This plugin allows you to create internal <code><a></code> links within your content that will not break when things get renamed or moved. While there are similar plugins available, they do not offer important SEO options.
You can add any HTML attribute to your link as long as it’s prefixed with “attr_”. And because it supports attributes that may not currently exist, it is future proof.
Examples:
<ol>
<li>Link to a post/page by ID or slug
<ul>
<li>Shortcode: <code>[link id="1234"/]</code></li>
<li>Shortcode: <code>[link slug="post-slug"/]</code></li>
<li>Output: <code><a href="http://domain.com/post-slug/">Post Title</a></code></li>
</ul>
</li>
<li>Link to a category by slug
<ul>
<li>Shortcode: <code>[link cat="cat-slug"/]</code></li>
<li>Output: <code><a href="http://domain.com/cat-slug/">Category Name</a></code></li>
</ul>
</li>
<li>Link to a tag by slug
<ul>
<li>Shortcode: <code>[link tag="tag-slug"/]</code></li>
<li>Output: <code><a href="http://domain.com/tag-slug/">Tag Name</a></code></li>
</ul>
</li>
<li>Custom text instead of retrieved title
<ul>
<li>Shortcode: <code>[link id="1234"]custom text[/link]</code></li>
<li>Output: <code><a href="http://domain.com/post-slug/">custom text</a></code></li>
</ul>
</li>
<li>Additional attributes for SEO/other
<ul>
<li>Shortcode: <code>[link id="1234" attr_rel="something" attr_itemprop="specialty"/]</code></li>
<li>Output: <code><a href="http://domain.com/post-slug/" rel="something" itemprop="specialty">Post Title</a></code></li>
</ul>
</li>
</ol>

<h4>Usage</h4>
In order to embed a video, create a new post/page and use the following shortcode:
<pre><code>[flowplayer src="http://example.com/wp-content/uploads/videos/test.mp4"]
</code></pre>
here, src is the actual source of your mp4 video file.
In addition to the source mp4 video file, you can also specify a webm video file. This step is optional since mp4 video format is supported by almost all major browsers.
<pre><code>[flowplayer src="http://example.com/wp-content/uploads/videos/test.mp4" webm="http://example.com/wp-content/uploads/videos/test.webm"]
</code></pre>
Poster Image
If you want to show an image as placeholder before the video plays, you can specify it in the “poster” parameter:
<pre><code>[flowplayer src="http://example.com/wp-content/uploads/videos/test.mp4" poster="http://example.com/wp-content/uploads/images/poster.jpg"]
</code></pre>
Autoplay Video
If you want a particular video to start playing when the page loads you can set the “autoplay” option to “true”:
<pre><code>[flowplayer src="http://example.com/wp-content/uploads/videos/test.mp4" autoplay="true"]
</code></pre>
Player Size
By default, the player takes up the full width of the content area. You can easily control the size by specifying a width for it:
<pre><code>[flowplayer src="http://example.com/wp-content/uploads/videos/test.mp4" width="500"]
</code></pre>
The height will be automatically determined based on the ratio (please see the “Control Player Ratio section” for details).
Player Ratio
The player ratio is set to “0.417” by default. But you can override it by specifying a different ratio in the shortcode:
<pre><code>[flowplayer src="http://example.com/wp-content/uploads/videos/test.mp4" ratio="0.345"]
</code></pre>
Loop Video
If you want a particular video to start playing again when it ends you can set the “loop” option to “true”:
<pre><code>[flowplayer src="http://example.com/wp-content/uploads/videos/test.mp4" loop="true"]
</code></pre>
