MediaSPIP Core : La Configuration
9 novembre 2010, parMediaSPIP Core fournit par défaut trois pages différentes de configuration (ces pages utilisent le plugin de configuration CFG pour fonctionner) : une page spécifique à la configuration générale du squelettes ; une page spécifique à la configuration de la page d’accueil du site ; une page spécifique à la configuration des secteurs ;
Il fournit également une page supplémentaire qui n’apparait que lorsque certains plugins sont activés permettant de contrôler l’affichage et les fonctionnalités spécifiques (...) -
Configuration spécifique d’Apache
4 février 2011, parModules spécifiques
Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

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.

using ffmpeg for development, libavutil/error environment not OK
26 février 2018, par luoyangheroI want to build a latest ffmpeg development library. I refered the docker script
’https://github.com/jrottenberg/ffmpeg/blob/master/docker-images/3.4/Dockerfile’,
and I changed the docker file to a shell file. Download all source files,
compile all dependency source and ffmpeg 3.4.1 source.
The following is my changed shell script.#!/bin/sh

Now I write a simple code, save as a 0_hello_world.c file.
#
#include "libavcodec/avcodec.h"
#include "libavformat/avformat.h"
#include
#include
#include
#include
#include
#include
#include
#include "libavutil/error.h"
int main(int argc, const char *argv[])
{
av_register_all();
int response = 0;
char *pchar;
// pchar = av_err2str(response);
return 0;
}#
Use the follow command for make, it’s OK.
#
gcc -g -Wall -o build/hello_world -lz 0_hello_world.c
-lavformat -lavcodec -lswscale
-I/opt/ffmpeg/include -L/opt/ffmpeg/lib#
But when I use the "av_err2str" function(uncomment this line) :
’pchar = av_err2str(response) ;’
compile show the following error :#
gcc -g -Wall -o build/hello_world -lz 0_hello_world.c
-lavformat -lavcodec -lswscale
-I/opt/ffmpeg/include -L/opt/ffmpeg/lib
0_hello_world.c: In function ‘main’:

char *pchar;

collect2: error: ld returned 1 exit status

make: *** [hello_world] Error 1#
As I know "av_register_all" use the "libavformat/avformat.h" header ; "av_err2str" use the "libavutil/error.h" header.
Both the two headers I have included, why "av_err2str" is not OK ?
I guess this is my environment not OK. How can I find the error ?
I have checked my LD_LIBRARY_PATH, it is OK.#

Demultiplex UDP live stream to multiple single live stream outputs using FFMPEG & FFSERVE
22 mars 2018, par tiras muturii have a problem with ffmpeg. i have an input live stream that has 8 inputs and i want to use ffmpeg to convert it from udp live steram to tcp livestream and then extract each of the 8 input stream differently.
i have been reading about the ffmpeg documentation at they havent provided a clear way of solving my problem.
am running
