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 (...) -
Keeping control of your media in your hands

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 (...)

FFMPEG read audio convenience function
7 mars 2016, par Phlox MidasIn Matlab, there’s a function called
audioread
that takes a file name as input and returns a vector of samples and the sample rate like this :[samples, sampleRate] = audioread(fileName);
I’ve been programming FFMPEG but finding it very low level. I have a file being read using a technique similiar to this. Is there any such equivalent C function in FFMPEG as there is in Matlab so I don’t have to fiddle with the low level stuff ? Or any library that can provide a nice API like this for FFMPEG (though I would just prefer this one function) ?

How to use hardware acceleration with ffmpeg
5 avril 2018, par ixSciI need to have ffmpeg decode my video(e.g. h264) using hardware acceleration. I’m using the usual way of decoding frames : read packet -> decode frame. And I’d like to have ffmpeg speed up decoding. So I’ve built it with
--enable-vaapi
and--enable-hwaccel=h264
. But I don’t really know what should I do next. I’ve tried to useavcodec_find_decoder_by_name("h264_vaapi")
but it returns nullptr.
Anyway, I might want to use others API and not just VA API. How one is supposed to speed up ffmpeg decoding ?P.S. I didn’t find any examples on Internet which uses ffmpeg with hwaccel.
