Lightspark supports most of ActionScript 3.0 and has an NPAPI plug-in.[2] It will fall back on Gnash, a free SWF player on ActionScript 1.0 and 2.0 (AVM1) code.
Lightspark supports OpenGL-based rendering and LLVM-based ActionScript execution and uses OpenGL shaders (GLSL). The player is compatible with H.264 Flash videos on YouTube.
The Lightspark player is completely portable.[3] It has been successfully built on Ubuntu 11.04 (Natty Narwhal) on PowerPC, x86, ARM and AMD64 architectures.[4] Lightspark has a Win32 branch for Microsoft Visual Studio[5] and introduced a Mozilla-compatible plug-in for Windows in version 0.5.3. Since then, the project hasn't seen any official Windows release, but newer versions are continuously built and made available through Jenkins.[6]
