五、结语
一、前言
看见b站的向军大叔用electron制作了一个桌面摄像头软件
但是，我不怎么熟悉前端，自己就用pyside6简单制作一个
二、桌面摄像头软件
2.1、下载项目
软件下载地址：（下载后，双击即可运行——60MB左右）
https://wwm.lanzout.com/ibIEL1q0xt8d
密码:eg34
工程文件下载地址：
camera-python.zip - 蓝奏云
启动项目：
# 下载包 pip install -r requirements.txt # 运行项目 python main.py
2.2、功能介绍
启动后，会自动打开默认摄像头
基础操作
左键长按：拖拽移动
滚轮上下滑动：放大和缩小摄像头画面
右键设置操作
选择边框颜色（rgb格式）
选择摄像头（自由切换）
窗口变形（正方形窗口和圆形窗口的切换）
隐藏
退出
系统托盘（可右键选择隐藏或出现，以及退出）
三、打包工具（nuitka）
Python——Windows使用Nuitka2.0打包（保姆级教程）-CSDN博客
我的打包命令：
nuitka --mingw64 --show-progress --standalone --disable-console --enable-plugin=pyside6 --plugin-enable=numpy --onefile --remove-output --windows-icon-from-ico=logo.ico camera.py
四、项目文件复制（我全部合到一个文件里面了）

五、结语
- 如果你有任何问题，欢迎在评论区留言，我会尽快回复。
- 很久没有碰pyside6，而且学的很浅显，写了屎山代码
- 目前只能保证功能实现，里面还有一些小bug
- 但是不影响正常使用，就这样吧~
PS：其实我只是想自己拿来用用
