Linux系统下实现监控摄像头RTSP协议对接腾讯云直播

1.ffmpeg安装

sudo yum localinstall --nogpgcheck https://download1.rpmfusion.org/free/el/rpmfusion-free-release-7.noarch.rpm https://download1.rpmfusion.org/nonfree/el/rpmfusion-nonfree-release-7.noarch.rpm
yum -y install ffmpeg

2.nginx-rtmp安装和配置

安装nginx组件

yum -y install gcc openssl-devel pcre-devel zlib-devel

下载nginx-rtmp-module

//方式一：git命令下载
git clone https://github.com/arut/nginx-rtmp-module.git

//方式二：下载nginx-rtmp-module-1.2.0.tar.gz
//解压
tar -zxvf nginx-rtmp-module-1.2.0.tar.gz
//重命名
mv nginx-rtmp-module-1.2.0 nginx-rtmp-module

安装nginx

tar zxvf nginx-1.14.2.tar.gz 
cd nginx-1.14.2/

编译和安装

./configure --prefix=/usr/local/nginx  --add-module=../nginx-rtmp-module  --with-http_ssl_module 
make 
make install 

3.开通腾讯云直播

（1）点击立即使用开通服务

（2）点击辅助工具选择地址生成器生成推流地址

4. nginx-rtmp配置

（1）创建nginx本地文件存放目录

mkdir -p /mnt/share/html/hls

（2）rtmp配置

vim /usr/local/nginx/conf/nginx.conf


#文件末尾追加
rtmp {

server {

    listen 1935;  #监听的端口  

    chunk_size 4000;

    # rtmp推流请求路径 
    application hls {   
        live on;
        hls on;
        # 本地保存hlv格式文件
        hls_path /mnt/share/html/hls; 
        hls_fragment 10s;
        # 转推[腾讯云](https://l.gushuji.site/tencent)
        push rtmp://106630.livepush.myqcloud.com/live/rtsptest?txSecret=b8d28c20ab68f2467727b837eefcb4a2&txTime=5F140099;
    }
  }
} 

（3）检查配置是否正确

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

（4）启动nginx

/usr/local/nginx/sbin/nginx

5.ffmpeg拉摄像头的视频流

ffmpeg -rtsp_transport tcp -i "rtsp://admin:1111aaaa@172.19.20.201:554/cam/realmonitor?channel=1&subtype=0" -vcodec copy -acodec aac -ar 44100 -strict -2 -ac 1 -f flv -s 4000x3000 -q 10 -f flv "rtmp://127.0.0.1:1935/hls"

注：若不加-rtsp_transport可能会报 Could not find codec parameters for stream 0 (Video: h264, none) 错误，ffmpeg默认使用udp方式传输，在使用：avformat_find_stream_info 会出现返回 codec_id ==AV_CODEC_ID_NONE 的情况；

如果id = none 的情况在 打开解码器的时候肯定会报错，所以在 执行 avformat_find_stream_info 的时候有必要判断一下视频信息的有效性！

在 avformat_open_input打开流地址之前 强制ffmpeg 以tcp传输 ，可以解决上面返回 none的情况。

6.检测

(1) 检测ffmpeg是否从摄像头拉流到nginx-rtmp, 如果成功，可以看到：

（2）检测是否推送到腾讯云

如果推送成功则可以在流管理界面的状态看到直播中的字样。

点击操作中的测试则可以看到摄像头的直播画面如下：
