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 ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...) -
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 (...) -

Revision 1092140379 : No longer use use_lastframe_partitioning speed feature The speedup in rd_pick_p
6 septembre 2014, par Yunqing WangChanged Paths :
Modify /vp9/encoder/vp9_speed_features.c
No longer use use_lastframe_partitioning speed featureThe speedup in rd_pick_partition() function makes it possible
to drop use_lastframe_partitioning feature. By doing that, we
achieve good PSNR gain with small speed loss. Also, this makes
encoding loop less complicated. The code cleanup patch will
follow.Borg tests showed :
1. At speed 2,
stdhd set : 0.201% PSNR gain, 0.133% SSIM gain ;
derf set : 0.262% PSNR gain, 0.276% SSIM gain.
2. At speed 3,
stdhd set : 0.139% PSNR gain, 0.109% SSIM gain ;
derf set : 0.447% PSNR gain, 0.442% SSIM gain.The average speed loss over selected test clips is within 1%
with the worst case of 4%.Change-Id : Icfd2ded7869372b585a6972855d933b3d0280d90

Playing RDT (Real Data Transport) through FFmpeg without SDP file
24 février 2021, par William SeemannI'm doing some research into how Roku delivers their private listening stream. I believe the RTSP stream is delivered via RDT and I'm able to view the packets in Wireshark. I can't play the stream using FFmpeg despite it supporting RDT/RTSP because a SDP file is required. Is it possible to generate this SDP file or play the stream without one ?
