  • 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 terminal : How can I re-encode a video file using all the parameters copied from another video ? [closed]

    5 décembre 2022, par Lever

    I have two videos A and B. How can I re-encode B using ALL the parameters of A ?
I would like to use both A and B as inputs, but all parameters are extracted from A, then B is re-encoded with the A-parameters including both video and audio. Is there a simple command to copy ALL the parameters of A ?

    


    Thanks !

    


    I know the typical parameters of a video includes the resolution, fps and so on. But it seems that I always miss something rather than get ALL the parameters to make A and B the same.

    


    The background is that I need to concatenate about 100 videos, but only a few of which has lower quality than others. I don't want to re-encode all of them. Therefore I'm trying to re-encode the lower ones to match the others, and then I can use the file-level concatenation command avoiding re-encode all of them.

    


  • Android FFMPEG slow

    22 juillet 2016, par Thommy

    I create a video with an overlay fading to merge this later with another video to get an overlayed video.
    Merging and co are working fine and fast, but creating the overlay-video with a fading picture is very slow (3 to 4 fps). Other operations like scaling run with 10 to 200 fps.
    Here is my ffmpeg command for creating the ovleray video.

    ../binary/ffmpeg -loop 1 -i ../overlay_0.png -t 21.534 -vf scale=1280:720,fade=in:st=21.034:d=0.05,fade=out:st=21.534:d=2.0 -pix_fmt rgba -vcodec png -threads 5 -preset ultrafast ../outfile.mp4

    Did I miss any commands to speed this up ?
