[转]做自己的m3u8点播系统使用HTTP Live Streaming(HLS技术）

[FMS]使用ffmpeg来完成对flv、mp4、mp3等格式的转化,使用ffmpeg或segmenter完成对视频/音频格式文件的切割，切割为m3u8格式及ts文件

1、 为何要使用HTTP Live Streaming

可以参考wikipedia

HTTP Live Streaming（缩写是 HLS）是一个由苹果公司提出的基于HTTP的流媒体 网络传输协议。是苹果公司QuickTime X和iPhone软件系统的一部分。它的工作原理是把整个流分成一个个小的基于HTTP的文件来下载，每次只下载一些。当媒体流正在播放时，客户端可以选择从许多不同的备用源中以不同的速率下载同样的资源，允许流媒体会话适应不同的数据速率。在开始一个流媒体会话时，客户端会下载一个包含元数据的extended M3U (m3u8) playlist文件，用于寻找可用的媒体流。

HLS只请求基本的HTTP报文，与实时传输协议（RTP)不同，HLS可以穿过任何允许HTTP数据通过的防火墙或者代理服务器。它也很容易使用内容分发网络来传输媒体流。

2、 HTTP Live Streaming技术方案

HTTP服务：使用Nginx提供HTTP服务，通过使用nginx-rtmp-module https://github.com/arut/nginx-rtmp-module 来增加对HLS的支持

使用ffmpeg来完成对flv、mp4、mp3等格式的转化,使用ffmpeg或segmenter完成对视频/音频格式文件的切割，切割为m3u8格式及ts文件

在nginx.conf中增加rtmp模块的相关配置，配置例子

rtmp {

server {

listen 1935;

chunk_size 4000;

# TV mode: one publisher, many subscribers

application mytv {

# enable live streaming

live on;

# record first 1K of stream

record all;

record_path /tmp/av;

record_max_size 1K;

# append current timestamp to each flv

record_unique on;

# publish only from localhost

allow publish 127.0.0.1;

deny publish all;

#allow play all;

}

# Transcoding (ffmpeg needed)

application big {

live on;

# On every pusblished stream run this command (ffmpeg)

# with substitutions: $app/${app}, $name/${name} for application & stream name.

#

# This ffmpeg call receives stream from this application &

# reduces the resolution down to 32×32. The stream is the published to

# ‘small’ application (see below) under the same name.

#

# ffmpeg can do anything with the stream like video/audio

# transcoding, resizing, altering container/codec params etc

#

# Multiple exec lines can be specified.

exec /usr/local/bin/ffmpeg -re -i rtmp://localhost:1935/$app/$name -vcodec flv -acodec copy -s 32×32 -f flv rtmp://localhost:1935/small/${name};

}

application small {

live on;

# Video with reduced resolution comes here from ffmpeg

}

application mypush {

live on;

# Every stream published here

# is automatically pushed to

# these two machines

#push rtmp1.example.com;

#push rtmp2.example.com:1934;

}

application mypull {

live on;

# Pull all streams from remote machine

# and play locally

#pull rtmp://rtmp3.example.com pageUrl=www.example.com/index.html;

}

# video on demand

application vod {

play /var/flvs;

}

application vod2 {

play /var/mp4s;

}

# Many publishers, many subscribers

# no checks, no recording

application videochat {

live on;

# The following notifications receive all

# the session variables as well as

# particular call arguments in HTTP POST

# request

# Make HTTP request & use HTTP retcode

# to decide whether to allow publishing

# from this connection or not

on_publish http://localhost:8080/publish;

# Same with playing

on_play http://localhost:8080/play;

# Publish/play end (repeats on disconnect)

on_done http://localhost:8080/done;

# All above mentioned notifications receive

# standard connect() arguments as well as

# play/publish ones. If any arguments are sent

# with GET-style syntax to play & publish

# these are also included.

# Example URL:

#   rtmp://localhost/myapp/mystream?a=b&c=d

# record 10 video keyframes (no audio) every 2 minutes

record keyframes;

record_path /var/vc;

record_max_frames 10;

record_interval 2m;

# Async notify about an flv recorded

on_record_done http://localhost:8080/record_done;

}

# 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 /var/app;

hls_fragment 5s;

}

}

}

# HTTP can be used for accessing RTMP stats

http {

server {

listen      8080;

# This URL provides RTMP statistics in XML

location /stat {

rtmp_stat all;

# Use this stylesheet to view XML as web page

# in browser

rtmp_stat_stylesheet stat.xsl;

}

location /stat.xsl {
# XML stylesheet to view RTMP stats.
# Copy stat.xsl wherever you want
# and put the full directory path here
root /path/to/stat.xsl/;
}
location /hls {
# Serve HLS fragments
alias /var/app;
}
}
}

6、 安装segmenter

svn co http://httpsegmenter.googlecode.com/svn/

cd svn/trunk

gcc -Wall -g segmenter.c -o segmenter -lavformat -lavcodec -lavutil -std=c99

cp segmenter /usr/bin/

从优酷上下载一个视频文件，假定为baluobu.flv

找个mp3文件，假定为10year.mp3

mkdir /var/flvs /var/mp4s /var/vc /var/app /var/app/10year /var/app/baluobu

使用ffmpeg将测试视频和音频转为mpeg ts格式文件

ffmpeg -i /var/flvs/baluobu.flv -f mpegts -acodec libmp3lame -ar 48000 -ab 128k -vcodec libx264 -b 96k -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -subq 5 -trellis 1 -refs 1 -coder 0 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 200k -maxrate 96k -bufsize 96k -rc_eq ‘blurCplx^(1-qComp)’ -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 -aspect 320:240 -g 30 -async 2 /var/app/baluobu/baluobu.ts

ffmpeg -i /var/flvs/10year.mp3 -f mpegts -acodec libmp3lame -ar 48000 -ab 128k -vcodec libx264 -b 96k -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -subq 5 -trellis 1 -refs 1 -coder 0 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 200k -maxrate 96k -bufsize 96k -rc_eq ‘blurCplx^(1-qComp)’ -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 -aspect 320:240 -g 30 -async 2 /var/app/10year/10year.ts

cd /var/app/10year

segmenter -i 10year.ts -d 5 -o 10year -x 10year.m3u8

cd /var/app/baluobu

segmenter -i baluobu.ts -d 5 -o buluobu -x baluobu.m3u8

7、测试

简单起见使用酷播网页视频播放器测试，下载 http://www.52player.com/VideoPlayer/2014/012326.html

http://demo.cuplayer.com:8080/hls/10year/10year.m3u8

http://demo.cuplayer.com:8080/hls/baluobu/baluobu.m3u8

如果无问题，说明已经正常配置成功了HTTP Live Streaming（HLS）服务

可以再iOS设备上使用safari访问以上地址

或者在android机器上安装vplayer后访问以上地址

如果需要通过网页形式提供在线视频，需要在nginx的mime.types文件中添加如下MIME类型：

.m3u8 application/x-mpegURL
.ts video/MP2T

同时在HTML5页面中使用video标签包含视频的m3u8文件

8、开发说明

iOS已经原生支持HTTP Live Streaming（HLS），只需要使用MPMoviePlayerController播放以上地址即可

apple文档：http://bit.ly/Rnpsef

Android 3.x以后通过新增的NuPlayer类才支持HTTP Live streaming，而且功能也较弱，为简化处理，可以使用

Vitamio http://vov.io/vitamio/ 或 http://code.taobao.org/p/oplayer/src/ 下载

Servestream http://sourceforge.net/projects/servestream/

nginx-rtmp-module 本身也支持RTMP协议，从而也可以基于nginx来搭建在线直播系统。

如果无问题，说明已经正常配置成功了HTTP Live Streaming（HLS）服务

可以再iOS设备上使用safari访问以上地址

或者在android机器上安装vplayer后访问以上地址

如果需要通过网页形式提供在线视频，需要在nginx的mime.types文件中添加如下MIME类型：

.m3u8 application/x-mpegURL
.ts video/MP2T

同时在HTML5页面中使用video标签包含视频的m3u8文件

8、开发说明

iOS已经原生支持HTTP Live Streaming（HLS），只需要使用MPMoviePlayerController播放以上地址即可

apple文档：http://bit.ly/Rnpsef

Android 3.x以后通过新增的NuPlayer类才支持HTTP Live streaming，而且功能也较弱，为简化处理，可以使用

Vitamio http://vov.io/vitamio/ 或 http://code.taobao.org/p/oplayer/src/ 下载

Servestream http://sourceforge.net/projects/servestream/

nginx-rtmp-module 本身也支持RTMP协议，从而也可以基于nginx来搭建在线直播系统。
