How do I... Create a page of videos from an RSS feed such as 12seconds.tv?

You can use a DekiScript to fetch the RSS feed of a video service and then dynamically create <embed> and/or <object> tags to show the them in a page when their title contains a specific keyword.

First: let's create a template for our purposes; we are calling the template "VideoFeed12SecondsTV".

<div block="var title = xml.text(item['title']); var link = uri.parse(xml.text(item, 'link')); var id = link.path[#link.path - 1]" init="var feed = $0 ?? $feed ?? 'http://12seconds.tv/channel/sarahmcarr/feed'; var keyword = $1 ?? $keyword ?? 'mindtouch'; var rss = web.xml(feed)" where="string.contains(xml.text(item['title']), keyword, true)" foreach="var item in rss['channel/item']">
<h2>{{ title }}</h2>
<object width="430" height="360" type="application/x-shockwave-flash" data="http://embed.12seconds.tv/players/remotePlayer.swf">
<param name="movie" value="http://embed.12seconds.tv/players/remotePlayer.swf" />
<param name="FlashVars" value="{{ 'vid=' .. id }}" /> <embed width="430" height="360" src="http://embed.12seconds.tv/players/remotePlayer.swf" flashvars="{{ 'vid=' .. id }}"></embed></object></div>

Notice on this template we're passing in the source feed as the first parameter and the keyword to match as the second parameter.

Next: Use the template.

{{ template.VideoFeed12SecondsTV("http://12seconds.tv/channel/sarahmcarr/feed", "mindtouch") }}

And see the output:
