安装

sudo apt-get install byzanz

使用

录制15秒,x,y区域左上角坐标,out.gif 输出的文件 bash byzanz-record --duration=15 --x=200 --y=300 --width=700 --height=400 out.gif

要怎么才能自己选定区域呢,有高手已经写成脚本了,只要执行以下脚本便可以自己手动选择区域进行录制,输出文件在/tmp里,可以修改--duration=需要的录制时间(ps要有bash的执行权限)

#!/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/FFcast2/blob/master/xrectsel.c
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

下面这个脚本是选择窗口进行录制,方法同上,直接运行

#!/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
