Video Demo
{formatORprovider}filenameORvideoID{/formatORprovider}
You can also use syntax like: {format/provider}filenameORvideoID|width|height|autoplay{/format/provider}
...where "width" and "height" are the media dimensions in pixels and "autoplay" is enabled using 1 (use 0 to disable it).
For example, a YouTube video with 600x450 dimensions that autoplays on page load would be displayed adding this plugin tag in your Joomla! article (or K2 item, or Virtuemart product etc.): {youtube}he73js822|600|450|1{/youtube}
