FFmpeg: Performance de conversion pour WebM et nombre de CPU

Par david techer, dimanche 29 août 2010 à 16:52 :: Multiméda sous GNU/Linux

On dispose pour ce test

  1. d'une petite machine avec Processeur Intel Core 2 Quad Q8200
  2. d'une version de ffmpeg compilée avec WebM

Test normal

On lance dans un script shell le contenu 
begin_times=`date '+%s'`;
time /opt/multimedia-prod/bin/ffmpeg -y -i janadefi-daywith03.wmv -f webm -vcodec libvpx janadefi-daywith03.webm;
end_times=`date '+%s'`;duration_times=`expr $end_times - $begin_times`;
echo "Ecoulement approximatif de $duration_times secondes..."
On exécute le script. Pendant la converson, on lance depuis un autre shell

Hobbit-client 4.3 et Serveur Hobbit 4.2

Par david techer, samedi 28 août 2010 à 22:00 :: Mon réseau et compagnie...

A la maison, j'ai mon serveur Hobbit qui tourne sous 4.2. Sur gemini (une des machines clientes), je viens tout juste d'installer hobbit-client.

Malheureusement c'est un hobbit-client version 4.3 car gemini est une Ubuntu Lucid Lynx 10.04

Installlation du client

apt-get install hobbit-clientl hobbit-plugins
Lors de l'installation, il faudra préciser l'IP du serveur Hobbit

Ensuite, il faut modifier le fichier pour supprimer le sufixe davidgis.fr à  la ligne CLIENTHOSTNAME="gemini" au lieu de CLIENTHOSTNAME="gemini.davidgis.fr"

root@gemini:~# cat /etc/default/hobbit-client
# Configure the Hobbit client settings.

# You MUST set the list of Hobbit servers that this
# client reports to.
# It is good to use IP-adresses here instead of DNS
# names - DNS might not work if there's a problem.
# (Internally this will be translated to BBDISP and BBDISPLAYS
# variables in /var/run/hobbit/bbdisp-include.cfg)
#
# E.g. (a single Hobbit server)
#   HOBBITSERVERS="192.168.1.1"
# or (multiple servers)
#   HOBBITSERVERS="10.0.0.1 192.168.1.1"

HOBBITSERVERS="192.168.2.242"

# Hostname used by the client for its reports.
# Must match the name for this host in the Hobbit servers'
# bb-hosts file.

root@gemini:~# cat /etc/default/hobbit-client
# Configure the Hobbit client settings.

# You MUST set the list of Hobbit servers that this
# client reports to.
# It is good to use IP-adresses here instead of DNS
# names - DNS might not work if there's a problem.
# (Internally this will be translated to BBDISP and BBDISPLAYS
# variables in /var/run/hobbit/bbdisp-include.cfg)
#
# E.g. (a single Hobbit server)
#   HOBBITSERVERS="192.168.1.1"
# or (multiple servers)
#   HOBBITSERVERS="10.0.0.1 192.168.1.1"

HOBBITSERVERS="192.168.2.242"

# Hostname used by the client for its reports.
# Must match the name for this host in the Hobbit servers'
# bb-hosts file.

CLIENTHOSTNAME="gemini"

Configuration cà´té serveur

On ajoute la ligne suivante dans le fichier /etc/hobbit/bb-hosts 
melina-xen06:~# head -n35 /etc/hobbit/bb-hosts 
###############################################################################################
# $Id: bb-hosts 55 2010-08-28 18:19:20Z david $
###############################################################################################
# Master configuration file for Hobbit
#
# This file defines several things:
#
# 1) By adding hosts to this file, you define hosts that are monitored by Hobbit
# 2) By adding "page", "subpage", "group" definitions, you define the layout
#    of the Hobbit webpages, and how hosts are divided among the various webpages 
#    that Hobbit generates.
# 3) Several other definitions can be done for each host, see the bb-hosts(5)
#    man-page.
#
# You need to define at least the Hobbit server itself here.

#0.0.0.0        .default.       # NOPROPRED:+apt,+libs

Ce qui donnera donc ceci

Suppression du test pour apt

  1. Cà´té Client:

    Depuis gemini (client), il faut décommenter la ligne '#DISABLED' dans le fichier. Pour le coup, un petit sed interactif devrait suffire 
    root@gemini:~# cat /etc/hobbit/clientlaunch.d/apt.cfg
[apt]
	#DISABLED
	ENVFILE /etc/hobbit/hobbitclient.cfg
	CMD $HOBBITCLIENTHOME/ext/apt
	LOGFILE /var/log/hobbit/hobbitclient.log
	INTERVAL 5m
root@gemini:~# sed -i "s:#::g" /etc/hobbit/clientlaunch.d/apt.cfg
root@gemini:~# cat /etc/hobbit/clientlaunch.d/apt.cfg
[apt]
	DISABLED
	ENVFILE /etc/hobbit/hobbitclient.cfg
	CMD $HOBBITCLIENTHOME/ext/apt
	LOGFILE /var/log/hobbit/hobbitclient.log
	INTERVAL 5m

  2. Cà´té Serveur:

    On voit que le test est toujours actif 
    melina-xen06:~# /usr/lib/hobbit/server/bin/bb 127.0.0.1 "hobbitdboard test=apt fields=hostname"
gemini
    Il faut donc le dropper 
    TEST=apt;
/usr/lib/hobbit/server/bin/bb 127.0.0.1 "hobbitdboard test=$TEST fields=hostname"| \
 while read H;
 do
    /usr/lib/hobbit/client/bin/bb 127.0.0.1 "drop $H $TEST";
done
    On vérifie 
    melina-xen06:~# /usr/lib/hobbit/server/bin/bb 127.0.0.1 "hobbitdboard test=apt fields=hostname"

SMPlayer - Activer le son

Par david techer, samedi 28 août 2010 à 13:05 :: Multiméda sous GNU/Linux

Depuis que j'ai installé SMPlayer lors de mes lectures de films, j'ai bien la vidéo mais pas le son ....En fait il suffit de remanier le fichier de configuration de smplayer

Comme mon utilisateur c'est david, il suffit donc de modifier le fichier ~/.config/smplayer/smplayer.ini en remplaçant la valeur du paramètre driver\audio_output

  1. On remplace la ligne 
    driver\audio_output=null
  2. par la ligne 
    driver\audio_output=alsa
