Gnash is a GNU Flash movie player. Previously, it was only possible to play flash movies with proprietary software. While there are some other free flash players, none support anything beyond SWF v4. Gnash is based on GameSWF, and supports many SWF v7 features.
The main developer's web site for Gnash is located on the Free Software Foundation's Savannah project support server. This site allows you to file bugs, or view the sources in CVS.
- Runs standalone
- Gnash can run standalone to play flash movies.
- Browser plugin
- Gnash can also run as a plugin from within most Mozilla derived browsers, such as Firefox. Gnash also has support for Konqueror.
- SWF v7+ compliant
- Gnash can play many current flash movies.
- Streaming Video
- Gnash supports the viewing of streaming video from popular video sharing sites like Lulu.tv or YouTube.com.
- XML Message server
- Gnash also supports an XML based message system as documented in the Flash Format specification.
- High Quality Output
- Gnash uses OpenGL for rendering the graphics on the desktop, and AntiGrain (AGG) for embedded framebuffer only devices.
- Free Software
- Gnash is 100% free software. For more information on the GPL, go to the Free Software Foundation web site.
- Better Security
- Gnash pays extra attention to all network connections, and allows the user to control access.
- Gnash supports extending ActionScript by creating your own. You can write wrappers for any development library, and import them into the player.
Gnash is being actively developed at the moment. Therefore, although many features work, not all movies play successfully. The first beta release of Gnash has just been made at version 0.8.2 on March 5, 2008.
Win32 users can now download an executable based on the 0.8.2 release.
CVS Access to Sources
The latest Gnash sources are also available via anonymous CVS. Use the following commands to check them out (just hit return when you are prompted for the password):
export CVS_RSH="ssh" cvs -z3 -d:pserver:email@example.com:/sources/gnash co gnash
If you cannot use ssh because you only have access to the Internet through a proxy, you can still get the latest version from a directory of daily cvs snapshots on the web.
The rough draft of the manual describing the most recent release (0.8.0) is available in a variety of formats.

Alternately, you may build the documentation from your checkout. Please refer to the instructions in the current manual for instructions on how to do this.
You can also view Doxygen produced documentation that is automatically generated by scanning the sources. This is aimed at developers, but can be useful to others as well.
