La file d’attente de SPIPmotion
28 novembre 2010, parUne file d’attente stockée dans la base de donnée
Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...) -
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 (...) -

Raspberry crosscompilation in Eclipse
27 juin 2018, par gogoerI want to compile an application for Raspberry in Eclipse (in windows). I installed SysGCC, configured Eclipse for crosscompiling. And if I create something like "Hello world" - everything is ok. Eclipse creates binaries which wonderfully works on Raspberry.
But i need use FFMPEG libraries in my application . Here the minimal code of application :#include <libavcodec></libavcodec>avcodec.h>
#include <libavformat></libavformat>avformat.h>
#include <libswscale></libswscale>swscale.h>
int main(void) {
av_register_all();
return EXIT_SUCCESS;
}I added libraries in project config. Project compiles good, but linker gives a lot of errors :
C:\SysGCC\Raspberry\arm-linux-gnueabihf\sysroot\usr\local\lib\libavcodec.a(aaccoder.o): In function `quantize_and_encode_band_cost_template':

collect2.exe: error: ld returned 1 exit status
make: *** [ffmpeg] Error 1
02:21:24 Build Finished (took 8s.394ms)SOLVED :
i used next command :
arm-linux-gnueabihf-gcc -L"C:\SysGCC\Raspberry\arm-linux-gnueabihf\sysroot\usr\local\lib" -L"C:\SysGCC\Raspberry\arm-linux-gnueabihf\lib" -o "ffmpeg" ./src/ffmpeg.o -lc -lm -lpthread -lavformat -lavcodec -lswscale -lavutil -lavfilter -lavdevice -lswresample -lpostproc -ldl -lx264 -lgcc -lz
where -lc -lm -lpthread -lavformat -lavcodec -lswscale -lavutil -lavfilter -lavdevice -lswresample -lpostproc -ldl -lx264 -lgcc -lz are libraries linker needs (maybe not all of them).
please note that order is important.
