I need recommendation on a reliable open source flash player software that can be used to play flash videos on a website. I have tried the osflv player but it does not seem to work.
Another example of an attempt to re-implement the Flash player is the Ruffle project, though it is still in early development.
However, it would be best to avoid using Flash technology on your website if possible. Alternative options include re-exporting the content as HTML5 or a video in Adobe Animate (if you still have the source file for the video) or making a high-quality screen recording of your video and embedding that on your website.
If you are simply attempting to view Flash content, remember that Flash can be re-enabled through your browser settings until mid-to-late 2020. In addition, there is a standalone desktop Flash Player projector that can also be used to play SWF files, provided you're willing to take a quick look at the source code of the webpage containing the Flash video/animation to locate the URL of the SWF file. Many Flash games are also being archived by the Flashpoint project.
you can use this project . I already used this project and there was no problem
