  • 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 (...)

  • imagemagick gradient mask file creation

    6 avril 2016, par lang2

    I’m playing with this creative script here : http://www.fmwconcepts.com/imagemagick/transitions/. The plan is to mimic what happens with the script with ffmpeg and generate video with transition effects between pictures. My current understanding is this :

    1. I have two pictures A and B.
    2. I need in between a couple of pictures (say 15) that are partially A and partially B.
    3. To do that I use the composite -compose src-over A.jpg B.jpg mask-n.jpg out.jpg command.
    4. During the process, the mask-n.jpg gets generated automatically that gradually change from all black to all white.
    5. Depends on the mathematically equations, the way the transition effect looks is different.

    In one of the example, Fred the author gave this :

    convert -size 128x128 gradient: maskfile.jpg

    This will generate a image like this :
    enter image description here

    This is partially black and partially white. For the transition to work, I’ll need an all white one and an all black one and a couple of others in between. What’s the magical command to do that ?

  • FFMPEG Images to video - 'file not found' error in command - I'm sure it's something obvious

    8 août 2017, par jgads

    I’m running this command on my Android phone with an FFmpeg library. It works great for combining videos into one resultant video, but not with images. Here’s the command :

     -framerate 4 -start_number 0 -i '/storage/emulated/0/Pictures/phototest/%3d.jpg' -c:v libx264 -r 30 -pix_fmt yuv420p /storage/emulated/0/Pictures/phototest/result.mp4

    The error is :

    '/storage/emulated/0/Pictures/phototest/%3d.jpg': No such file or directory

    The images are just consecutively named, e.g. 1.jpg, 2.jpg and so on, and they’re definitely there - though I think FFMPEG is taking the image file name literally rather than interpreting it. I’m missing something obvious here, I’m sure of it. I looked round StackOverflow and the whole ’%3d’ wildcard is supposed to work ! Any ideas ?

    EDIT : Running the command with just the first image (1.jpg) works fine. Definitely an issue with the wildcard. In addition, running the command without the image path in quotes doesn’t seem to work either.

    EDIT 2 : Adding ’img’ in front of every file so that it it’s ’img1.jpg’, ’img2.jpg’ and so on doesn’t work either. Is there a way to pass multiple images separated by ’|’ like the concat command ?
