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 (...) -

ffmpeg encode video produce incorrect mediainfo encoding settings
25 août 2021, par FoongI've been trying to do batch encode videos to H265 format. I am using media-autobuild_suite to build ffmpeg and have already updating ffmpeg to the latest version.

However, the Writing library and Encoding settings output is incorrect. Before update ffmpeg doesn't have this issue. I wonder what have been missing that causing this issue.

I have tried with simplest ffmpeg from official wedsite and encoding cli but the output still same.


ffmpeg -i "input.mkv" -c:v libx265 "output.mkv"


Update :
Tried converting video with FFmpeg 4.4 "Rao" from https://www.ffmpeg.org/ working fine. But compiled ffmpeg from media-autobuild_suite, tried with light build and full build, Writing library and Encoding settings output still incorrect.

ffmpeg Transcoding Stops After Few Seconds [migrated]
15 avril 2018, par Salem FI’m trying to do this over week now with no success,
What’s I’m trying to do is transcoding video from live streaming source and downscale it with FFmpeg, but every time I start transcoding it broadcasting for 11 sec and stop.The last command I tried :
ffmpeg -re -i 'http://source.com/1034.ts' -preset ultrafast http://localhost:2052/feed1.ffmI tried to download the .ts file with IDM and it finish downloading the file on the exact 12 Sec that FFmpeg stop trans coding on it.
Does that means that FFmpeg download that file as one segment and not continued reading the source video As what video players does usually. By the way, I tried with source with VLC player and it didn’t stop playing the the same source video.
I decided to pass FFmpeg command via FFserver config file
ffserver.confLaunch ffmpeg -i 'http://source.com/1.ts' -copyinkf -codec copyThe stream works fine for a while but after testing couple sources I notice it’s struggle to trans-coding HD videos.
I guess the issue with my VPS KVM server being very limited CPU and RAM ( 128MB only) ! Since I tried using
ultrafastpreset but din’t solve the issue, another thing, I notice when I enableAVOptionVideo crfsetting onffserver.conftrans-coding runs bit smoothly without frame-rate dropping.
Las my server usesXeon L5520CPU which is outdated CPU specially I gout 1/4 power of V single core (if they count HT it will be 1/8 of the real core) : (# vlc -I dummy 'https://source.com/1034.ts' --sout '#standard{access=http,mux=flv,dst=localhost:2052}'

ffmpeg transcoding stop after few seconds
9 avril 2018, par Salem FHi i’m trying to do this over week now with no success ,
What’s i’m trying to do is transcoding video from live streaming source and downscale it with FFmpeg , but every time I start transcoding it broadcasting fro 11 Sec and stop . here last command I triedffmpeg -re -i 'http://source.com/1034.ts' -preset ultrafast http://localhost:2052/feed1.ffmI tried to download the .ts file with IDM and it finish downloading the file on the exact 12 Sec that FFmpeg stop trans coding on it .
does that means that FFmpeg download that file as one segment and not continued reading the source video As what video players does usually . BTW I tried with source with VLC player and it didn’t stop playing the the same source video .
Edit :- I decide to pass FFmpeg command via FFserver config file
ffserver.confLaunch ffmpeg -i 'http://source.com/1.ts' -copyinkf -codec copyThe stream works fine for a while but after testing couple sources I notice it’s struggle to trans-coding HD videos .
I guess the issue with my VPS KVM server being very limited CPU and RAM ( 128MB only ) ! Since I tried using
ultrafastpreset but din’t solve the issue , another thing , I notice when I enableAVOptionVideo crfsetting onffserver.conftrans-coding runs bit smoothly without frame-rate dropping .
Las my server usesXeon L5520CPU which is outdated CPU specially I gout 1/4 power of V single core (if they count HT it will be 1/8 of the real core ) :(Edit 2 :-
