  • 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 (...)

  • why doesn't ffmpeg name files with sequence after using strftime ?

    5 décembre 2016, par user2030856

    I would like to know why ffmpeg stops naming my files with a sequence number (%03d) when using -strftime 1 ?

    for example : filename_%Y-%m-%d_%03d.ts

    I need to get filename_YEAR_MONTH_DAY_SEQUENCE#.ts

  • Fast seeking ffmpeg multiple times for screenshots

    7 mars 2017, par user3786834

    I have come across http://askubuntu.com/questions/377579/ffmpeg-output-screenshot-gallery/377630#377630, it’s perfect. That has done exactly what I wanted.

    However, I’m using remote URLs to generate the screenshot timeline. I do know it’s possible to fast seek with remote files using https://trac.ffmpeg.org/wiki/Seeking%20with%20FFmpeg (using -ss before the -i) but this only runs the once.

    I’m looking for a way to use the

    ./ffmpeg -i input -vf "select=gt(scene\,0.4),scale=160:-1,tile,scale=600:-1" \
    
-frames:v 1 -qscale:v 3 preview.jpg

    command but using the fast seek method as it’s currently very slow when used with a remote file. I use PHP but I am aware that a C method exists by using av_seek_frame, I barely know C so I’m unable to implement this into a PHP script I’m writing. So hopefully, it is possible to do this directly with ffmpeg in the PHP system() function.

    Currently, I run seperate ffmpeg commands (with the -ss method) and then combine the screenshots together in PHP. However, with this method it will be refetching the metadata each time and a more optimized method would be to have it all happen in the same command line because I want to reduce the amount of requests made to the remote url so I can run more scripts in sequence with each other.

    Thank you for your help.
