改代码是在https://github.com/johnf/m3u8-segmenter基础上的修改和添加。

原来的工具主要有两个问题：

1. 切片的时间长度不能完全保证是参数传入的'-d'值
2. 当最后一个切片视频没有实际设置的最大切片长度时，仍然在m3u8文件显示为最大时间长度 经过修正，现在这两个问题都已经解决，并添加了AES加密机制。

aes加密方式为：CBC, 128bit Key, pkcs7padding填充。（苹果的mediafilesegmenter工具也是这种加密机制）切片加密的视频可以直接使用苹果手机浏览器访问播放。

为ts文件实现aes加密机制运行方式： ./segmenter -i test.ts -d 10 -p seg -m seg.m3u8 -u '' -K "http://10.130.29.36/self.key"

Inactive and Deprecated

I no longer have much time to work on this project and for the most part it is deprecated now that both ffmpeg and libav have direct support for segmenting and creating m3u files. Quite happy to point this elsewhere if someone else would like to take over the project.

m3u8-segmenter

m3u8-segmenter is an Apple HTTP Live Segmenter. It takes an MPEG-TS stream from a tool like ffmpeg and breaks it up into multiple ts-segments suitable for HTTP Live streaming from devices like iPhones. It also creates the M3U8 stream descriptor which is required for this type of stream.

It was originally written by Chase Douglas and is now maintained by John Ferlito.

##Installing

TO install from source you will need to make sure you have the libav/ffmpeg libraries installed. On Ubuntu/Debian you would run

apt-get install libavformat-dev

You can then build and install m3u8-segmenter by running

aclocal
automake -ac
autoconf
./configure
make
sudo make install

Usage

Some example command lines

ffmpeg -loglevel quiet  -i big_buck_bunny.ogv -f mpegts - | \
  m3u8-segmenter -i - -d 10 -p tmp/big_buck_bunny -m tmp/big_buck.m3u8 -u http://inodes.org/bigbuck/

ffmpeg -er 4 -i input.mp3 -f mpegts -acodec libmp3lame -ar 22050 -ab 32k -vn - | \
  m3u8-segmenter -i - -d 10 -p outputdir/prefix -m outputdir/output.m3u8 -u http://domain.com/

Note on Patches/Pull Requests

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with Rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
