According to 
https://wiki.archlinux.org/index.php/Hardware_video_acceleration#Verification 
there are utilities to verify the absence/presence of each API.  I 
haven't checked to see if they're available for an EL7-flavoured system.

I'm noticing that Arch tends to have good, comprehensive, and not 
dangerously-out-of-date documentation... unlike certain other more 
popular distros.
