Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;

ffmpeg make : *** No rule to make target 'distclean'. Stop
11 octobre 2016, par DjaveI’m installing ffmpeg using this guide https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu on a Digital Ocean droplet.
I’ve run all the commands down to

Android : Build a decoder library from Jpeg to MP4 video
9 juillet 2014, par Ilya_GazmanI am working on Android 2.2, and my goal is to covert a sequence of images to mp4 video, MPEG-4_Part_14, to be more exact.
The most reasonable solution would be using FFmpeg libraries, and compile them to Android using NDK. How ever I am looking for solution without NDK.
I do not expect from you to build this tool for me, or find some one else who did. I spent quit of time now searching for that, and it’s some thing that probably no1 one did yet.
So the only thing that I am asking, is help me find the specs so I be able to build the decoder by my self. I know that it’s not a trivial task(May be this is why no one did it yet), but I want to do it any way. So please just help me start it.

How to increase video encoding speed in ffmpeg ?
16 octobre 2017, par Ashutosh TiwariI am recording video clips and then joining all the clips in a final video.
Everything goes fine but the joining process takes too long.Tried to using some ffmpeg filters from here :
https://trac.ffmpeg.org/wiki/Encode/H.264And here is my ffmpeg command that I am using to increase the speed (which seems to be wrong) :
command = new String[]{"-y",
"-f",
"concat",
"-safe",
"0",
"-i",
"/storage/emulated/0/DCIM/my_file.txt",
"-c:v",
"-preset",
"fast",
"-crf",
"22",
"copy",
"-flags",
"+global_header",
"/storage/emulated/0/DCIM/SampleApp/" + videoOutputPath
};Please help ! Thanks much.
