// SNIPPET NAME: JWPlayer
// SNIPPET DESCRIPTION: A Snippet to place the JW FLV Player into a MODx Page
// VERSION 1.1

/*---------------------------------
================
:: CREDIT
================

  This Snippet writes the code necessary to properly display the JW FLV player in MODx
  THE JW FLV player is developed by Jeroen Wijering and is available at http://www.jeroenwijering.com/

================
:: INSTALL
================

  - Download the .zip at http://www.jeroenwijering.com/?item=JW_FLV_Player
  - Unzip the file  and rename it 'embed'
  - Place /embed/ inside another directory entitled 'JWPlayer'
  - Upload the JWPlayer directory to your assets/snippets/ directory
  - Paste the text of this document in a snippet - entitled 'JWPlayer'
  
  - Reccommended: Create a Templave Variable (TV) Called 'videosrc' and
    Set the input type as 'file'
  
  * I'm not packaging these files in the snippet download - because the player is 
    sometimes updated - and you probably want the newest one.

  * Tested and written for JW FLV MEDIA PLAYER v. 4.0

================
:: USAGE
================

  - Simple! Place the snippet call [[JWPlayer? &src=[*videosrc*]]] in your document.
  - If you chose to create the TV above, use the call [[JWPlayer? &src=[*videosrc*]]]
    and set the filename using the TV dialog in your document.
  - If you choose to use paramaters, simply append them like so: 
    [[JWPlayer? &src=[*videosrc*]&parameter1=value1&parameter2=value2&]]
    (kind-of like a URL line, but make sure there's a space between the ? and the &.)
  - If you use the player more than once in a page with different sources, scrap the TV and do this:
    [[JWPlayer? &src=path/to/file]]

================
:: AVAILABLE PARAMETERS
================

  *- All of these parameters defaults are editable below

  &width - width in px
  &height - height in px
  &logo - location of logo from MODx install root. (ex: assets/images/monkeys/logo.png )
  &fullscreen - enables fullscreen function ( true | false )
  &stretching - specifies stretch type (uniform | fill | exactfit | none )
      -'uniform' plays the video and fills up the frame - using black bars to perserve aspect
      -'fill' fills up the frame while maintaining aspect ratio - may result in clipping.
      -'exactfit' stretches the movie to fit the frame - aspect ratio is out the window
      -'none' doesn't stretch at all - just plays the video in it's original dimensions. 
        Clipping possible.
  &controlbar - displays controlbar either as a floaty transparent thing, or the traditional
   bottom ( float | over | none )

================
:: FORMATS
================

Baseline h.264. The player isn't too picky about the file extension - I use .mp4, but I tested it with .flv and .m4v.
To be kind, stick to about 600/700 mb/sec or less.
