Oh, sorry, I just realize the default powerpress player just uses the audio tag so the player is the browser’s. You have nothing to do with it. My apology.

This turned out pretty straightforward, as wordpress API makes it easy. Posting code here. Hope this’ll help someone.

<?php

/*
    Postie add-on to extract [enclosure] short code and insert into meta table the way powerpress does it
    Take, for example,
        [enclosure type="audio/mpeg" url="http://feeds.soundcloud.com/stream/9966888"
                length="854664" duration="00:23:11"]/>
    and add_post_meta 'enclosure' with value

    http://feeds.soundcloud.com/stream/9966888
    854664
    audio/mpeg
    a:1:{s:8:"duration";s:8:"00:23:11";}

*/

$enclosure = '';

function extract_enclosure($post) {
    //do something here like update $post['post_content']
    global $enclosure;

    // look for a line containing
    // [enclosure ....]
    //
    // may have spaces or > before and spaces after, but must be on line by itself
    $re = '/(\R+|^)[ >]*\[enclosure (.+)?\] *(\R+|$)/m';

    if (preg_match($re, $post['post_content'], $m)) {
        // use SimpleXMLElement to parse attribute
        $xml = new SimpleXMLElement("<element {$m[2]} />");
        if ($xml) {
            $enclosure =
                $xml[0]['url'] . "\n" .
                $xml[0]['length'] . "\n" .
                $xml[0]['type'] . "\n" .
                'a:1:{s:8:"duration";s:8:"' . $xml[0]['duration'] . '";}';
        }
        // replace multiple preceding and trailing \n with 1
        $nl = $m[1] ? "\n" : '';
        $nl .= $m[2] ? "\n" : '';
        $post['post_content'] = preg_replace($re,  $nl, $post['post_content'], 1);
    }
    return $post;
}

function insert_enclosure($post) {
    global $enclosure;

    if ($enclosure) {
        add_post_meta($post['ID'], 'enclosure', $enclosure, true);
    }
    return $post;
}

add_filter('postie_post_before', 'extract_enclosure');
add_filter('postie_post_after', 'insert_enclosure');

?>

Thank you, but I think I went down the wrong path with the [powerpress] shortcode, since that only affects what shows up visually, ie, it will show a media player in the post.

What I need is to be able to attach a URL to a media file so that it will show up in the feed as an RSS enclosure and be recognized as a podcast episode.

Internally, this isn’t in the post table, but the postmeta table with meta_key ‘enclosure’
