Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...) -
Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.
Version mono serveur
La version mono serveur consiste à n’utiliser qu’une (...) -

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}'

Extract Video Frames In Python
28 février 2024, par TheNoneI want to extract video frames and save them as image.



import os, sys
from PIL import Image

a, b, c = os.popen3("ffmpeg -i test.avi")
out = c.read()
dp = out.index("Duration: ")
duration = out[dp+10:dp+out[dp:].index(",")]
hh, mm, ss = map(float, duration.split(":"))
total = (hh*60 + mm)*60 + ss
for i in xrange(9):
 t = (i + 1) * total / 10
 os.system("ffmpeg -i test.avi -ss %0.3fs frame%i.png" % (t, i))



But I have this error :

Motion estimation methods:

Note, the names of encoders and decoders dont always match, so there are
several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported for example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats its even
worse



What is wrong in my code ? Thanks in advance
