  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • MediaSPIP Init et Diogène : types de publications de MediaSPIP

    11 novembre 2010, par

    À l’installation d’un site MediaSPIP, le plugin MediaSPIP Init réalise certaines opérations dont la principale consiste à créer quatre rubriques principales dans le site et de créer cinq templates de formulaire pour Diogène.
    Ces quatre rubriques principales (aussi appelées secteurs) sont : Medias ; Sites ; Editos ; Actualités ;
    Pour chacune de ces rubriques est créé un template de formulaire spécifique éponyme. Pour la rubrique "Medias" un second template "catégorie" est créé permettant d’ajouter (...)

  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • OpenShift — installing ffmpeg

    2 juillet 2016, par aweeeezy

    I’m new to deploying web apps — I just started looking into hosting plans yesterday morning when I settled on OpenShift. I have my app running, but it depends on node-youtube-dl which returns this error when trying to download a video from a link :

    Error: Command failed: WARNING: m_djk1RQ2Ew: writing DASH m4a. Only some players support this container. Install ffmpeg or avconv to fix this automatically.
    
ERROR: ffprobe or avprobe not found. Please install one.

    So I searched around for awhile and kept returning to the same list instructions for how to install ffmpeg on OpenShift :

    cd $OPENSHIFT_DATA_DIR
    
mkdir bin
    
wget http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz
    
wget http://ffmpeg.org/releases/ffmpeg-2.0.1.tar.gz
    

    
tar -xvf yasm-1.2.0.tar.gz
    
cd yasm-1.2.0
    
./configure --prefix=$OPENSHIFT_DATA_DIR/bin --bindir=$OPENSHIFT_DATA_DIR/bin
    
make
    
make install
    
export PATH=$OPENSHIFT_DATA_DIR/bin:$PATH
    

    
cd $OPENSHIFT_DATA_DIR
    
tar -xvf ffmpeg-2.0.1.tar.gz
    
cd ffmpeg-2.0.1
    
./configure --prefix=$OPENSHIFT_DATA_DIR/bin --bindir=$OPENSHIFT_DATA_DIR/bin
    
make
    
make install

    Now my ~/app-root/data has ffprobe in it as well as some other codec related things, but node-youtube-dl still returns the same error saying I don’t have the necessary codecs installed. Here’s a listing of the contents of my data directory on OpenShift :

    -rwxr-xr-x.  1  11024048 Jul  2 01:51 ffmpeg
    
-rwxr-xr-x.  1  10967408 Jul  2 01:51 ffprobe
    
-rwxr-xr-x.  1  10611184 Jul  2 01:51 ffserver
    
drwx------. 10      4096 Jul  2 01:51 include
    
drwx------.  3      4096 Jul  2 01:51 lib
    
drwx------.  4        29 Jul  2 01:51 share
    
-rwxr-xr-x.  1   2116650 Jul  2 01:15 vsyasm
    
-rwxr-xr-x.  1   2115479 Jul  2 01:15 yasm
    
-rwxr-xr-x.  1   2102821 Jul  2 01:15 ytasm

    I really want OpenShift to work because it’s the last step to finishing off this one app before I move onto new projects — I don’t want to switch to paid hosting that will allow me to install stuff because I won’t be ready to determine an appropriate plan until a few months from now. That leaves me with trying to get ffmpeg to compile properly on OpenShift...so either a) I’m ignorant and it has long since been determined to be impossible by the OpenShift community or b) I’m ignorant and there’s a simple thing I’m doing wrong when building my codec libraries.

    Anybody out there know what’s wrong or had success installing these codecs before ? I’d greatly appreciate some guidance !

  • Can x264 be used from Java code via JNI to decrease the resolution of RTMP streams ? [on hold]

    5 septembre 2016, par Orr151

    I would like to implement a custom RTMP transcoder to HLS format in Java. As the repackaging itself seems to be relatively clear and doable in Java, then I found the modification of the video resolution a bit challenging in Java. My plan is to avoid using existing solutions like FFmpeg or at least minimize the amount of 3rd party frameworks/tools integrated with my component.

    After some research it seems that reusage of JCodec and Xuggler can be challenging as both project are idle for a while. Also I’m not sure if their performance is acceptable. That’s why I would like to integrate directly with x264 library via JNI from Java code.

    Is integration with x264/libx264 from Java code to decrease resolution/bitrate doable and is it a good idea ? Could you please suggest any other solutions ?

    Thanks !
