When Flash Player was still being supported, using LaTeX Beamer for presentations, one was able to compile a PDF with embedded videos/gifs in it (using \includemedia[]). The videos were interactive at least with the simple buttons such as play/pause/repeat. Now Flash Player is no longer supported, and even though the PDF is the same, and you can even continue to compile such PDFs, I can find no way of playing the videos. In Adobe Reader or Adobe Acrobat, if one tries to click on the embedded video to play it, one gets the following message:
This content requires Flash Player, which is no longer supported.
Adobe Acrobat gives you a "Learn More" clickable option which then links you to their webpage: https://helpx.adobe.com/acrobat/using/flash-player-needed-acrobat-reader.html?mv=product&mv2=acrobat. But even that does not seem help; there are alternatives there for Flash Player all right, but I do not see how any of them enables you to play embedded videos on a PDF. What is the actual alternative for opening such PDFs and being able to play the embedded videos therein?
(Note: If I may, to this end, I propose of adding a new tag, involving the words "flash player alternative", in some manner.)
