onvif客户端c源码游戏服务端源码

一、说明1. 业务场景直播源是rtsp或rtmp等onvif客户端c源码，播放端不支持直接播放rtsp(如网页播放)源视频带宽和负载有限onvif客户端c源码，不支持很多用户访问客户端点播2. 流程使用ffmpeg从节目源拉流推流到nginx-rtmp/flv服务客户端从nginx服务器拉流观看视频3. 本文工具ffmpegnginxVLC(用来测试拉流)

以下两个模块选择一个安装：

nginx-http-flv-modulenginx-rtmp-module

其实nginx flv也是基于nginx-rtmp-module的流媒体服务器。

功能对比：

功能nginx-http-flv-modulenginx-rtmp-module备注HTTP-FLV (播放)√x支持HTTPS-FLV和chunked回复GOP缓存√x虚拟主机√x省略listen配置√见备注配置中必须有一个listen纯音频支持√见备注wait_video或wait_key开启后无法工作定时打印访问记录√xJSON风格的stat√x

二、FFMPEG 的安装1. Ubuntu环境(1) apt-get安装# 可通过PPA进行安装sudo add-apt-repository ppa:kirillshkrogalev/ffmpeg-nextsudo apt-get updatesudo apt-get install ffmpeg# 查看是否安装成功：ffmpeg -version(2) 编译安装sudo apt-get install -y autoconf automake build-essential git libass-dev libfreetype6-dev libsdl2-devsudo apt-get install -y libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texinfo wget zlib1g-dev sudo apt-get install -y nasam yasm cmake mercurial ./configure --enable-shared --prefix=/usr/local/ffmpeg --disable-x86asmsudo make sudo make install

在 /etc/ld.so.conf中onvif客户端c源码，末尾添加 /usr/local/ffmpeg/lib，执行sudo ldconfig

为 ffmpeg 加入环境变量

vi /etc/profile

加入以下内容:

export PATH="/usr/local/ffmpeg/bin:$PATH"

然后保存并运行source /etc/profile

2. CentOS7(支持nVidia硬件解码)

硬件环境：nVidia 20602块

(1) 安装nVidia驱动(A) yum方式安装nVidia驱动rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.orgrpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpmyum install yum-plugin-fastestmirrorsudo vim /lib/modprobe.d/dist-blacklist.conf

dist-blacklist.conf

#blacklist nvidiafbblacklist nouveauoptions nouveau modeset=0mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bakdracut /boot/initramfs-$(uname -r).img $(uname -r)lspci | grep nouveau

没有输出，说明屏蔽默认带有的nouveau成功。

一些命令：

sudo yum install nvidia-detect nvidia显卡检测nvidia-detect -v 检测结果# yum -y install kmod-nvidia 安装显卡驱动 这一步应该不需要 (B) run脚本方式安装nVidia驱动

参考：https://github.com/keylase/nvidia-patch

cd /opt/nvidiawget https://international.download.nvidia.com/XFree86/Linux-x86_64/430.40/NVIDIA-Linux-x86_64-430.40.runchmod +x NVIDIA-Linux-x86_64-430.40.run./NVIDIA-Linux-x86_64-430.40.run --kernel-source-path=/usr/src/kernels/3.10.0-957.27.2.el7.x86_64# 下面是移除NVENC同时运行最大数量的限制 restriction on maximum number of simultaneous NVENCgit clone https://github.com/keylase/nvidia-patchcd nvidia-patchbash ./patch.sh

如果需要卸载，使用命令：

./NVIDIA-Linux-x86_64-430.40.run --uninstall(2) 安装Cuda

参考

三、nginx的rtmp/flv模块安装1. CentOS7环境(1) 安装nginx-http-flv-module模块A. 通过nginx.confyum install https://extras.getpagespeed.com/release-el$(rpm -E %{rhel})-latest.rpmyum install nginx-module-flv安装完毕后，HTTP-FLV功能的配置文件http-flv.conf和RTMP功能的配置文件rtmp.conf会被放在/etc/nginx/http-flv目录下通过include手工将它们添加到/etc/nginx/nginx.conf，以开启HTTP-FLV和RTMP功能：http { ... include /etc/nginx/http-flv/http-flv.conf;}include /etc/nginx/http-flv/rtmp.conf;# 添加以下配置到/etc/nginx/nginx.conf，启动或者重启NGINX来启用本模块：load_module modules/ngx_http_flv_live_module.so;# 注意# 上述的配置必须位于events配置项之前，否则NGINX不能启动。# 更新可以通过yum update来完成。关于其他NGINX模块的详情见GetPageSpeed。B. 源码编译安装cd rootgit clone https://github.com/winshining/nginx-http-flv-modulewget http://nginx.org/download/nginx-1.8.1.tar.gz tar -zxvf nginx-1.8.1.tar.gz cd nginx-1.8.1 ./configure --add-module=/root/nginx-http-flv-module --with-http_ssl_module make && make install(2) 安装 nginx-rtmp-module# 下载nginx-rtmp-modulegit clone https://github.com/arut/nginx-rtmp-module.git# 编译安装nginxwget http://nginx.org/download/nginx-1.8.1.tar.gz tar -zxvf nginx-1.8.1.tar.gz cd nginx-1.8.1 ./configure --prefix=/usr/local/nginx --add-module=../nginx-rtmp-module --with-http_ssl_module make && make install# 设置nginxvi /usr/local/nginx/conf/nginx.conf

nginx.conf内容

worker_processes 1;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 809; server_name localhost; location / { root html; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }} rtmp { out_queue 4096; out_cork 8; max_streams 4096; server { listen 90; drop_idle_publisher 30s; application live { live on; } } }# 启动nginx/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf# 如果要卸载# 如果有自启动，则删除 Nginx 的自启动chkconfig nginx off服务 nginx 信息读取出错：没有那个文件或目录# 查找nginx的安装目录whereis nginxnginx: /usr/local/nginx# 停止nginx服务/usr/local/nginx/sbin/nginx -s stop# 删除安装目录rm -rf /usr/local/nginx/# 查找是否还有残余的find / -name nginx/usr/local/lib64/nginx-1.15.7/objs/nginxrm -rf /usr/local/lib64/nginx-1.15.7/2. windows环境安装nginx-rtmp(1) 下载

官方的nginx不带rtmp模块，在下面地址可下载windows版本的nginx+rtmp:https://github.com/illuspas/nginx-rtmp-win32使用：nginx-rtmp-win32-1.2.1.zip

(2) 配置文件

nginx.conf

worker_processes 1;error_log logs/error.log debug;events { worker_connections 1024;}rtmp_auto_push on;rtmp_auto_push_reconnect 1s;rtmp_socket_dir /tmp;rtmp { out_queue 4096; out_cork 8; max_streams 4096; server { listen 90; drop_idle_publisher 30s; application live { live on; } }}http { server { listen 80; location / { root html; } location /stat { rtmp_stat all; rtmp_stat_stylesheet stat.xsl; } location /stat.xsl { root html; } }}

/tmp需要有可写权限。

上面示例中的推流/拉流地址http://ip:90/live/test

四、测试# 推流测试ffmpeg -hwaccel cuvid -c:v h264_cuvid -i "视频资源源地址" -c:v h264_nvenc -an -crf 20 -b:a 96k -b:v 2048k -preset medium -tune animation -vf scale_npp=1024:-1 -f flv rtmp://ip:90/live/test# 拉流测试使用VLC Media Player打开网址： rtmp://ip:90/live/test
