大疆无人机rtmp推流直播到电脑（Windows版本已成功）一、所需资源二、安装三、ffmpeg推流四、无人机rtmp推流五、Python获取无人机实时视频

一、所需资源

1、nginx的Gryphon版本，它内部已经集成了rtmp的推流编译(nginx-Gryphon) 2、服务器状态检查程序stat.xsl（nginx-rtmp-module） 3、ffmpeg（ffmpeg） 4、VLC（VLC）

二、安装

1、将下载好的nginx 1.7.11.3 Gryphon解压修改文件名为nginx-1.7.11.3-Gryphon，绝对路径中不能有中文，必须全为英文！ 2、在根目录中的conf文件夹中，若有nginx.conf文件，直接进入修改；若无，则创建一个。 3、在nginx文件中，将以下内容粘贴。

#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; events { worker_connections 8192; # max value 32768, nginx recycling connections+registry optimization = # this.value * 20 = max concurrent connections currently tested with one worker # C1000K should be possible depending there is enough ram/cpu power # multi_accept on; } rtmp { server { listen 1935; chunk_size 4000; application live { live on; } } } http { #include /nginx/conf/naxsi_core.rules; include mime.types; default_type application/octet-stream; #log_format main '$remote_addr:$remote_port - $remote_user [$time_local] "$request" ' # '$status $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log logs/access.log main; # # loadbalancing PHP # upstream myLoadBalancer { # server 127.0.0.1:9001 weight=1 fail_timeout=5; # server 127.0.0.1:9002 weight=1 fail_timeout=5; # server 127.0.0.1:9003 weight=1 fail_timeout=5; # server 127.0.0.1:9004 weight=1 fail_timeout=5; # server 127.0.0.1:9005 weight=1 fail_timeout=5; # server 127.0.0.1:9006 weight=1 fail_timeout=5; # server 127.0.0.1:9007 weight=1 fail_timeout=5; # server 127.0.0.1:9008 weight=1 fail_timeout=5; # server 127.0.0.1:9009 weight=1 fail_timeout=5; # server 127.0.0.1:9010 weight=1 fail_timeout=5; # least_conn; # } sendfile off; #tcp_nopush on; server_names_hash_bucket_size 128; ## Start: Timeouts ## client_body_timeout 10; client_header_timeout 10; keepalive_timeout 30; send_timeout 10; keepalive_requests 10; ## End: Timeouts ## #gzip on; server { listen 80; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; ## Caching Static Files, put before first location #location ~* \.(jpg|jpeg|png|gif|ico|css|js)$ { # expires 14d; # add_header Vary Accept-Encoding; #} # For Naxsi remove the single # line for learn mode, or the ## lines for full WAF mode location / { #include /nginx/conf/mysite.rules; # see also http block naxsi include line ##SecRulesEnabled; ##DeniedUrl "/RequestDenied"; ##CheckRule "$SQL >= 8" BLOCK; ##CheckRule "$RFI >= 8" BLOCK; ##CheckRule "$TRAVERSAL >= 4" BLOCK; ##CheckRule "$XSS >= 8" BLOCK; root html; index index.html index.htm; } # For Naxsi remove the ## lines for full WAF mode, redirect location block used by naxsi ##location /RequestDenied { ## return 412; ##} ## Lua examples ! # location /robots.txt { # rewrite_by_lua ' # if ngx.var.http_host ~= "localhost" then # return ngx.exec("/robots_disallow.txt"); # end # '; # } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # single backend process # fastcgi_pass myLoadBalancer; # or multiple, see example above # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl spdy; # server_name localhost; # ssl on; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_timeout 5m; # ssl_prefer_server_ciphers On; # ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:ECDH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!eNULL:!MD5:!DSS:!EXP:!ADH:!LOW:!MEDIUM; # location / { # root html; # index index.html index.htm; # } #} }

注：rtmp中的“application live” ,application+空格+live，live即使访问路径，如localhost:1935/live。 4、在nginx.exe所在的目录，即根目录下，进入cmd窗口，输入nginx.exe或.\nginx.exe，启动nginx。 5、可以直接浏览器输入localhost验证是否启动nginx，若出现nginx的主页面，则成功。 6、将服务器状态检查程序解压，放到nginx根目录下。在这里插入图片描述 7、将ffmpeg解压后，将其bin目录添加环境变量。 8、安装VLC

三、ffmpeg推流

ffmpeg推流是为了确定nginx的1935端口已打开并运行rtmp推流功能，以排除故障等问题。 1、在测试视频所在文件夹打开cmd窗口，输入指令 ffmpeg.exe -re -i .\视频名.mp4 -vcodec libx264 -acodec aac -f flv rtmp://127.0.0.1:1935/live 2、若出现以下画面则推流失败，是因为nginx的1935端口未开启，或是rtmp未推流。

请添加图片描述 3、若出现以下画面，则成功，frame, fps等信息会不断地变化。

4、打开VLC，在左上角媒体中选择打开网络串流，在网络URL中输入rtmp://127.0.0.1:1935/live，点击播放。请添加图片描述 5、若是显示出视频，则成功。

四、无人机rtmp推流

1、保证电脑和无人机遥控器（或遥控器连接的手机）在同一局域网中（即同一路由器或热点）。 2、电脑确认ip地址，打开cmd窗口输入命令ipconfig，确定电脑ip地址。 3、无人机进入自定义直播功能中，输入地址，一般为 rtmp://192.168.x.x:1935/live 或 rtmp://10.0.x.x:1935/live。 4、打开VLC，在左上角媒体中选择打开网络串流，在网络URL中输入与 3 中同样的ip地址，点击播放。请添加图片描述 5、若显示出无人机画面，则成功，一般延迟在 3~10s 内。（我是成功了，哈哈哈哈哈！）注：若无人机无法传输视频，那么把Windows系统的防火墙关闭再试一试。

五、Python获取无人机实时视频 import cv2 import time if __name__ == '__main__': # 无人机rtmp视频流url video_path = "rtmp://192.168.x.x:1935/live" # opencv获取视频流 capture = cv2.VideoCapture(video_path) while True: fps = 0.0 t1 = time.time() # 读取某一帧 ref, frame = capture.read() fps = (fps + (1. / (time.time() - t1))) / 2 print("fps= %.2f" % (fps)) frame = cv2.putText(frame, "fps= %.2f" % (fps), (0, 40), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 255, 0), 2) cv2.imshow("video", frame) c = cv2.waitKey(1) & 0xff if c == 27: capture.release() break print("Video Detection Done!") capture.release() cv2.destroyAllWindows()
