Usage

Note for YouTube and Vimeo usage!

Youtube and Vimeo have recently updated their APIs to require API keys.

Scrapers has been implemented for both Youtube and Vimeo. However, the Youtube scraper can only get the date the video was posted, while the API is able to get the date and the exact time the video was posted. You may also wish to use the API to protect against potential HTML changes that could break the scrapers.

How to get these API keys

To get a Youtube API key, follow the instructions here. After generating a Youtube API key it is necessary to enable the YouTube Data API for the project which your API key was generated enable Youtube Data API here.
To get a Vimeo API key, follow the instructions here.

To set the API keys, do the following:

VideoInfo.provider_api_keys = { youtube: 'YOUR_YOUTUBE_API_KEY', vimeo: 'YOUR_VIMEO_API_KEY' }

You can also use the valid_url? helper to check if a given url is valid in some of the enabled providers:

> VideoInfo.valid_url?('http://www.youtube.com/watch?v=AT_5xOGh6Ko')
=> true
> VideoInfo.valid_url?('http://vimeo.com/898029')
=> true
> VideoInfo.valid_url?('http://www.example.com/video/12345')
=> false

Options

video = VideoInfo.new('http://www.youtube.com/watch?v=mZqGqE0D0n4', 'User-Agent' => 'My YouTube Mashup Robot/1.0')
video = VideoInfo.new('http://www.youtube.com/watch?v=mZqGqE0D0n4', 'Referer'    => 'http://my-youtube-mashup.com/')
video = VideoInfo.new('http://www.youtube.com/watch?v=mZqGqE0D0n4', 'Referer'    => 'http://my-youtube-mashup.com/',
                                                                    'User-Agent' => 'My YouTube Mashup Robot/1.0')

You can also use symbols instead of strings (any non-word (/[^a-z]/i) character would be converted to hyphen).

video = VideoInfo.new('http://www.youtube.com/watch?v=mZqGqE0D0n4', referer: 'http://my-youtube-mashup.com/',
                                                                    user_agent: 'My YouTube Mashup Robot/1.0')

User-Agent when empty defaults to "VideoInfo/VERSION" - where version is current VideoInfo version, e.g. "VideoInfo/0.2.7".

It supports all OpenURI header fields (options), for more information see: OpenURI docs.

You can also include an iframe_attributes or url_attributes hash to the embed_code method to include arbitrary attributes in the iframe embed code or as additional URL params:

VideoInfo.new('http://www.youtube.com/watch?v=mZqGqE0D0n4').embed_code(iframe_attributes: { width: 800, height: 600, 'data-key' => 'value' })
=> '<iframe src="//www.youtube.com/embed/mZqGqE0D0n4" frameborder="0" allowfullscreen="allowfullscreen" width="800" height="600" data-key="value"></iframe>'

VideoInfo.new('http://www.youtube.com/watch?v=mZqGqE0D0n4').embed_code(url_attributes: { autoplay: 1 })
=> '<iframe src="//www.youtube.com/embed/mZqGqE0D0n4?autoplay=1" frameborder="0" allowfullscreen="allowfullscreen"></iframe>'

If you would like to disable certain providers, you can do so by modifying the class variable disable_providers:

VideoInfo.disable_providers = %w[YouTube] # disable YouTube
VideoInfo.disable_providers = %w[Vimeo YouTube] # disable Vimeo and Youtube
VideoInfo.disable_providers = [] # enable all providers

NOTE: disable_providers is case-insensitive. Attempting to use a disabled provider will raise a UrlError, just like attempting to use a non-video URL.
