Nginx模块之————RTMP模块的FFmpeg的配置问题是FFmpeg的连续退出

rtmp {
    server {
        listen ;

        application live {
             allow publish all;
             allow play all;
             live on;

             exec /root/bin/ffmpeg -i rtmp://localhost/live/$name
                        -c:v libx264 -c:a libfdk_aac -b:v 256k -b:a 32k
                        -f flv rtmp://localhost/hls/$name_low
                        -c:v libx264 -c:a libfdk_aac -b:v 768k -b:a 96k
                        -f flv rtmp://localhost/hls/$name_mid
                        -c:v libx264 -c:a libfdk_aac -b:v 1024k -b:a 128k
                        -f flv rtmp://localhost/hls/$name_hi;
        }

        application hls {
            live on;
            hls on;
            hls_path /mnt/hls;
            hls_fragment 15s;

            hls_variant _low BANDWIDTH=;
            hls_variant _mid BANDWIDTH=;
            hls_variant _hi  BANDWIDTH=;

        }

    }
}

解决办法：

hls_continuous on; //打开HLS连续模式。 在这种模式下，HLS序列号从上次停止的地方开始。 老片段被保存。 默认为关闭。
