#Chapter#

Chapter is a simple gem to set mp4 chapter information.

To use it, you'll need mp4v2 installed on your system.

On OS X:

brew install mp4v2

On FreeBSD:

cd /usr/ports/multimedia/mp4v2 && make install clean

On other systems you might need to compile it yourself. Please refer to the mp4v2 documentation on how to do that. ##Installation## Via Rubygems:

gem install chapter

Or add the gem to your Gemfile:

gem 'chapter'

require 'chapter'
chapters = Chapter.chapters('/path/to/file.m4a')

chapters will be an array of hashes. Each hash represents a chapter with its position and duration (both in microseconds) and its title. ####Example

[
  {"title"=>"Introduction", "duration"=>12325, "position"=>0},
  {"title"=>"Discussion", "duration"=>655325, "position"=>12325}
]

Setting the chapters is just as simple:

require 'chapter'
chapters = [
    {"title"=>"Introduction", "duration"=>12325},
    {"title"=>"Discussion", "duration"=>655325}
]
Chapter.set_chapters("/path/fo/file.m4a", chapters)

CAUTION: set_chapters will overwrite any existing chapters in the file.
