建立存放视频目录

mkdir /mnt/media/vod /mnt/media/app /mnt/media/vedio

vi /usr/local/nginx/conf/nginx.conf

#filename:nginx.conf

#user  nobody;

worker_processes  1;

error_log  logs/error.log;

#error_log  logs/error.log  notice;

#error_log  logs/error.log  info;

pid   logs/nginx.pid;

use epoll;

worker_connections  1024;

}

rtmp {

server {

listen 1935;

# video on demand

application vod {

play /mnt/media/vod;

}

# HLS

# HLS requires libavformat & should be configured as a separate

# NGINX module in addition to nginx-rtmp-module:

# ./configure … –add-module=/path/to/nginx-rtmp-module/hls …

# For HLS to work please create a directory in tmpfs (/tmp/app here)

# for the fragments. The directory contents is served via HTTP (see

# http{} section in config)

#

# Incoming stream must be in H264/AAC/MP3. 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.

#

application hls {

hls on;

hls_path /mnt/media/app;

hls_fragment 10s;

}

}

}

http {

include mime.types;

default_type application/octet-stream;

sendfile on;

keepalive_timeout 65;

gzip on;

将nginx添加到系统服务

14安装切片工具segmenter

git clone https://github.com/johnf/m3u8-segmenter.git

cd m3u8-segmenter/

gcc -Wall -g m3u8-segmenter.c -o segmenter -lavformat

cp segmenter /usr/bin/

15测试

上传MP4文件到/mnt/media/video/

将MP4转换为flv格式

cd /mnt/media/video/

ffmpeg -i movie1.mp4 -y -vcodec libx264 -vf scale="640:-1" -r 15 -acodec libfaac ../vod/movie1.flv

cd ../vod

mv movie1.flv movie1-src.flv

添加关键帧以支持拖动播放

yamdi -i movie1-src.flv -o movie1.flv 

将flv转换成ts文件

mkdir /mnt/media/app/movie1

还在vod目录下

ffmpeg -y -i movie1.flv -f mpegts -c:v copy -c:a copy -vbsf h264_mp4toannexb /mnt/media/app/movie1/main.ts

切片

cd /mnt/media/app/movie1/

segmenter -i main.ts -d 10 -p movie1 -m movie1.m3u8 -u http://YOURSERVERIP/hls/movie1/

测试
