  • 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 (...)

  • ffmpeg motion interpolation alternatives or speedup

    27 décembre 2022, par Ural

    I use ffmpeg to create videos, it is awesome tool. I create videos from pictures and need to make them as smooth as possible. I found, that what I need called 'motion interpolation'. I started to search all forums, and found only 3 things can help me : slowmovideo, butterflow and new ffmpeg's filter minterpolate.

    



    slowmovideo needs many configuration, I was not able to get it to work as I want.
with butterflow, I tried anything. From installing OpenCL, OpenGL and other stuff to switching to nvidia binary drivers and installing all sdk tools and cuda. It never worked. Some error about cuda, and google don't know about it.

    



    So third option was the only one available. When I tried it, it did exactly what I want ! But it is incredibly SLOW. I have 8-core CPU, and it processes about 0.1-0.3 fps. And uses just 1 CORE, no video card.

    



    Is there any ways to motion interpolate frames on GPU or on CPU but faster ? Only GNU/Linux

  • mimic : drop AVPicture usage

    mimic : drop AVPicture usage

    Work on the AVFrame references directly.
    

    Instead of setting up a flipped/swapped "view" on the pictures,
    
flip/swap them when returning decoded frames to the API user.
