I forgot to mention, that the screenshot is a screenshot of YouTube and not of VLC.
VLC doesn't have an hyperscale cloud backend to generate and serve the frame cards, as YouTube does...
How cloud relates to this issue?
Because a cloud allows you to precalculate and store such cards (or even generate them on the fly but that's unlikely).
For VLC it would require either to precalculate those and waste user space drive or open a second stream just to decode it but it would require the ability to open 2 streams (which is not always possible due to unique tokens or resources) and decode it which is not always possible due to a lack of available hw decoders or take a huge amount of resources if it's a 4K HDR stream.
There are too many unknown constraints to be able to reliably propose this kind of feature.
