  • 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 (...)

  • I have a file that purports to be "uncompressed mov" that I want to convert to raw using ffmpeg

    9 août 2015, par Lyman Hurd

    I am running Ubuntu. Here is what I receive and also cannot play the movie with vlc or totem, however the sender insists that these files play on a Mac using QuickTime. Thoughts as to what might be wrong ?

  • How can I fix a damaged MP4 ?

    29 juillet 2015, par d3pd

    I have a video of just under an hour recorded but it appears to be damaged somehow. The file format is h264 MP4 and the file size is 2.3 GB, so I’m confident that the information is there, just that the file format is damaged. How could I approach fixing it ?

    So far, I’ve tried a simple ffmpeg copy operation :

    >ffmpeg -i video_28_07_2015_15_16_05.mp4  -c copy out.mp4

  • Android FFMPEG library crashes on Lollipop

    27 juillet 2015, par Laurent Gorse

    I’m using this open-source library to encode RTMP streams for my live streaming app :

    https://github.com/cine-io/cineio-broadcast-android

    The library is based on FFMPEG with libRTMP, and is open-source. It build the following native shared library :
    https://github.com/cine-io/ffmpegbridge

    Which relies on this :
    https://github.com/cine-io/android-ffmpeg-with-rtmp

    The issue is Lollipop compatibility. There’s a notorious issue where libraries need to be recompiled with PIE, but usually the thrown error is specific and states that "all binaries must be compiled with PIE".

    However, as soon as I start streaming on Android 5.+, this is the error I get from the backtrace :
