Enregistrement vidéo ne fonctionne pas sur ubuntu14.04

Question

Je suis en train d'enregistrer mon ubuntu 14.04 machine..Here est ce que je l'ai fait .. echo "Installation Window Manager & VNC ..." apt-get install -qq -y xvfb >> install.log apt-get install -qq -y x11vnc >> install.log apt-get install -qq -y Fluxbox >> install.log chmod + x x11vnc & & mv x11vnc/usr/bin/ # Installez avconv + libx264 codec pour convertir flv en mp4 qui est jouable sur les navigateurs Web echo "Installation des utilitaires d'enregistrement d'écran VNC" easy_install vnc2flv 2> & 1 >> install.log apt-get install -qq -y c >> install.log apt-get install -qq -y libavcodec-extra-53 >> install.log [[$? -ne 0]] & & apt-get install -qq -y libavcodec-extra-54 >> install.log # ubuntu 14

NUM_EXECUTORS="1" 
SCREEN_RES="1440x1080x16" 

xvfb_vncstart() { 
    # dropping the vnc password into a text file for the vnc recording tool 
    local PASSWORD_FILE=/tmp/vnc-password.txt 
    if [ -f $PASSWORD_FILE ]; then 
    rm $PASSWORD_FILE 
    fi 
    echo "$VNC_PASSWORD" > $PASSWORD_FILE 
    export VNC_PASSWORD 

    echo "Starting $NUM_EXECUTORS X servers..." 
    export NUM_EXECUTORS 
    for i in $(seq 1 $NUM_EXECUTORS); do 
    echo "Launching X server $i..." 
    # Start the X frame buffer implementation 
    sudo -i -u ubuntu Xvfb :$i +extension GLX -screen 0 $SCREEN_RES -ac &> xvfb-$i.log & 

    # Sleep a little to give programs a chance to start 
    sleep 2 

    # Start the fluxbox window manager. 
    # We need a light window manager that allows maximizing windows 
    sudo -i -u ubuntu DISPLAY=:$i fluxbox &> fluxbox-$i.log & 

    # Sleep a little to give programs a chance to start 
    sleep 2 

    # Share the xsession over VNC 
    sudo -i -u ubuntu x11vnc -forever -display :$i -N -passwdfile /tmp/vnc-password.txt &> vnc-$i.log & 

    # Sleep a little to give programs a chance to start 
    sleep 2 
    done 
} 


But video recording doesn't work even when I try to run startx.

Answer 1

Le problème est résolu maintenant .. L'enregistrement est effectué dans le processus java ..
= new ProcessBuilder pb (screenRecorderProcessLocation, "-an", "-s", System.getenv ("SCREEN_RES"), "-f", "x11grab", "-i", "localhost:" + affichage, "-vcodec", "libx264" "-r", "24", screenVideoFile.getAbsolutePath()); La valeur SCREEN_RES n'a pas été trouvée dans la variable d'environnement qui a empêché l'avconv d'enregistrer. Après le codage en dur avec la résolution, l'enregistrement vidéo a commencé pour moi. La meilleure façon de vérifier est manuellement si l'extrait d'enregistrement est exécuté vérifier si son fonctionnement ou non .. Et puis la mise en œuvre .. J'ai eu de la chance après 20 jours sans savoir ce qui s'est mal passé! Salut tout le monde !! Bon apprentissage !!!
