ubuntu中使用ffmpeg和nginx推http hls视频流

视频流除了rtmp、rtsp，还有一种是http的hls流，使用http协议传输hls格式的视频数据。

nginx支持推送hls视频流，使用的是rtmp模块，即rtmp流推送成功了，hls流也没问题。怎么推送rtmp流，请参考我的文章：ubuntu中使用ffmpeg和nginx推流rtmp视频-CSDN博客，在此基础上加一些配置就可以推送hls视频了。

1 修改/etc/nginx/nginx.conf，在rtmp配置中增加hls的配置：

rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000;

        application show {
            live on;

            # Turn on HLS
            hls on;
            hls_path /mnt/hls/;
            hls_fragment 3;
            hls_playlist_length 60;
        }
    }
}

其中，

# Turn on HLS
hls on;
hls_path /mnt/hls/;
hls_fragment 3;
hls_playlist_length 60;

是新增的，配置中/mnt/hls/是hls的播放列表和视频文件路径，可修改。

2 修改http服务器配置，新增如下配置：

server {
    listen 8080;

    location /hls {
        # Disable cache
        add_header Cache-Control no-cache;

        # CORS setup
        add_header 'Access-Control-Allow-Origin' '*' always;
        add_header 'Access-Control-Expose-Headers' 'Content-Length';

        # allow CORS preflight requests
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Max-Age' 1728000;
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            add_header 'Content-Length' 0;
            return 204;
        }

        types {
            application/vnd.apple.mpegurl m3u8;
            video/mp2t ts;
        }

        root /mnt/;
    }
}

3 完整的nginx.conf内容：

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
	worker_connections 768;
	# multi_accept on;
}

rtmp {
        server {
                listen 1935;
                chunk_size 4096;
 
                application live {
                        live on;
                        record off;
                        
                        hls on;
                        hls_path /mnt/hls;
                        hls_fragment 3;
                        hls_playlist_length 60;

                        dash on;
                        dash_path /mnt/dash;
                }
        }
}


http {

#mail {
#	# See sample authentication script at:
#	# http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
#
#	# auth_http localhost/auth.php;
#	# pop3_capabilities "TOP" "USER";

#
#	server {
#		listen     localhost:110;

#	}
#
#	server {

然后重启nginx

sudo service nginx restart

4 推流和拉流测试

按照以前rtmp测试的文章，推流命令为：

ffmpeg -stream_loop -1 -re -i /mnt/hgfs/vmware_ubuntu_share/input.mp4 -c copy -f flv -flvflags no_duration_filesize  rtmp:192.168.63.128:1935/live/1

推流成功。

使用ffplay拉流，当然正规的是用浏览器播放，

ffplay http://192.168.63.128:8080/hls/1.m3u8

命令中：

192.168.63.128:8080为ubuntu nginx服务器的地址和端口，8080端口在配置服务器的时候设置了，地址要改成自己的ubuntu地址。

/hls/1.m3u8中的"1"是推流命令中的最后那个"1"，正规名称叫streamname，/hls是固定的。

拉流也是成功的。

用浏览器测试下吧，edge中搜一个hls播放器插件，安装好：

把hls流地址复制到浏览器地址栏后就可以用浏览器看视频了：
