Shumway is an HTML5 technology experiment that explores building a faithful and efficient renderer for the SWF file format without native code assistance.
A short explanation of SWF:
The SWF file format delivers vector graphics, text, video, and sound over the Internet and is supported by Adobe Flash Player and Adobe AIR software. Flash Player already reaches over 98% of Internet-enabled desktops and more than 800 million handsets and mobile devices.
The SWF file format is designed to be an efficient binary delivery format, not a format for exchanging graphics between graphics editors.
SWF File Format Specification (version 10)
The SWF file format is available as an open specification to create products and technology that implement the specification. SWF 9 introduced the ActionScript 3 language and virtual machine. The SWF 10 specification expands text capabilities with support for bidirectional text and complex scripts with the new DefineFont4 tag. The DefineBitsJPEG4 tag allows embedding JPEG images that have an alpha channel for opacity and also a smoothing filter. SWF 10 also adds support for the free and open-source Speex voice codec and for higher frequencies in the existing Nellymoser codec.

The story ...
Shumway is an experimental web-native runtime implementation of the SWF file format. It is developed as a free and open source project sponsored by Mozilla Research. The project has two main goals:
1. Advance the open web platform to securely process rich media formats that were previously only available in closed and proprietary implementations.
2. Offer a runtime processor for SWF and other rich media formats on platforms for which runtime implementations are not available.
You can view live demo examples using Shumway. More adventurous users can download a Firefox beta build and install the test extension to preview SWF content on the web using Shumway. Please be aware that Shumway is very experimental, is missing features, contains many defects, and is evolving rapidly.
Mozilla’s mission is to advance the Open Web. We believe that we can offer a positive experience if we provide support for the SWF format that is still used on many web sites, especially on mobile devices where the Adobe Flash Player is not available.
The Open Web can be further advanced by making rich media capabilities, previously only available in Flash, also available in the native web browser stack. Shumway is an exciting opportunity to do that for SWF, and we welcome support from external contributors as we advance the technology. We are reaching out to technical users who are interested in contributing to the Shumway implementation in these five areas:
1. Core. This module includes the main file format parser, the rasterizer, and event system.
2. AVM1. JavaScript interpreter for ActionScript version 1 and version 2 bytecode.
3. AVM2. JavaScript interpreter and JIT compiler for ActionScript version 3 bytecode.
4. Browser Integration handles the glue between the web browser and the Shumway runtime.
5. Testing/Demos. Add good demo and test files/links to Shumway.
