flameshot截屏很方便,支持打马赛克,写入文字等。

~$ sudo apt-get install flameshot

1.3 X11配置

Debian buster 默认使用Wayland。Vokoscreen不支持Wayland, 需要切回Xorg,修改 /etc/gdm3/daemon.conf 设置 WaylandEnable=false。

# GDM configuration storage
#
# See /usr/share/gdm/gdm.schemas for a list of available options.

[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false

Wayland is a communication protocol that specifies the communication between a display server and its clients. A display server using the Wayland protocol is called a Wayland compositor, because it additionally performs the task of a compositing window manager.

1.4 Resolution

现在屏幕分辨率都比较高,生成视频占用空间大,可以用 ffmpeg 进行任意调整。

例如,将 1600x900 录屏文件调整为 640x480:

~$ ffmpeg -i vokoscreen.orig.mp4 -vf scale=640:360 -hide_banner vokoscreen.mp4
