In PowerPress 2.0 we introduced a filter that Themes can use to add their own links in the media links section. Here's an example that adds a Subscribe to iTunes link:
Add the following function to your Theme's functions.php:
function themename_powerpress_player_links($content, $media_url, $ExtraData = array())
{
$content .= ' '.POWERPRESS_LINK_SEPARATOR .' ';
$content .= 'Subscribe: <a href="http://itunes.apple.com/us/podcast/tech-news-weekly/id393765696">iTunes</a>';
$content .= ', <a href="http://social.zune.net/podcast/Tech-News-Weekly-Audio/0a83101d-b633-40e2-a68a-167b974beb4d">Zune</a>';
$content .= ', <a href="http://fusion.google.com/add?feedurl=http://feeds.feedburner.com/TechNewsWeeklypodcast">Google</a>';
return $content;
}
add_filter('powerpress_player_links', 'themename_powerpress_player_links', 100, 3);
The 2nd parameter is the media URL in question, and the third parameter $ExtraData is an associative array of extra meta data about the media file including 'type', 'length' (file size in bytes), and other iTunes attributes.
