| Byzanz č un'utility da riga di comando che permette di registrare .gif di ciņ che stiamo facendo, possiamo registrare una finestra, un'area o tutto lo schermo. Per installare: CODICE sudo add-apt-repository -y ppa:fossfreedom/byzanz
sudo apt-get update
sudo apt-get install -y byzanz Parametri di chiamata: CODICE Application Options:
-a, --audio
Record audio from the default input device. This only works if
the output format supports it and will otherwise cause an error.
-c, --cursor
Record mouse cursor
-d, --duration=SECS
Duration of animation (default: 10 seconds)
--delay=SECS
Delay before start (default: 1 second)
--display=DISPLAY
X display to use
-h, --height=PIXEL
Height of recording rectangle
-v, --verbose
Be verbos
-w, --width=PIXEL
Width of recording rectangle
-x, --x=PIXEL
X coordinate of rectangle to record
-y, --y=PIXEL
Y coordinate of rectangle to record Esempio di chiamata: CODICE byzanz-record --duration=15 --x=400 --y=400 --width=800 --height=600 output.gif Il problema di byzanz, come si puņ ben capire, č che come parametri di posizione vuole i pixel e le dimensioni e questo puņ essere un problema, ecco quindi due script che fanno al caso nostro (presi da askubuntu: http://askubuntu.com/questions/107726/how-...of-a-screencast) Per registrare una finestra: CODICE #!/bin/bash
# Delay before starting
DELAY=10
# Sound notification to let one know when recording is about to start (and ends)
beep() {
paplay /usr/share/sounds/KDE-Im-Irc-Event.ogg &
}
# Duration and output file
if [ $# -gt 0 ]; then
D="--duration=$@"
else
echo Default recording duration 10s to /tmp/recorded.gif
D="--duration=10 /tmp/recorded.gif"
fi
XWININFO=$(xwininfo)
read X < <(awk -F: '/Absolute upper-left X/{print $2}' <<< "$XWININFO")
read Y < <(awk -F: '/Absolute upper-left Y/{print $2}' <<< "$XWININFO")
read W < <(awk -F: '/Width/{print $2}' <<< "$XWININFO")
read H < <(awk -F: '/Height/{print $2}' <<< "$XWININFO")
echo Delaying $DELAY seconds. After that, byzanz will start
for (( i=$DELAY; i>0; --i )) ; do
echo $i
sleep 1
done
beep
byzanz-record --verbose --delay=0 --x=$X --y=$Y --width=$W --height=$H $D
beep Registrare con gui: CODICE #!/bin/bash
