La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

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 :

Android recording video with overlay view [way 1]
2 mars 2016, par t0mI am trying app in android which have functionality to capture video with overlay views. I tried two ways (1. and 2.).
1. Via SurfaceView and JavaCV with FFmpeg.
2. Via OpenCV and JavaCV with FFmpeg.
3. For API21+ maybe with MediaProjection.(Question is divided to two questions, due to stackoverflow length limit.)
ad 1. Via SurfaceView and JavaCV with FFmpeg :
