Idea, add a floating top right, info button when hovering the player ? A bit like Vimeo has for Like, Watch Later, Collection, Share ?

Possibly could also be implemented as an endcard (like we have in TMH), but we have had tickets about how the link to the video details page should be more prominent, so....

This won't work for audio files however. Just add a toolbar button for audio files ? Might become crowded... Audio player keeps giving me nightmares on this front...
