SWF metadata parser

This is an Erlang port of the hexagonit.swfheader package which is a SWF metadata parser for Python.

Usage

The module exposes two functions. parse/1 parses the the given SWF file and returns the metadata in a tuple. print_header/1 pretty prints the metadata in stdout.

You can use the parse/1 function in your own code in the following way:

{version, Version,
 compression, Compression,
 width, Width,
 height, Height,
 bbox, {xmin, Xmin, xmax, Xmax, ymin, Ymin, ymax, Ymax},
 frames, Frames,
 fps, Fps} = swfheader:parse("/path/to/the/file.swf").

All items have numeric values except compression which is either the atom compressed or uncompressed.

The print_header/1 function can be used directly from the command line to quickly inspect the metadata in an SWF file, e.g.:

$ erl -pa -s swfheader print_header /path/to/the/file.swf -s init stop -noshell

This will print the following to stdout:

Version: 5
Compression: uncompressed
Dimensions: 550.0 x 400.0
Bounding box: (0.0, 550.0, 0.0, 400.0)
Frames: 3072
FPS: 1

The exact values will naturally depend on the particular SWF file.
