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>

Livestream Embedder allows you to embed a live stream from a YouTube channel or the most recent video using a shortcode. You can configure the API key and channel ID via the plugin’s settings page.
Features: 
* Embed a live stream or most recent video with a shortcode. 
* Configure the YouTube Data API key and default channel ID via settings. 
* Display error messages if no live stream is available. 
* Responsive video embeds.
Note on External Services: 
This plugin uses the YouTube iframe API and YouTube Data API to fetch video data from YouTube and display it. Users must provide their own YouTube API key, which is required to make requests to the YouTube Data API v3. The data requested includes information about the live streams or videos on a given YouTube channel.
By using this plugin, you agree to YouTube’s <a href="https://www.youtube.com/t/terms" rel="nofollow ugc">Terms of Service</a> and <a href="https://policies.google.com/privacy" rel="nofollow ugc">Privacy Policy</a>.
Shortcode Usage:
<ol>
<li>
To embed a live stream from a specific channel: 
 [livestream_embedder channel_id=”CHANNEL_ID”]
Replace <code>CHANNEL_ID</code> with the actual YouTube channel ID (e.g. <code>UCabcdefghijklmnopqrstuvwx</code>).
</li>
<li>
If you’ve configured a default channel ID in the plugin settings, you can use the shortcode without the <code>channel_id</code> attribute: 
 [livestream_embedder]
</li>
</ol>
How to Find the Channel ID:
<ol>
<li>Go to the YouTube channel’s page.</li>
<li>Look at the URL in your browser’s address bar. The channel ID is the string of characters after the “/channel/” part of the URL.</li>
<li>If the channel uses a custom URL, you can find the channel ID by viewing the page source and searching for “channelId”.</li>
</ol>
