[FFmpeg-user] ScaleUp the Raw file

This example works for me:

rem  Make a RAW image:
ffmpeg -f lavfi -i testsrc2=s=320x200 -pixel_format gray10be -frames 1 
-f rawvideo -y raw.raw

rem  The file raw.raw contains exactly 320 x 200 x 2 = 128000 bytes
rem  It doesn't contain any information about width, height and pixel 
format.

rem  Convert the RAW image to JPG:
ffmpeg -s 320x200 -pixel_format gray10be -f rawvideo -i raw.raw -y out.jpg
