for my current situation.
