  • 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 loop video overlay smooth

    20 novembre 2018, par Young King

    I have :

    • 1 image(background.png)
    • 2 videos ( like a sticker will be added to image background by overlay options)

    videoA.mp4 (duration x second)
    videoB.mp4 (duration y second)

    I want to create smooth video by loop videoA and videoB with duration is multiples of x and y

    For example :
    x = 4s
    y = 6s

    Video output will be have duration 12s, videoA loop 3 times, videoB loop 2 times

    How can I create FFMPEG command.

  • ffmpeg - How to change the filter-paramaters depending on time oder framenumber ?

    2 mars 2020, par LookAndSee

    Hallo to all userse and helpers here in this forum ! Thank you, i am new and i have found allready a lot of solutions.

    Now I want to ask, if someone can help me :

    I have a Movie about 30 seconds made of 1 image.
    Now I want to pixelate depending on time or framenumber - every time a litlle bit less.
    My code so far :

    ffmpeg -i in.mp4 -vf scale=iw/n:ih/n,scale=niw:nih:flags=neighbor out.mp4

    where n should be the framenumber 1 to 900.
    this scould also be t+1 for slower change.

    the stars are gone - so i mean n times iw:n times ih :

    error-massage :

    undefined constant or missing ’(’ in ’n’
    error when evaluating the expression ’ih/n’
    maybe the expression for out_w :’w/n’ or for out_h :’ih/n’ is self-referencing.
    failed to configure output pad on paresed_scale_0
    error reinitializing filters !
    failed to inject frame into filter network : invalid argument
    error while processing the decoded data for stream #0:0

    Do you have some suggestion plaese - Thank you in Advance

  • Syncing decoded video using Ffmpeg

    30 juin 2012, par Infiniti Fizz

    I am using Ffmpeg to decode and play video files. I have currently got the video playing and the audio playing at as fast as the CPU can decode and display them. The problem is that I want to play the video and audio in sync using the system clock.

    I've searched around for some help but can't find anything substantial other than dranger's tutorial 05 but I don't really understand what he is doing because my program isn't written in the same way as his.

    I am using mjpeg files and so the pts seems to be retrieved every single time a frame is decoded, I have multiplied the pts by the time_base as dranger does to get the value in seconds but the resolution seems to be only seconds and so I get the value "6" 25 times and then "7" 25 times as the video runs at 25 frames per second.

    Is there not a more accurate value ? Or way to get a more accurate value and if so, how would I go about syncing to this value ? I am using SDL to display the value so can I just use a SDL_Delay() of the value I get ?

    Thanks for your time,
