I have inserted a player from a website that streams a channel using an iframe. While I have managed to make the iframe responsive, the video player inside the iframe does not adapt to changes in viewport size. Despite trying various solutions found online, none seem to make the content inside the iframe responsive.
Is there a method to make the video player inside the iframe responsive without access to the source code?
Please be aware that I do not have control over the source code of the player.
