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 (...) -

Evolution #3962 : Générer des JPEG progressifs
18 juin 2017, par Michel BystranowskiMmm, ça a l’air un peu plus compliqué qu’au premier abord effectivement. J’ai trouvé cet article qui compare le taux de compression et recommande de ne le faire que pour les fichiers de plus de 10k, sous peine d’obtenir des fichiers plus gros (https://yuiblog.com/blog/2008/12/05/imageopt-4/). Du coup il faudrait s’arranger pour ne cibler que les gros JPEGs.
Par côté compatibilité des navigateurs ça semble ok pour tous les navigateurs récents (https://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28graphics%29#JPEG_support).

avcodec : Remove libaacplus
24 janvier 2016, par Timothy Guavcodec : Remove libaacplus
TODO : bump minor
It’s inferior in quality to fdk-aac and has an arguably more problematic
license.As early as 2012, a HydrogenAudio user reported :
> It has however one huge advantage : much better quality at low bitrates than
> faac and libaacplus.I myself have made a few spectrograms for a comparison of the two
encoders as well. The FDK output is consistently better than the
libaacplus one, in all bitrates I tested.libaacplus license is 3GPP + LGPLv2. 3GPP copyright notice is completely
proprietory, as follows :> No part may be reproduced except as authorized by written permission.

Is there any way to edit just the metadata of an AVI file, like mkvpropedit does with MKV files ?
20 juillet 2016, par hmj6jmhI am trying to swap the order of 2 audio tracks of an AVI file using
ffmpeg
.ffmpeg -i "infile.avi" -map 0:0 -map 0:2 -map 0:1 -c copy "outfile.avi"
This works but the file is being re-encoded, not copied. It takes much longer than a straight copy to finish and the resulting file is larger than the original.
Is there any way to edit just the metadata of an AVI file, like mkvpropedit does with MKV files ? Command line tool preferred.
