ofl - Open Flash CLI Application for SWF files

ofl is a command line application to process SWF files using the libraries of the Open Flash project. The current subcommands allow to parse an SWF file, extract its content and analyze its AVM1 buffers.

This project is part of the Open Flash project.

Installation

cargo install --git https://github.com/open-flash/ofl

Commands

dump

ofl dump [FLAGS] <swf> [output]

Extract all the data from the provided SWF file into an output directory.

This command generates the following files inside the output directory:

• movie.json: full Movie
• header.json: Header
• <tagIndex>/tag.json: Tag

For tags containing AVM1 buffers (such as DoAction), it also generates the following files:

• main.avm1: AVM1 buffer
• main.cfg.json: Parsed Control Flow Graph

This is the recommended command to quickly analyze a SWF file.

parse

ofl parse movie.swf

Parses an SWF file and into an swf-types Movie and prints it as JSON.
