  • 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 (...)

  • 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 (...)

  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • how to replace ffmeg's h.264 decoder ?

    26 novembre 2014, par myqiqiang

    Since FFMPEG take too much CPU resource and we can hardware decode in IOS8 ,so i want to replace its decoder with hardwaredecoder.

    but how ? i search in google but get nothing.

    and my thought now is to replace this method with my decoder
    _pCodec = avcodec_find_decoder(m_pCodecCtx->codec_id);

    here is what i want :
    1、if there is a way to replace the h.264 decoder ?
    2、if there exists,then how to do that ?
    3、if there any articles may help me ?

  • ffmpeg error when using non root user

    29 août 2014, par mkern

    I have installed ffmpeg and it works perfect if you are root or using sudo but it errors out when trying to use it as a non-root user. I have performed the same install on a test VPS and it installs without issue so it appears to be isolated to this cPanel server. I haven’t been able to identify why.

  • how to use guardianproject's android ffmpeg library ?

    21 octobre 2013, par Blaze Tama

    First, this is my first time "playing" with ffmpeg, so please bear with me.

    Generally, i dont understand ffmpeg even a little bit. So i did lot, lot of researches (and also trial & error) and i finally found this project and its library

    So i was successfully created the ffmpeg and sox binary file, and i put it in the raw folder at the library project (from the link i shared).

    Now, i want to use the library for my project, but i still cant do it. I tried to use some methods in the FfmpegController like combineAudioAndVideo and more but its not working (yet).

    I dont post the error here since i still do my trial&errors (and the error change regularly) but im getting tired now.

    EDIT

    This is what i did :

    private FfmpegController ffController;

       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);

           File file = new File(Uri.parse("android.resource://com.my.package/" + R.raw.test).getPath());
           try {
               ffController = new FfmpegController(this, file);
           } catch (FileNotFoundException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
           } catch (IOException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
           }

           MediaDesc desc = ffController.combineAudioAndVideo(R.raw.test, R.raw.musictest, "test.mp4", null);
       }

    The combineAudioAndVideo always error because wrong parameters. It needs MediaDesc but i dont know how to do it.

    I will be very happy if you can share your working code if you have done the ffmpeg processing with this library.
