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 (...) -
Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)
Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...) -

How can I use ffmpeg x11 capture in C++ code
12 juin 2015, par Özüm SafaoğluI want to grab x11 desktop in linux using ffmpeg, hoping it would give a fast output. However, I would like to do it within C++ code. I suppose it is possible to output it to stdout in the command line with
ffmpeg
command, however if possible i would prefer reading from memory buffer directly. Is there a way I can do this ? -

FFMPEG : Compilation error for custom code
13 février 2014, par samI have a video decoder integrated in FFMPEG. All the code that i have currently integrated is pure C-code. For performance purposes, i have to integrate the corresponding SSE code into the FFMPEG's libavcodec.
So i followed the same steps as i did while integrating the pure c code. While configuring i used the following command :
./configure --enable-sse --disable-yasm
I have disabled yasm as i dont have one installed, if needed i can install it, but for c code integration, i had not installed it.
After configuring, i give the command
make
, but i get all errors in my SSE code. So my first question is :-> Does giving —enable-sse ensures that the sse code will get compiled or i need to do something extra ? (Note : my processor supports upto sse 4.2 and the code i want to integrate is also in SSE4.2)
Next, inorder to resolve this what i did was, i opened the
config.mak
file, and found all gcc commands and i appended them with a -msse4.2 option (this option i use to compile standalone SSE code that is, compiling code without integrating it with FFMPEG).After modifying the
config.mak
(which i think i shouldn't, because it is auto-generated on ./configure command), although i'm not getting any error in SSE code, but i get errors likeundefined variable ...
anderror:No previous prototype
for all the old C code which is already a part of the code( although in the source file i have included the required headers).So my second question is, I have manually modified config.mak file is it ok to do so ? If so, then how do i resolve the above issue ?
Any help regarding this issue will be really helpful to me. Moreover there is no info on net available on compiling the FFMPEG code with SSE (except for using —enable-sse option while configuring, which i think is not working for me).
Thanks in advance.
