  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    12 avril 2011, par

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

  • .MKV to .MP4 choosing the audio and subtitles ?

    11 décembre 2016, par Leo Letto

    The following stream belongs to a .mkv file with dual audio ;

    Stream #0:0: Video: h264 (High), yuv420p(progressive), 1280x960 [SAR 1:1 DAR 4:3], 29.97 fps, 29.97 tbr, 1k tbn, 59.94 tbc (default)
    
Stream #0:1(eng): Audio: mp3, 48000 Hz, stereo, s16p, 256 kb/s (default)
    
Stream #0:2(por): Audio: ac3, 48000 Hz, stereo, fltp, 192 kb/s
    
Stream #0:3(eng): Subtitle: ass (default)

    Which ffmpeg command should I use to create an output with the language in Portuguese, already with the English subtitles ?

    I found some commands that can extract the language-based caption that I specify, but I didn’t find anything related to selecting the audio type.

    This is the entire output from ffmpeg :

  • How to Compile FFmpeg with x264 and libfdk-aac for Android

    12 novembre 2016, par Codeveloper

    Everyone.

    Please understand that i use the wrong english.

    I want to make encoding application using FFmpeg.

    I was successfully building NDK with FFmpeg.

    However, to encode H.264 video made had failed( Codec not found.. ).

    I was learned that libx264 is need encode H.264 and libfdk-aac is need encode AAC.

    so I tried to build the libx264 and libfdk-aac, But does not easily cross-compile.

    Please tell me what I did wrong.
