The standard WordPress Thickbox can size images dynamically to fit the user’s browser window. But what about video or other types of media. 
This plugin allows any content to be shown in a thickbox that is sized dynamically to fit the browsers window. While a popup can be initiated 
from a link like the standard Thickbox, the plugin is intended to be used as a shortcode because more options to control the display can be supported. 
A shortcode builder form is provided so you don’t need to remember all options can get the names right.

ILC FLVBox will parse your post content looking for links to FLV videos. When found, it will add a player to play it inline or in a modal dialog.
The modal dialog is currently handled by ThickBox, which requires jQuery. Both Thickbox and jQuery are loaded from the versions included with WordPress using wp_enqueue_script.

The FLV players included are:
http://miplayweb.com/player/ 
 
http://osflv.com/
The player embedding uses SWFObject 1.5 (sometimes IE6 doesn’t get along nice with SWFObject 2.1 dynamic publishing, as soon as this is sorted out the SWFObject included will be upgraded).

This software is provided without warranty of any kind.
There’s an option page with an option to select an FLV Player. You can choose here your player, MiPlayWeb or OSFLV. If you select OSFLV more options are unfolded (background and foreground colors, initial volume level). Flowplayer player will be added later to the list of optional players.
When you check the box enabling ThickBox, a textarea is unfolded containing an CSS file that will allow you to set the style of the inline image. You can also edit this file independently on your editor of choice, by opening the flvbox.css file. If Thickbox is in use, the player is set to autoplay, so when you click on the image launching the player, the video will start inmediately.
The FLVBox dimensions option sets the size of the player (indirectly, the video, but not specifically). The ThickBox area is adjusted accordingly.
There’s one last field in case you need to rename the folder or change the path of ILC_FLVBox. 
Both Thickbox and jQuery are loaded from the versions included with WordPress using wp_enqueue_script.
