Gives you a shortcode for Youtube-Videos and makes a preview-pic for this Video and realizes to watch the video with fancybox for wordpress oder prettyPhoto or in a extra tab. You choose, what you want.
The URL ist for example: http://www.youtube.com/watch?v=XmRLJ4XvpZk 
The shortcode is
<pre><code>[ytcode ytid="XmRLJ4XvpZk"]
[ytcode ytid="XmRLJ4XvpZk" tit="Vemma Strategie Deutsch"]
[ytcode ytid="XmRLJ4XvpZk" tit="Vemma Strategie Deutsch" x="800" y="488"]
[ytcode ytid="XmRLJ4XvpZk" x="800" y="488" ppic="2"]
[ytcode ytid="XmRLJ4XvpZk" ppic="default"]
[ytcode ytid="XmRLJ4XvpZk" fso="v"]
</code></pre>
<ul>
<li>Options:</li>
<li>
float=”left|none|right” 
if float is none, you can choose the alignment:
</li>
<li>
align=”left|center|right”
</li>
<li>
fso=”h|v|n” 
horizontal, vertical, none filmstripes
</li>
<li>
ppic=”default|1|2|3″ 
takes the previewpic from youtube. This are the four possible picture-names.
</li>
<li>
vb=”prettyphoto|fancybox|blank” 
if installed it uses prettyphoto or fancybox. Or it opens the video in a new tab (target=”_blank”)
</li>
<li>
pfeil=”FF0000″ 
the color of the arrow is now red
</li>
</ul>
<h3>Arbitrary section</h3>
*Known Issues: 
 – Publishing an Artikel/Site or update ist can cause an error-message “Warning: Cannot modify header information – headers already sent by (…)” 
 maybe this is theme specific or it depends to other plugins!
<h3>A brief Markdown Example</h3>
Unordered list:
<ul>
<li>Make opacity from the overlay-pic with the arrow on the preview-pic adjustable</li>
<li>resizing of the previewpic doesn’t work correct!</li>
</ul>

Titles are optional, naturally.
Markdown uses email style notation for blockquotes and I’ve been told:
<blockquote>
Asterisks for emphasis. Double it up for strong.
</blockquote>
<pre><code><?php code(); // goes in backticks ?>
</code></pre>

Makes a preview-pic out of the short youtube-id, uses fancybox or prettyPhoto

Le-Pixel-Solitaire

The “Enhanced YouTube Shortcode” plugin provides a quick & easy way to use a custom YouTube© player in your posts and/or pages without having to get your hands dirty in the source codes! The main advantage over the way WordPress is working this out is the possibility of changing the display of all players in one single spot instead of having to do it manually at every places it has been set. But most importantly: it’s fun and good for you! (check out the screenshot for a sample of all offered options!)
Now with more than 10 parameters available through a simple configuration page (reach it from the Settings Menu), the code that is generated always allows scripting access and forces the use of the ActionScript 3 engine (see Other Notes for limitations). It has been initially created on a WordPress 3.2.1 live installation & recently tested on a WordPress 3.9.1 live installation with success, according to the specifications of the official <a href="http://code.google.com/intl/fr-CA/apis/youtube/player_parameters.html" title="YouTube Embedded Player Parameters - Google Code" rel="nofollow ugc">YouTube Embed Player API Parameters</a>.
There are a couple of things on the To Do list (see Other Notes) & the developer is back on track with this project so you can expect a major upgrade soon (summer 2014)!
<h3>Limitations</h3>
<ul>
<li>
Internet Explorer is not a natural friend of YouTube… Every versions of this browser, from 6 all the way up to 9, have different bugs & even more ways to deal with YouTube videos. So in order to push a video to everyone this plugin will provide a player to Internet Explorer effectively but without other parameters than width & height. All the rest will be the default state of a “regular” YouTube video player. A future version should solve those issues by serving an all javascript player to this browser.
</li>
<li>
The tests on WordPress 3.9.1 were quick, some features may be not working but this should not affect the plugin responsiveness. All bases will be covered in the next major release of the plugin (v3).
</li>
<li>
Some WordPress themes that already have a bunch of shortcodes may cause conflicts with this one. Usually a quick look in the doc of your theme & you’ll find a way of injecting “raw” codes in your post without triggering any presets options.
</li>
</ul>
<h3>TO DO</h3>
In the plan for the next major upgrade (v3) :
<ul>
<li>
Rewrite the core of the display functions.
</li>
<li>
A simpler/quicker way of inserting the shortcode.
</li>
<li>
HTML5 implementation.
</li>
</ul>
In the back of my mind…
<ul>
<li>
Develop some «height & width» presets.
</li>
<li>
Google Analytics integration.
</li>
<li>
Take over the world.
</li>
</ul>
Not necessarily in that order…
