If im not mistaken AMD has enhancement feature for video, though its not like SRS.
Also VSR is something different, as it renders a higher resolution image and scales down to monitor native. There should be no reconstruction as SRS does, which basicly enhanced edges to make them visible even if they are supposed to be less than half of the width of a pixel onscreen..
But the idea is good, video-FSR could be nice to have. But it also depends heavily one the spurce-stream.
You could try using vlc and some shader plugins, if you have the URL for the media in browser, and play with the video-options in the adrenalin panel
