How to run:
-----------
Note: There are two functions "Encode then Decode" and "Decode Only":

1. Encode then Decode: ( decoder default disable down-scale )
Usage:  ./ijg_jpeg_demo arg1 arg2 arg3 arg4 arg5
Options:
argv1:  output JPEG filename, like "my_jpeg.jpg" or others
argv2:  compress quality, like "75", 0 (worst) ~ 100 (best)
argv3:  input raw filename, like "for_hw_yuv422_480x272.bin" or others
argv4:  input raw width, like "480" or others
argv5:  input raw height, like "272" or others


2. Decode Only:
Usage:  ./ijg_jpeg_demo arg1 arg2
Option:
argv1:  input JPEG filename, like "my_jpeg.jpg" or others
argv2:	enable scale down or not, like "1": enable, "0": disable

Test Pattern:
-------------
1. /decode_pattern
Normal.jpg				--> For Hardware and Software Decoder
NoHuffmanTable.jpg		--> For Hardware Decoder Only
Progressive.jpg			--> For Auto Switch to Software Decoder ( if hardware decode is failed )
Normal_640x480.jpg		--> For Hardware and Software Decoder
Normal_1000x1000.jpg	--> For Hardware and Software Decoder

2. /encode_pattern
for_hw_yuv422_480x272.bin	--> Hardware Encoder Pattern
for_hw_yuv422_500x500.bin	--> Hardware Encoder Pattern
for_hw_yuv422_640x480.bin	--> Hardware Encoder Pattern
