关于HLS

HTTP Live Streaming（HLS）是苹果公司实现的基于HTTP的流媒体传输协议，可实现流媒体的直播和点播，相对于常见的流媒体直播协议，例如RTMP协议、RTSP协议、MMS协议等，HLS直播最大的不一样在于，直播客户端获取到的，并非一个完整的数据流。HLS协议在服务器端将直播数据流存储为连续的、很短时长的媒体文件（MPEG-TS格式），而客户端则不断的下载并播放这些小文件，由于服务器端老是会将最新的直播数据生成新的小文件，这样客户端只要不停的按顺序播放从服务器获取到的文件，就实现了直播。因而可知，基本上能够认为，HLS是以点播的技术方式来实现直播。因为数据经过HTTP协议传输，因此彻底不用考虑防火墙或者代理的问题，并且分段文件的时长很短，客户端能够很快的选择和切换码率，以适应不一样带宽条件下的播放。不过HLS的这种技术特色，决定了它的延迟通常老是会高于普通的流媒体直播协议。css

下载nginx源码包

cd /tmp

#wget http://nginx.org/download/nginx-1.14.0.gar.gz
# 使用华为云镜像
wget https://mirrors.huaweicloud.com/nginx/nginx-1.14.0.tar.gz

# 解压缩
tar -xvzf ./nginx-1.14.0.tar.gz

下载nginx-rtmp源码

# 下载nginx-rtmp模块源码
wget https://github.com/arut/nginx-rtmp-module/archive/v1.2.1.tar.gz

# 解压缩，这个须要用到，转入正式目录
tar -xvzf ./v1.2.1.tar.gz
mv /tmp/nginx-rtmp-module-1.2.1 /usr/local/nginx-rtmp-module

更新相关依赖包

yum -y install pcre* openssl openssl-devel

建立用户和组

# 建立组
groupadd nginx

# 建立不容许登陆，无主目录的用户
useradd -s /sbin/nologin -g nginx -M nginx

安装nginx跟rtmp模块

cd /tmp/nginx-1.14.0

./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --add-module=/usr/local/nginx-rtmp-module  

make & make install

参数	说明
--user=nginx	指定运行权限的用户
--group=nginx	指定运行的权限用户组
--prefix=/usr/local/nginx	指定安装路径
--with-http_stub_status_module	支持nginx状态查询
--with-http_ssl_module	开启ssl支持
--with-http_gzip_static_module	开启GZIP功能
--add-module=/usr/local/nginx-rtmp-module	添加nginx-rtmp-module模块

        listen 1935;

        # HLS
        # For HLS to work please create a directory in tmpfs (/tmp/hls here)
        # for the fragments. The directory contents is served via HTTP (see
        # http{} section in config)
        #
        # Incoming stream must be in H264/AAC. For iPhones use baseline H264
        # profile (see ffmpeg example).
        # This example creates RTMP stream from movie ready for HLS:
        #
        # ffmpeg -loglevel verbose -re -i movie.avi  -vcodec libx264
        #    -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
        #    -f flv rtmp://localhost:1935/hls/movie
        #
        # If you need to transcode live stream use 'exec' feature.
        #

        # rtmp推流请求路径
        application hls {
            # 开启实时
            live on;

            # 开启hls
            hls on;

            # 对视频切片进行保护，这样就不会产生马赛克了
            wait_key on; 

            # rtmp推流请求路径，文件存放路径
            hls_path /data/video/hls;
