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>
Here’s a link to <a href="https://wordpress.org/" title="Your favorite software" rel="ugc">WordPress</a> and one to <a href="http://daringfireball.net/projects/markdown/syntax" title="Markdown is what the parser uses to process much of the readme file" rel="nofollow ugc">Markdown’s Syntax Documentation</a>. 
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>

This plugin enhances page load times by loading only the YouTube video preview image initially. Additionally, it offers the option to make your video sticky, positioning it at the top or bottom of the window when the user scrolls away from the video viewport.
<h3>Features</h3>
<ul>
<li>Lazy Load Videos: Reduce the amount of time it takes to load your video by loading just the video thumbnail.</li>
<li>Multiple Video Support: You may quickly and simply add more than one video to a page. Videos can only be played one at a time, and when one is playing, the other one instantly pauses.</li>
<li>Sticky Video: Keep videos visible as you navigate by adhering them to the top or bottom of the screen to ensure ongoing playback.</li>
<li>Custom Styling: Adapt your videos’ look to perfectly match the style of your website by using your own CSS.</li>
</ul>
