  • MediaSPIP Core : La Configuration

    9 novembre 2010, par

    MediaSPIP Core fournit par défaut trois pages différentes de configuration (ces pages utilisent le plugin de configuration CFG pour fonctionner) : une page spécifique à la configuration générale du squelettes ; une page spécifique à la configuration de la page d’accueil du site ; une page spécifique à la configuration des secteurs ;
    Il fournit également une page supplémentaire qui n’apparait que lorsque certains plugins sont activés permettant de contrôler l’affichage et les fonctionnalités spécifiques (...)

  • Configuration spécifique d’Apache

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • ffmpeg and ffserver, rc buffer underflow ?

    26 avril 2017, par Dove Devic

    I am attempting to write a simple streaming server for a project. I have an AWS Linux machine that will be running ffserver. Curently, as it stands, my config file looks like the following :

    #Server Configs
    
HTTPPort 8090
    
HTTPBindAddress 0.0.0.0
    
MaxHTTPConnections 2000
    
MaxClients 1000
    
MaxBandwidth 1000

</stream>

</stream>

    I then am capturing my Webcam and sending it up to the server using the following command :

    ffmpeg -f dshow 
    
       -i video="Webcam C170":audio="Microphone (Webcam C170)"

       -ar 44100  
    
       -y http://:8090/feed1.ffm

    When I run this however, I get the following output from my console :

    And on my viewer, I just get a black screen.

    Is there something I’m missing ? Searching lead to nothing on "increasing qmax" or anything similar to what ffmpeg complained about. There have been questions asked here, but nothing has been done/answered.

    Thanks in advance

  • Encode videos to send with WhatsApp

    28 avril 2017, par piegames

    I have a series of PNG images of a video I rendered and now I want so send it via WhatsApp. I used to encode my videos with the command from this answer, but apparently the videos can only be played from WhatsApp web ; on the phone I still get an error message. How do I convert them so that they can also be played on phone ?

    Command used :

    %PATH_TO_FFMPEG%\ffmpeg.exe -i paint\out%04d.png -c:v libx264 -c:a aac ./videos/out7.mp4
