 Description:
 ============
 The supported scripts are written to demonstrate the various functions of the codec firmware such as 
 encoding, decoding and also some of the datapaths available.
 Each supported script has various configuration parameters and it is REQUIRED that the format of a 
 supported script follow a common convention. 
 The convention consist of a description of the supported script, followed by the definition of various 
 configuration parameters and then the script itself.
 
 CONFIGURATION OF FORMAL PARAMETERS:
 ===================================
 
 Format:  PARAMETER = PARAMETER or DefaultValue
 example: VIN   	= VIN or "svideo"
 
 This allows to change the configuration of a script by specifying actual parameter on the command line in the form:
 
 mobiapp -e 'VIN="svideo"; VOUT="svideo"' -f <script name>

CONFIGURATION PARAMETER NAMING CONVENTION
=========================================

PARAM								DESCRIPTION                					VALUES		
=====       						======================     					======       
VIN									Video Input mode           					hdmi, component, svideo, composite
VOUT								Video Output mode          					hdmi, component, svideo, composite
FORMAT      						Video format               					480i, 720p, 1080i 
VBITRATE							Video bitrate			   					6000000
ABITRATE							Audio bitrate			   					64000

BITSTREAM_OUTPUT					Debug variable to disable					1																			1
									bitstream output to host
									1 = enable, 0 = disable
GOP_STRUCTURE						Controls the GOP structure					IP
 									"IBBRBP" : Pyramidal GOP structure
 									"IP" : No B frames	
							
FRAME_STRUCTURE						Controls the coding structure of a 			mbaff
									frame or field pair
									"mbaff" : mb adaptive field/frame
									"field" : field coding
									"frame" : frame coding.
									
PREVIEW								Controls live vs reconstructed preview		2
									 0 : no preview
									 1 : live
									 2 : reconstructed

FILENAME                            Sets the destination filename if using a    /path/to/file
                                    storage bitstream writer.  It is set to
                                    /dev/null by default.
 
FRAMERATE                           Overrides the default framerate of the      30, 15, 60 etc.
                                    video system.  If not specified it uses
                                    the video system frame rate.  Note that
                                    the difference between 29.97 and 30 is
                                    taken into account in the script so
                                    specifying 30 for NTSC or 1080i is 
                                    equivalent to 29.97.

MAXNALULEN                          Specifies the maximum NALU length, or       0, 1472 etc.
                                    0 by default.
