  • 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 (...)

  • libavformat/mov : Fix memleaks when demuxing DV audio

    libavformat/mov : Fix memleaks when demuxing DV audio

    The code for demuxing DV audio predates the introduction of refcounted
    
packets and when the latter was added, changes to the former were
    
forgotten. This meant that when avpriv_dv_produce_packet initialized the
    
packet containing the AVBufferRef, the AVBufferRef as well as the
    
underlying AVBuffer leaked ; the actual packet data didn't leak : They
    
were directly freed, but not via their AVBuffer's free function.
    

    https://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket4671/dir1.tar.bz2
    
contains samples for this (enable_drefs needs to be enabled for them).
    

    Moreover, errors in avpriv_dv_produce_packet were ignored ; this has been
    
changed, too.
    

    Furthermore, in the hypothetical scenario that the track has a palette,
    
this would leak, too, so reorder the code so that the palette code
    
appears after the DV audio code.

  • Memory leak in ffmpeg or libav with Mac os x 10.8.2 ?

    26 mars 2013, par James491

    I've been developing a video player with FFmpeg and am experiencing some memory leakage. I am on a Mac OS X 10.8.2 and valgrind is unstable. A large memory leakage, about the size of the video itself, is leaked during av_read_frame. Also, memory leakage occurs with the simple code below, after avformat_find_stream_info. None of my programs, including the small one below, leak on my Windows computer. Any suggestions would be helpful. Should I report a bug to FFmpeg ? I am using the latest version of FFmpeg, 1.1.2. Memory leakage also occurs if I use ffplay, but not if I use VLC.

    #include <libavformat></libavformat>avformat.h>

    #include 
    

    
    int main(int argc, char* argv[]) {
    

    
        char              *video_addr = "/Users/###/Desktop/rawmovie.mov";
    
        AVFormatContext   *pFormatCtx;
    

    
        av_register_all();
    

    
        if (avformat_open_input(&amp;pFormatCtx, video_addr, NULL, NULL) != 0) {
    
            fprintf(stderr, "Could not open the video file\n");
    
            return -1;
    
        }
    

    
        if (avformat_find_stream_info(pFormatCtx, NULL) &lt; 0) {
    
            fprintf(stderr, "Couldn&#39;t find stream information\n");
    
        }
