According to https://wiki.archlinux.org/index.php/Hardware_video_acceleration#Verificatio... 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I'm noticing that Arch tends to have good, comprehensive, and not dangerously-out-of-date documentation...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.

If you can install mplayer easily, this should tell you (me!):
mplayer -vo help |grep vdpau
but maybe also test:
mplayer -vo vdpau foobar.mp4
and look for a line like: VO: [vdpau] 640x480 => 640x480 Planar YV12
If you don't have vdpau support, the VO will be something else, or nothing will play at all.
Well, I *could* install mplayer, but not easily. I did install it on another EL7 clone system, but it required installing nux-dextop-release and getting mplayer and all the MPEG support libraries from the nux repos. There were a few conflicts I had to manage after that, and eventually ended up disabling that repo by default so automatic updates would work again. It's a little too much complexity to answer a question I'm not all that invested in personally. So, unless I need mplayer and/or MPEG support on this particular system for any other reason, I'm inclined to leave well enough alone for now.
