WordPress.org

It's pretty simple to install. Just follow the common intention:

1. Unzip the plugin file, it will create a directory named proplayer
2. Upload the directory to the /wp-content/plugins/ directory
3. Activate the plugin through the 'Plugins' menu in WordPress

That's it. The usage is like this:

    [pro-player]http://www.youtube.com/watch?v=2YAvfxA6a94[/pro-player] 
    [pro-player width="500" height="500"]http://vimeo.com/1473498[/pro-player]
    [pro-player type="mp4"]http://www.mydomain.com/media/awesome.mp4[/pro-player]

If you're a template developer or you want to show a video in a fixed position in the site:

    <?php 
        print insert_proplayer(
             array(
                "width" => "530",
                "height" => "213",
                "playlist" => "bottom"
             ),
             "http://www.youtube.com/watch?v=2YAvfxA6a94"
        ); 
    ?>
