youtube time machine just uses an embedded YT player. player.innerHTML = `<iframe src=" https://www.youtube.com/embed/${vid.id}?autoplay=1&rel=0&modestbranding=1"; allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>`; I replace ${vid.id}
however I've not tried controlling this video player using javascript... Here is another app that actually uses the iframe api ...... and it works fine in Windows 11 .... built with Livecode 10. I just tested it. https://browserapps.io/VideoAid/ Sorry I can't dig in, I don't have time, but maybe AI can help spot the difference.
