FormatParser

FormatParser can be used to figure out the type and the format of a file. It also can extract some additional information.

Documentation can be found here.

Inspired heavily by format_parser.

Basic usage

# Image
{:ok, file} = File.read("myimage.png")
match = FormatParser.parse(file)
match.nature                      #=> :image
match.format                      #=> :gif
match.width_px                    #=> 256

match.intrinsics[:filter_method]  #=> 0

# Video
{:ok, file} = File.read("myvideo.flv")
match = FormatParser.parse(file)
