# VideoBlur

Video_blur is a small ruby gem to blur a part of a video using FFmpeg. It automates the aspect ratio conversion and the FFmpeg filter parameters.

## Requirements :

[FFmpeg](https://www.ffmpeg.org/) must be installed. To ensure it is available, on your command line, run `which ffmpeg`.

This will give you the path where ffmpeg is installed. For example, it might return `/usr/local/bin/ffmpeg`.

Install FFmpeg on OS X : ``` brew install ffmpeg ``` 

Install FFmpeg on Linux : ``` apt-get install ffmpeg ffmpeg ``` 

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'video_blur'

```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install video_blur

## Usage

Example : Blur the video in.mp4 starting at (x=200, y=160) with blur box size (width=145, height=360)

    

    video_blur in.mp4 -x 200 -y 160 -w 145 -e 360 -o out.mp4
