VDPAU Not Functional At 4K

Unfortunately, that doesn’t help me since the guy who runs VLC and makes all the development decisions won’t allow CUVID to be added to the player’s capabilities and apparently nobody else has implemented it either, so my only choice is to use VDPAU or switch to Windows. To make matters worse, the versions of FFMPEG used in Ubuntu are the older 2.X release tree and not the newer ones with newer functions like CUVID, so I’m basically screwed.
