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 portchunk_size 4000;application show {live on;# Turn on HLShls 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 cacheadd_header Cache-Control no-cache;# CORS setupadd_header 'Access-Control-Allow-Origin' '*' always;add_header 'Access-Control-Expose-Headers' 'Content-Length';# allow CORS preflight requestsif ($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/;}
}具体什么意思可以查找帮助文档：Directives · arut/nginx-rtmp-module Wiki · GitHub
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;}}

# # See sample authentication script at:

#
# # auth_http localhost/auth.php;
# # pop3_capabilities "TOP" "USER";
# # imap_capabilities "IMAP4rev1" "UIDPLUS";
#
# server {
# listen localhost:110;
# protocol pop3;
# proxy on;
# }
#
# server {
# listen localhost:143;
# protocol imap;
# proxy on;
# }
#}
然后重启nginx
sudo service nginx restart4 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：
