I see there were no definitive answers to your question. I ran into a similar problem on 1920x1080 vids, after upgrading my GPU drivers. Suddenly VLC 2 wouldn't play them. It would open them, display a frame, stall on that frame while seeker button advanced. If I clicked on another point on the seek bar, it would display that frame & so on.
MPC-HC played the vids OK. In my case, I realized it must be connected to me upgrading graphics drivers - but no idea which setting(s) was involved.
Stumbled on Video Settings > Output, & saw it was "Default." I don't know what it ever was before because never had to look. Remembered reading the Nvidia drivers use (I thought ???) Open GL. Just playing w/ settings, changed the selection in VLC video settings output to OpenGL & the 1920x1080 vids (several diff formats) started playing fine.
There may be OTHER output settings I could've chosen that would also work, but on my box, "Default" didn't work.
So, if you've upgraded graphics drivers (or maybe need to), VLC may / may not choose the right video output setting for high res vids.
