RSS parser work principle

In order for the EX.CO parser to support your RSS feed you need to know a few simple principles of how we get content to generate a video

Supported feed tags are (all of these tags should be under the <channel <item>REQUIRED_TAGS_HERE</item> </channel> tag):

Tag	Description	Required
`<title>`	Will be used as scene title	true
`<link>`	Will be used to access web page and parse content from html	true
`<category>`	Specifies one or more categories item belongs to.	false
`<enclosure>` or `<content:encoded>`	Will be used to get media content form it (images only supporter at this moment)	false
`<isoDate>` or `<pubDate>`	Will be used to include topic creation date to the scene	false
`<author>` or `<dc:creator>`	Will be used to include topic author to the scene	false
`<media:content>` and `<media:group>` more details	Will be used to get media content form it (images only supporter at this moment)	false

2. In case of required values - title, image can't be fetched from the feed, parser will try to grab content from the <link> tag link, and extract information from the web page. Parser will search for the content in the next html tags:

Tag	Description	Examples
`<meta property="og:image" content="" />`	An image for a video scene	`<meta property="og:image" content="http://site.com/images/example.jpg" />`
Any `<address>`, `<a>`, `<link>` with a `class` or `rel` attributes with `author value`	An image for a video scene	`<a herf="http://test.com" class="author">Author Name</a>`
You can find an example of a valid feed and page(s) under this link

Good to know

Supported image formats are JPEG (.jpg, .jpeg) and PNG (.png)
Scenes order in video based on <pubDate> or <isoDate> tag(s), ordered from newest to oldest. In case if those tags are not exist, scenes will be built in order <item> appear in feed, from top to bottom.
Parser sends requests with User-Agent: Playbuzz RSS parser header, in case if page is not available, we retry with an empty User-Agent header
Timeout for a request to RSS link and any link under <link> tag is 20s
Parser does not support any kind of authorizations and/or authentications
Parser support 301 redirects
In order to build a correct scene all media (images) content should be available for a direct download without any restrictions
