前言
菜谱编程，照着菜谱做，你也能实现我相同的效果。
条条大路通罗马，我的方法并不一定是最好的，只是个人一些技术总结，仅供参考
一、准备食材
1、livego下载【负责配置本地直播环境】
2、uniapp下载【负责手机端直播推流使用】
3、Anaconda下载【负责python Opencv包管理】
4、OBS Studio下载【负责推流直播的测试工作】【可选】
5、VLC media player下载【负责测试直播环境的拉流是否成功】【可选】
二、配置直播环境
1.下载：livego编译包 https://github.com/gwuhaolin/livego/releases
根据你的工作环境选择相应的，这里默认使用win环境
win版用法：
下载完成之后：
1、打开：livego.exe 程序
你会看到程序正在运行
time="2022-06-15T12:56:11 08:00" level=warning msg="open livego.yaml: The system cannot find the file specified."
time="2022-06-15T12:56:11 08:00" level=info msg="Using default config"
time="2022-06-15T12:56:11 08:00" level=info msg="\n _ _ ____ \n | | (_)_ _____ / ___| ___ \n | | | \\ \\ / / _ \\ | _ / _ \\ \n | |___| |\\ V / __/ |_| | (_) |\n |_____|_| \\_/ \\___|\\____|\\___/ \n version: master\n\t"
time="2022-06-15T12:56:11 08:00" level=info msg="HLS listen On :7002"
time="2022-06-15T12:56:11 08:00" level=info msg="HTTP-API listen On :8090"
time="2022-06-15T12:56:11 08:00" level=info msg="HLS server enable...."
time="2022-06-15T12:56:11 08:00" level=info msg="HTTP-FLV listen On :7001"
time="2022-06-15T12:56:11 08:00" level=info msg="RTMP Listen On :1935"
表示运行成功，参考说明文档2、打开浏览器，输入url （“http://localhost:8090/control/get?room=movie”）
你会看到{"status":200,"data":"rfBd56ti2SMtYvSgD5xAV0YU99zampta7Z7S575KLkIZ9PYk"}
表示环境已经运行成功了
1.测试直播环境是否有效
下载
OBS Studio下载【负责推流直播的测试工作】【可选】
VLC media player下载【负责测试直播环境的拉流是否成功】【可选】
随便一部.mp4视频
1、打开 OBS软件
2、打开设置页面输入推流url与key值(key值，也就是一开始打开浏览器的的值){"status":200,"data":"rfBd56ti2SMtYvSgD5xAV0YU99zampta7Z7S575KLkIZ9PYk"}
推流url：如果没有特殊需求可以直接输入：rtmp://localhost:1935/live/ 默认推流url地址
输入对应的值记得保存
3、选择mp4文件开始推流
表示推流已经成功
测试直播是否有效
打开VLC media player下载【负责测试直播环境的拉流是否成功】【可选】
输入拉流地址
到这里表示直播推拉流基本功能实现了
三.配置Anaconda环境（懂得可以直接跳过）
下载Anaconda下载【负责python Opencv包管理】注意* 下载Anaconda不是必须的，只是因为纯粹为了好管理python的包，Opencv才是这次做菜关键的目的
1.安装Anaconda完成之后，打开Anaconda Navigator (conda).exe
2.PyCharm 关联 Anaconda环境
打开 PyCharm
测试opencv是否成功（示例）：
import cv2 as cv
#读取图片
img = cv.imread('1.jpeg')
#暂示图片
cv.imshow('ceshi',img)
#关闭窗口
cv.waitKey(0)
cv.destroyAllWindows()
可以看到图片代表opencv有效
四.uniapp部分——写一个可以直播的app装手机上
uni-app写一个可以推流的app装在手机上下面是文档说明：https://uniapp.dcloud.io/api/media/live-player-context.html
uniapp部分：先创建一个首页，然后跳转到创建直播，然后再跳转到直播间进行推流。
而负责拉流的部分，则是使用下面部分的python代码，把拉流地址填上运行即可。
uniapp:手机app首页部分

五.python代码部分
import cv2 as cv
# 读取照片，转换成灰度图
def face_detect_img(img):
gray_img = cv.cvtColor(img, cv.COLOR_RGB2GRAY)
# 将级联算法加载到一个变量中
#每个人的路径不一样请根据自己的路径填写-----人脸识别
haar_face_cascade = cv.CascadeClassifier('E:/conda/envs/pycharm/Library/etc/haarcascades/haarcascade_frontalface_alt.xml')
faces = haar_face_cascade.detectMultiScale(gray_img, scaleFactor=1.1,minNeighbors=3)
# 在图像中画上矩形框和圆框
for (x, y, w, h) in faces:
print(x,y,w,h)
cv.rectangle(img, (x, y), (x w, y h), (156, 114, 32), 2)
cv.imshow("detect",img)
# 加载图片
#加载直播流
cap = cv.VideoCapture('rtmp://localhost:1935/live/movie')#如果你不想用手机也可以直接使用OBS也是可以的
# cap = cv.VideoCapture('1.mp4')
while True:
flag,frame=cap.read()
if not flag:
break
face_detect_img(frame)
if ord('q') == cv.waitKey(10):
break
cv.destroyAllWindows() # 释放内存
cap.release()
cv.CascadeClassifier('请填写自己的路径')
E:/conda/envs/pycharm/Library/etc/haarcascades/haarcascade_frontalface_alt.xml
仅供参考，我们主要是获取：haarcascade_frontalface_alt.xml 用户人脸识别使用
这是网上找的资料：
Opencv自带训练好的人脸检测模型，存储在sources/data/haarcascades文件夹和sources/data/lbpcascades文件夹下。其中几个.xml文件如下：
人脸检测器（默认）：haarcascade_frontalface_default.xml
人脸检测器（快速Harr）：haarcascade_frontalface_alt2.xml
人脸检测器（侧视）：haarcascade_profileface.xml
眼部检测器（左眼）：haarcascade_lefteye_2splits.xml
眼部检测器（右眼）：haarcascade_righteye_2splits.xml
嘴部检测器：haarcascade_mcs_mouth.xml
鼻子检测器：haarcascade_mcs_nose.xml
身体检测器：haarcascade_fullbody.xml
人脸检测器（快速LBP）：lbpcascade_frontalface.xml
这里先展示使用OBS推流的效果
opencv把直播流视频分割成一张张图片，然后进行识别
五.最终效果
总结
这是对于自己关于直播练习的小项目，其中走了很多弯路。写一篇关于自己对于整个过程的总结。
