  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • 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.

  • Configuration spécifique d’Apache

    4 février 2011, par

    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.

  • Issue when streaming some TV channels threw ffMpeg

    7 octobre 2016, par Raphael Serievic

    I am trying to stream a TV Tuner feed with ffMpeg through udp.

    The ffMpeg command line I use is the following :

    ffmpeg.exe -i udp://@239.255.255.9:1234 -map 0:p:1317:0 -profile:v baseline -crf 30 -preset ultrafast -vcodec libx264 -r 25 -vf scale=720:576-b:v 500k -f rtp udp://10.150.112.107:15048/ -map 0:p:1317:1 -acodec pcm_mulaw -strict experimental -ar 8k -ac 1 -b:a 128k -f rtp udp://10.150.112.107:15032/

    Where :

    • 1317 is the program id (channel)
    • 10.150.112.107 is where I want to stream the TV channel
    • 239.255.255.9 is where I receive the original TV channel’s feed from my TV Tuner

    My problem is that with some program IDs it is working and with some others it is not : it is working with 1572 ("channel 10 hd") but not with 1317 ("7flix Sydney").

    The output of this command-line for channel 1572 (where it works) is the following :

    C:\Program Files (x86)\Tuner Manager\ServerModule> ffmpeg.exe
    
 -i udp://@239.255.255.7:1234 -map 0:p:1572:0 -profile:v baseline -crf 30 -prese

  • FFmpeg record live stream and make mp4 file closer to now to play at html5 video and should updated quickly

    17 novembre 2016, par Angel

    Now I am developing video clipping system with PHP and FFMpeg.
    Recording live stream from media server with rtmp protocol.
    Let’s suppose we are recording football and I want make highlight soon.
    so I can see live streams and also able to clip video.
    Please help me if anyone have idea.

  • Ffmpeg in Android Studio

    7 décembre 2016, par Ahmed Abd-Elmeged

    i’am trying to add Ffmpeg library to use it in Live Streaming app based in Youtube APi when i add it and i use Cmake Build tool the header files only shown in the c native class which i create and i want it to be included in the other header files
    which came with library how can i do it in cmake script or onther way ?

    This my cmake build script

    # Sets the minimum version of CMake required to build the native
    
# library. You should either keep the default value or only pass a
    
# value of 3.4.0 or lower.
    

    
cmake_minimum_required(VERSION 3.4.1)
    

    
# Creates and names a library, sets it as either STATIC
    
# or SHARED, and provides the relative paths to its source code.
    
# You can define multiple libraries, and CMake builds it for you.
    
# Gradle automatically packages shared libraries with your APK.
    

    
add_library( # Sets the name of the library.
    
             ffmpeg-jni

             # Associated headers in the same location as their source
    
             # file are automatically included.
    
             src/main/cpp/ffmpeg-jni.c )
    

    
# Searches for a specified prebuilt library and stores the path as a
    
# variable. Because system libraries are included in the search path by
    
# default, you only need to specify the name of the public NDK library
    
# you want to add. CMake verifies that the library exists before
    
# completing its build.
    

    
find_library( # Sets the name of the path variable.
    
              log-lib
    

    
              # Specifies the name of the NDK library that
    
              # you want CMake to locate.
    
              log )
    

    
# Specifies libraries CMake should link to your target library. You
    
# can link multiple libraries, such as libraries you define in the
    
# build script, prebuilt third-party libraries, or system libraries.
