参考：

• http://askubuntu.com/questions/107726/how-to-create-animated-gif-images-of-a-screencast

 

1、软件安装

$ sudo apt-get install byzanz

 

2、脚本下载

1）byzanz-record-window.sh

#!/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

 

2）byzanz-record-region.sh

#!/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



# xrectsel from https://github.com/lolilolicon/xrectsel

ARGUMENTS=$(xrectsel "--x=%x --y=%y --width=%w --height=%h") || exit -1



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 ${ARGUMENTS} $D

beep

 

3）byzanz-record-window-gui.sh

#!/bin/bash

# NAME:     GIFRecord 0.1

# DESCRIPTION:  A script to record GIF screencasts.

# LICENSE:  GNU GPL v3 (http://www.gnu.org/licenses/gpl.html)

# DEPENDENCIES:   byzanz,gdialog,notify-send (install via sudo add-apt-repository ppa:fossfreedom/byzanz; 
#                 sudo apt-get update && sudo apt-get install byzanz gdialog notify-osd)



# Time and date

TIME=$(date +"%Y-%m-%d_%H%M%S")



# Delay before starting

DELAY=10



# Standard screencast folder

FOLDER="$HOME/Pictures"



# Default recording duration

DEFDUR=10



# Sound notification to let one know when recording is about to start (and ends)

beep() {

    paplay /usr/share/sounds/freedesktop/stereo/message-new-instant.oga &

}



# Custom recording duration as set by user

USERDUR=$(gdialog --title "Duration?" --inputbox "Please enter the screencast duration in seconds" 200 100 2>&1)



# Duration and output file

if [ $USERDUR -gt 0 ]; then

    D=$USERDUR

else

    D=$DEFDUR

fi



# Window geometry

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")



# Notify the user of recording time and delay

notify-send "GIFRecorder" "Recording duration set to $D seconds. Recording will start in $DELAY seconds."



#Actual recording

sleep $DELAY

beep

byzanz-record -c --verbose --delay=0 --duration=$D --x=$X --y=$Y --width=$W --height=$H "$FOLDER/GIFrecord_$TIME.gif"

beep



# Notify the user of end of recording.

notify-send "GIFRecorder" "Screencast saved to $FOLDER/GIFrecord_$TIME.gif"

 

3、安装脚本依赖的程序

1）克隆代码

• https://github.com/lolilolicon/xrectsel.git

2）编译安装

./bootstrap  # required if ./configure is not present

./configure --prefix=/usr

make

$ sudo make instal

 

注：在执行

./bootstrap

时若出现以下错误

./bootstrap: line 1: autoreconf: command not found

解决办法是：

$ sudo apt-get install autoconf

 

4、配置脚本执行权限

$ sudo chmod 755 ./byzanz-record-region.sh 

$ sudo chmod 755 ./byzanz-record-window.sh 

$ sudo chmod 755 ./byzanz-record-window-gui.sh

 

5、使用方法

./byzanz-record-region.sh duration-seconds save-file-name // 使用鼠标选择要记录的区域

./byzanz-record-window.sh duration-seconds save-file-name // 默认选择整个屏幕

 

6、试用效果如下

./byzanz-record-region.sh

 

7、为方便以后使用可以将其添加至环境变量中

Enjoy it.
