Linux系統下實現監控攝像頭RTSP協議對接騰訊雲直播

Linux系統下實現監控攝像頭RTSP協議對接騰訊雲直播

1.ffmpeg安裝

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安裝和配置

安裝nginx組件

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

下載nginx-rtmp-module

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

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

安裝nginx

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

編譯和安裝

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

3.開通騰訊雲直播

（1）點擊當即使用開通服務

（2）點擊輔助工具選擇地址生成器生成推流地址

4. nginx-rtmp配置

（1）建立nginx本地文件存放目錄

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;  #監聽的端口  

    chunk_size 4000;

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

（3）檢查配置是否正確

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

（4）啓動nginx

/usr/local/nginx/sbin/nginx

5.ffmpeg拉攝像頭的視頻流

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可能會報 Could not find codec parameters for stream 0 (Video: h264, none) 錯誤，ffmpeg默認使用udp方式傳輸，在使用：avformat\_find\_stream\_info 會出現返回 codec\_id ==AV\_CODEC\_ID\_NONE 的狀況；

若是id = none 的狀況在 打開解碼器的時候確定會報錯，因此在 執行 avformat\_find\_stream\_info 的時候有必要判斷一下視頻信息的有效性！

在 avformat\_open\_input打開流地址以前 強制ffmpeg 以tcp傳輸 ，能夠解決上面返回 none的狀況。

6.檢測

(1) 檢測ffmpeg是否從攝像頭拉流到nginx-rtmp, 若是成功，能夠看到：

（2）檢測是否推送到騰訊雲

若是推送成功則能夠在流管理界面的狀態看到直播中的字樣。

點擊操做中的測試則能夠看到攝像頭的直播畫面以下：
