Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -
MediaSPIP 0.1 Beta version
25 avril 2011, parMediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
The zip file provided here only contains the sources of MediaSPIP in its standalone version.
To get a working installation, you must manually install all-software dependencies on the server.
If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...) -

Ffmpeg avs to avi lossless conversion
21 février 2016, par PiotrHow to convert avs (Avisynth file) to avi without loss of quality ?
Firstly, I’m changing avs to 264 :
ffmpeg -i "Source.avs" -c:v libx264 -preset veryslow -crf 24 "Output.264"
Secondly, I’m trying to convert 264 to avi :
ffmpeg -i "input.264" "output.avi"
Final avi should have almost 200MB, but has only 2MB. 264 file has almost 150MB, so it should be good. I think that I should use some codec in second command, but I don’t know which. I’m trying to change this for a few days, but without effect.
Or maybe there is a way to lossless conversion without 264, only avs to avi ?
Thank you for your help.
Edit :
Thank you for answers. Unfortunatelly, both methods fail.
First gives me a video, which is blurry and I can’t see anything on it.Output :
