Python——桌面摄像头软件（附源码+打包）-编程知识

一、前言

二、桌面摄像头软件

2.1、下载项目

2.2、功能介绍

三、打包工具（nuitka）

四、项目文件复制（我全部合到一个文件里面了）

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）
