  • Amélioration de la version de base

    13 septembre 2013

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Menus personnalisés

    14 novembre 2010, par

    MediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
    Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
    Menus créés à l’initialisation du site
    Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...)

  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.
    Version mono serveur
    La version mono serveur consiste à n’utiliser qu’une (...)

  • Error in ffmpeg conversion

    9 avril 2015, par Adam Mo.

    I have a VPS 1G RAM with CentOS 6 i386 minimal installed and installed ffmpeg by ffmpeginstaller.com to setup clipbucket 2.7 in the VPS.
    when I test the ffmpeg by this command :

    wget "http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_720p_surround.avi"
    
ffmpeg -i big_buck_bunny_720p_surround.avi -vcodec libx264 big_buck_bunny_720p_surround-H264.avi

    by following this tutorial I get error

  • Using ffmpeg to generate multiple resolutions with the exact same keyframe positions

    2 novembre 2014, par bacon overlord

    There are a bunch of resources on how to use ffmpeg to convert X to Y and so forth but I can’t seem to be able to generate different resolutions of the same file with the same keyframe and frame positions.

    The keyframe positions are important because they allow the player to jump from one bitrate to another.

    These videos are intended for Flash.

    I keep on getting results like this from the validation tool.

    failed on frame 1670
    
[FrameInfo 1670, type 9, timecode 23565, seekable 1670]
    
[FrameInfo 1670, type 9, timecode 23565, seekable 1525]

    Even worse, sometimes it takes to re-ordering the frames

    failed on frame 1
    
[FrameInfo 1, type 9, timecode 0, seekable 1]
    
[FrameInfo 1, type 8, timecode 0, seekable -1]

    When trying to validate the sample videos that are installed with Adobe Flash Media Server they are ok

    Comparing files
    
0: G:\VOD\sample1_150kbps.flv
    
1: G:\VOD\sample1_500kbps.flv
    
2: G:\VOD\sample1_700kbps.flv
    
3: G:\VOD\sample1_1500kbps.flv
    
Index, Keyframes, and Timecodes are Validated across all files

    Sample ffmpeg command I run at different resolutions. Adobe Media Encoder is also producing video with different keyframe positions so I don’t know whats going on here.

    ffmpeg -i source.mp4 -vf scale=1270:720 -c:a copy output.flv
