Video.js Flash Fallback SWF

videojs-swf is a legacy package that provides a compiled Flash (SWF) video player, designed to serve as a fallback technology for Video.js versions 5.x and below. In its era, it enabled Video.js to maintain a unified API, allowing its skins, plugins, and other features to function across both HTML5 and Flash environments, crucial for broader browser compatibility before HTML5 video was universally robust. The package, currently at version 5.4.2 (last updated in 2018), is essentially a build tool for a `.swf` asset rather than a directly importable JavaScript module. It has not seen active development in many years, aligning with the general end-of-life for Adobe Flash Player itself. For Video.js 6.x and above, the Flash tech was moved to a separate `videojs-flash` repository, though both `videojs-swf` and `videojs-flash` are now largely obsolete due to browser Flash EOL.
