  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Playing RTSP stream in Android

    9 décembre 2014, par Kamil

    I’m trying to play video stream on Android device. Unfortunatelly I still get the same problem with MediaPlayer/VideoView. I’m searching for a few days, but still haven’t found any working solution.
    For test purposes I’m using MediaPlayer app from API Demos (API Demos/Media/MediaPlayer/Play Streaming Video).
    Here is code snippet for playing stream

    mMediaPlayer = new MediaPlayer();
    
mMediaPlayer.setDataSource(path);
    
mMediaPlayer.setDisplay(holder);
    
mMediaPlayer.prepare();
    
mMediaPlayer.setOnBufferingUpdateListener(this);
    
mMediaPlayer.setOnCompletionListener(this);
    
mMediaPlayer.setOnPreparedListener(this);
    
mMediaPlayer.setOnVideoSizeChangedListener(this);

    When I try to play stream I get this info from logcat
    http://pastebin.com/5Uib5CH5

    This is configuration of ffserver streaming the video

    Port 8090
    
BindAddress 0.0.0.0

    If anyone can advise me how to fix it, or at least indicate an mistake, I will be grateful.

  • ffmpeg fade filter installed but not working ?

    4 novembre 2011, par Astha

    I have php 5.1.6 running on my CentOS 5 server running Apache 2.2.3

    I installed ffmpeg library and my aim is to covert a set of images into a slideshow with the fadein/fade out effect per image swap.

    Command ffmpeg says :

Use -h to get full help or, even better, run 'man ffmpeg'

    and command ffmpeg -filters prints :

    firstly my ffmpeg was not having fade filter because it was giving error

    fade: filter not found

    so i installed the patch created vf_fade.c and made corresponding changes to Makefile and allfilters.c file of directory libavfilters in ffmpeg. configured it again then also ran commands 'make' and 'make install' Restarted the server but still its showing the same error

    fade: filter not found

    what should i do next ? if any more details needed please ask and all the helps and ideas and links will be appreciated.
