VideoFile

A simple gem for generating video thumbnails.

Installation

Install FFMPEG and TurboJPEG. For Ubuntu/Debian:

Add this line to your application's Gemfile:

gem 'video_file'

And then execute:

$ bundle

Or install it yourself as:

$ gem install video_file

Usage

file = VideoFile::File.new 'video.mp4'
puts file.duration

thumbnailer = VideoFile::Thumbnailer.new file, 128
jpeg_data = thumbnailer.get 3.0
File.write('thumbnail.jpg', jpeg_data)

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
