1、下载好nginx 和 ffmpeg之后直接解压到想保存的文件夹中
2、配置环境变量 ~~~~(此处交给度娘)
启动 nginx:
方法1、直接双击 nginx.exe,双击后一个黑色的弹窗一闪而过。
方法2、打开 cmd 命令窗口,切换到 nginx 解压目录下,输入命令 nginx.exe 或者 start nginx ,回车。
方法1、直接在浏览器地址栏输入网址 http://127.0.0.1:80 或者 http://localhost:80,回车,然后页面会告诉你欢迎使用nginx。
方法2、哈哈,就用方法1吧~
nginx 的配置文件是 conf 目录下的 nginx.conf,默认配置的 nginx 监听的端口为 80,如果 80 端口被占用可以修改为未被占用的端口即可,也因此 chrome 浏览器未显示端口。
检查 80 端口是否被占用的命令是:netstat -ano | findstr 0.0.0.0:80 或 netstat -ano | findstr “80”,如果打印出了一下内容则说明 80 端口被占用:
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 6220
当我们修改了 nginx 的配置文件 nginx.conf 时,不需要关闭 nginx 后重新启动 nginx,只需要执行命令nginx -s reload即可让改动生效
默认的 nginx.conf 文件并没有配置 RTMP 服务器,需要我们手动添加配置。具体步骤为:在 conf 目录中,复制粘贴 nginx.conf 文件并将其重名为 nginx-win.conf,修改其内容为:
#user nobody;
# multiple workers works !
worker_processes 2;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

worker_connections 8192;
# max value 32768, nginx recycling connections+registry optimization =
# this.value * 20 = max concurrent connections currently tested with one worker

这里监听端口未改动,仍然为 80,重点添加了 RTMP 服务器的相关配置,以搭建 RTMP 服务器,rtmp 协议的默认端口号是 1935。具体的配置详解请参考:菜鸟教程 - Nginx 配置详解
按住 windows 键 +R,输入 cmd,进入 cmd 命令窗口,进入 nginx 目录:cd (你的nginx目录),然后启动 nginx rtmp 服务器:
nginx.exe -c conf\nginx-win.conf
使用其他版本nginx可能会出现以下错误:
nginx: [emerg] unknown directive "rtmp" in E:\technology\nginx-1.17.9/conf\nginx-win.conf:19
这时需要下载源码编译时加入rtmp模块(俺也不会,看人家说的~)
或者更换为带 rtmp 模块的 nginx 版本,如 nginx 1.7.11.3 Gryphon(下载链接在本文开头。)
nginx启动成功之后就可以使用ffmpeg推流了。加油我们离成功又近了一步。
直接使用 ffmpeg 推流
ffmpeg.exe -re -i (你的视频文件 如 test.mp4)-f flv rtmp://127.0.0.1:1935/(你想加的路径,不加也可)
使用python,可以将接受的视频流处理后转发
#此处换为你自己的地址
rtmp_url = 'rtsp://127.0.0.1:1935/mv'
cap = cv2.VideoCapture((你的摄像头视频流地址))
fps = int(cap.get(cv2.CAP_PROP_FPS))
width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH))
height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT))
command = ['ffmpeg',
'-y',
'-f', 'rawvideo',
'-vcodec', 'rawvideo',
'-pix_fmt', 'bgr24',
'-s', "{}x{}".format(width, height),
'-r', str(fps),
'-i', '-',
'-c:v', 'libx264',
'-pix_fmt', 'yuv420p',
'-preset', 'ultrafast',
'-f', 'flv',
rtmp_url]
p = sp.Popen(command, stdin=sp.PIPE)
while (cap.isOpened()):
ret, frame = cap.read()
if not ret:
print("Opening camera is failed")
break
frame = 你的图像处理的函数(frame)
p.stdin.write(frame.tostring())
import cv2
cap = cv2.VideoCapture("rtsp://127.0.0.1:1935/mv")
while (cap.isOpened()):
ret, frame = cap.read()
if not ret:
print("Opening camera is failed")
break
cv2.imshow('起个名字',frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
当然,如果这几行代码你也不愿意写的话~我只能教你一点别的办法了
迅雷影音 推荐
下载地址:算了自己找吧~
食用方法:打开之后在中间的 框框中输入rtsp推流的地址就ok了
VLC media player
下载地址:https://www.videolan.org/vlc/index.html
运行之后选择媒体----网络串流----网络----填写地址(刚刚rtsp推流的地址)----选择播放
