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 (...) -

ffmpeg converted x264 video shows sharply reduced color saturation
3 novembre 2015, par xaphodI’m an ffmpeg noob. I did spend 30 mins googling stackoverflow though, and didn’t find an answer.
My designer made me some videos, of animated drawings. They’re great, but huge. So I tried passing them through ffmpeg. They get 10x smaller and don’t look pixelated — great ! — but the color is greatly reduced. What’s bright red/pink in the original becomes washed out ashey-grey-red in the output, when I view it on my macbook, or in the app it’s going into (iOS — ie. on an iPhone 5S you can see the missing color). How can I get the color to stay the same(ish) ?
ffmpeg -i original.mp4
shows me this :

Evolution #3587 (Nouveau) : Intégrer le plugin upload HTML5 dans SPIP
9 novembre 2015, par realet RealETJ’utilise avec bonheur depuis mai 2015 ce plugin : http://contrib.spip.net/Formulaire-d-upload-en-html5
Il permet :
- de glisser/lâcher des fichiers pour les téléverser sur le serveur
- il permet de le faire pour plusieurs fichiers à la fois !
- un clic lance la boite de dialogue de sélection de fichiers classique (mais avec la possibilité de choisir plusieurs fichiers)
- le téléversement est animé avec une barre de progression (et si c’est une image, une version miniature)
Bref, c’est une série d’amélioration visuelles et fonctionnelles qui sont :
- utilises
- ergonomiques
- conviviales
- immédiatement visible
- et intéressant à annoncer comme évolution de SPIP
De plus, sous le capot, ça utilise les mécanismes natifs de SPIP pour l’upload, donc, la sécurité native de SPIP.

ffmpeg overlay video with transparent background
27 octobre 2015, par endryhaI have 2 videos : background (mp4) and overlay (mov), overlay has transparent background. I am trying to put video with transparent background as overlay on top of background video. But unfortunately overlay completely cover background video with black background instead of transparency.
I am using following command :Here is the full output for the command :
ffmpeg -y -i rec_20151027_123445.mp4 -vf "[in]format=rgba[ina];movie=overlay_1920x1080_1.mov[o];[ina][o]overlay=0:0" -vcodec qtrle converted.mov
