Video Preview

This little library allows you to generate video previews in a wise manner. Specifically, it picks N frames from a video and then ranks them by the contrast ratio of an image.

To install it, simply run gem install video-preview. The library has two main dependencies: ffmpeg and imagemagick. Make sure you have them as well.

Here's an example on how to use it:

require 'video-preview'
VideoPreview.get_preview 'trailer.mp4'
# => #<Magick::Image:0x007fd5738869b8>
