/*
The following script detects the mediaplugins for using media in objects/embed webpage and if found
send a link to the player script and play the file.
Use this script by calling the "play()" commando in the file where this javascriptfile is included

Usage:

The play()commando:
play(file,players_list,controls)
file            = name of the mediafile to use
players_list    = which mediaplayers to use for this object in the desired order
controls        = properties of the mediaplayers

example:
play("movie4.wmv","mediaplayer,quicktime,real","controls=true&display=true&statusbar=true&autostart=true&tracker=false&loop=false")

Controls:
controls=true or false
display=true or false
statusbar=true or false
autostart=true or false
tracker=true or false
loop=true or false
