Wayland - 腾讯会议屏幕共享解决方案

组会的时候尝试投屏却只能看到我的鼠标指针，最后演变为使用健硕手机拍屏方案，好不雅观。经过一翻搜索找到一个比较优雅（Yet 扭曲）的解决方案，因此简单记录一下。

安装

安装 Xwayland-standalone (基本上就是配置了 libdecor 支持的 xorg-xwayland) 和 openbox

脚本

#!/usr/bin/python3
# Original script: https://gitlab.gnome.org/-/snippets/19
# Sharing wayland screen/window with portal + pipewire to X programs
# Modifications:
# 1. Add --show-cursor option
# 2. Fix the bug that the script won't exit after the window is closed

# Known bugs:
# 1. Screencasting monitors without top bar may not work smoothly in GNOME
#    (Seems that this has been resolved in GNOME 43)
#    (Contents of xvimagesink window may not updated when not focused
#     and glitches may appear when sharing with cursor.
#     One workaround is to not maximize the xvimagesink window
#     and select "Always on top" in mutter window manager)
# 2. Sharing window in GNOME will bring a large black border around window
#    (And I don't know how to fix this: maybe gstreamer pipeline should know more about the window size?
#     and the sink should self-resize dynamically to fit the window size?)
