  • 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 (...)

  • libavfilter - reconfigure filter graph using avfilter_graph_parse_ptr returns -22

    16 juillet 2021, par Rahul

    I am using transcode.c sample from ffmpeg examples and it is working as expected. It uses avfilter_graph_parse_ptr to setup filter graph and it works fine.

    


    However, I need change filter graph dynamically and there avfilter_graph_parse_ptr fails. It returns -22. I am not certain if it is a valid operation to do (reconfigure) ? If it is possible, does it require more than avfilter_graph_parse_ptr and avfilter_graph_parse_ptr ? libavfilter documentation doesn't say anything about reconfigure or reset existing graph.

    


    I can create a new graph but I am avoiding it since it is affecting the existing buffers.

    


    Thank you for your insight.

    


  • FFmpeg av_hwdevice_ctx_create returns ENOMEM

    4 mars 2021, par lnogueir

    I am trying to perform h264 video encoding on a GPU using the ffmpeg's vaapi library.

    


    I have been following this example from ffmpeg Github repo.

    


    It fails for me here :

    


    AVBufferRef* vaapi_encoder;
int err = av_hwdevice_ctx_create(&vaapi_encoder, AV_HWDEVICE_TYPE_VAAPI,
                                 NULL, NULL, 0);


    


    This returns -12, which maps to ENOMEM (out of memory) error, but that doesn't make sense to me because I have plenty of memory.

    


    For reference, this is my output after running 'vainfo' :

    


    libva info: VA-API version 1.7.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so

  • php fread returns empty after one time of execution for popen

    20 avril 2021, par Hamed

    I'm trying to get real-time output from ffmpeg command with popen, but it returns empty after one time of execution in the loop.

    


    &lt;?php&#xA;&#xA;$a = popen(&#x27;ffpb -i mymovie.mp4 -vf subtitles=subtitles.srt mysubtitledmovie.mp4 2>&amp;1&#x27;, &#x27;r&#x27;);&#xA;&#xA;&#xA;while (true) {&#xA;    $b = fread($a, 2096);&#xA;&#xA;    var_dump($b) . "<br />\n";&#xA;&#xA;    ob_flush();&#xA;    flush();&#xA;&#xA;    sleep(1);&#xA;}&#xA;

    &#xA;

    The output : :

    &#xA;

    mymovie.mp4:   0%|          | 0/61080.0 [00:00&lt;?, ? frames/s]"&#xA;string(105) "Unexpected exception: &#x27;ascii&#x27; codec can&#x27;t encode characters in position 43-47: ordinal &#xA;not in range(128)&#xA;"&#xA;string(0) ""&#xA;string(0) ""&#xA;string(0) ""&#xA;
