9% INPUT:
10% FileName: input file name
11%                 other inputs needed  only for video and multi-image file:
12% FileType: input file type, as determined by the function get_file_info.m
13% VideoObject: video object (for faster reading if availlable)
14% num: frame index for movies or multimage types
