Python——桌面攝像頭軟件（附源碼+打包）

一、前言

二、桌面攝像頭軟件

2.1、下載項目

2.2、功能介紹

三、打包工具（nuitka）

?四、項目文件復制（我全部合到一個文件里面了）

五、結語

一、前言

看見b站的向軍大叔用electron制作了一個桌面攝像頭軟件

但是，我不怎么熟悉前端，自己就用pyside6簡單制作一個

二、桌面攝像頭軟件

2.1、下載項目

軟件下載地址：（下載后，雙擊即可運行——60MB左右）

https://wwm.lanzout.com/ibIEL1q0xt8d
密碼:eg34

工程文件下載地址：

camera-python.zip - 藍奏云

啟動項目：
# 下載包
pip install -r requirements.txt# 運行項目
python main.py

2.2、功能介紹

啟動后，會自動打開默認攝像頭

基礎操作

左鍵長按：拖拽移動

滾輪上下滑動：放大和縮小攝像頭畫面

右鍵設置操作

選擇邊框顏色（rgb格式）

選擇攝像頭（自由切換）

窗口變形（正方形窗口和圓形窗口的切換）

隱藏

退出

系統托盤（可右鍵選擇隱藏或出現，以及退出）

三、打包工具（nuitka）

?Python——Windows使用Nuitka2.0打包（保姆級教程）-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、項目文件復制（我全部合到一個文件里面了）
