Les tâches Cron régulières de la ferme
1er décembre 2010, parLa 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 (...) -

How to batch generate EDL (edit decision list) files for a folder of videos with different run times
22 janvier, par DnKHow to batch generate EDL (edit decision list) files for a folder of videos with different run times ? I need to skip exact amount of seconds from the start and another amount of seconds from the end. All the videos have different runtimes I can make EDL files for skipping the intro but need a way to read the video runtime and skip the last 60 or 90 seconds.


This is the format for the EDL I am using with kodi


0:00:00 0:01:20. 3



So if the video is 40 mins 30 seconds the EDL generated skipping 80 seconds from the start and 90 seconds from the end should be


0:00:00 0:01:20. 3
0:39:00 0:40:30. 3

Is ffmpeg running in CPU or GPU ?

Step 2 : CPU vs GPU
that if the CPU % is more than 90 then the app is running in CPU.
While configuring ffmpeg, I enabled opencl. ffmpeg configurations are,

ffmpeg -i /home/M.mp4 -c:v h264 -preset:v faster /home/out.avi
the CPU% has been more than 90 (375%).
In case of ImageMagick, if I enable opencl while configuring, then the app will run in GPU, i.e., the CPU% will be less than 90. I noticed that.
But in case of ffmpeg, it is GPU accelerated one. Then, Why the CPU% is more than 90% ? Is the ffmpeg running in CPU or GPU ? If it is not, how can I make it to run in GPU ?
