' Event notification script for ReClock
' -------------------------------------
'
' This script will be called when ReClock change the media adaptation of a played file
' either automatically or after some manual change made in the properties panel
' It is called only for media file which contain a video stream, and when frame rate of this file is known
'
' ---------------------------------------------------------------------------------------------
' The 7 parameters received by this script are explained below:
'
' (1) contains the event name that just occurred:
'    - "GREEN"  : tray icon just got green (all is fine). Parameter
'    - "YELLOW" : tray icon just got yellow. We should make what is necessary
'                 to change the monitor refresh rate 
'    - "STOP"   : playback just stopped
'    - "QUIT"   : ReClock is about to quit
'
' Parameters (2), (3), (8) and (9) apply only with "GREEN" and "YELLOW" events. Otherwise they contain "-"
'
' (2) contains the type of media file currently played :
'    - "CINEMA" : frame rate of source file is around 24 fps
'    - "PAL"    : frame rate of source file is around 25 fps
'    - "NTSC"   : frame rate of source file is around 30 fps
'    - "CUSTOM" : frame rate of source file does not fall in previous categories
'
' (3) contains the current sound playback mode (apply only with GREEN/YELLOW event):
'    - "PCM"    : PCM mode
'    - "SPDIF"  : AC3 passthrough SPDIF
'
' (4) contains the current monitor selected for playback (1=primary, 2=secondary, etc...)
'
' (5) contains the total monitor count detected in the system
'
' (6) contains the current resolution of your monitor (WIDTHxHEIGHT)
'
' (7) contains the current refresh rate of your monitor (in Hz)
'
' (8) contains the original playback rate of the file (in fps multiplied by 1000)
'
' (9) contains the current playback rate of the file (in fps multiplied by 1000)
'
' (10) contains the filename of the current media file
'
' ---------------------------------------------------------------------------------------------
' Notifications examples:
'   - GREEN CINEMA PCM 1 1 1024x768 72 23976 24000 c:\test.avi : all is good
'   - GREEN NTSC PCM 1 1 1024x768 60 29970 30000  c:\test.avi : all is good
'   - YELLOW PAL SPDIF 1 1 1024x768 72 25000 25000 c:\test.avi : please switch to a multiple of 25 hz since PAL 

wants 25 fps
'   - YELLOW CINEMA SPDIF 1 1 1024x768 75 23976 23976 c:\test.avi : please switch to 71.928 hz

' Here is a sample in VbScript that will call Powerstrip to change the monitor refresh rate

' them to the clipboard)

' forget to notify Windows applications it did that (including ReClock). So this script MUST exit with
' an exit code of 0 if it did change the configuration with powerstrip. Otherwise the script should
