If you're feeling advanturous, fetch ​http://mpv.io/ and configure + build + install it with waf, then run mpv -vo opengl-hq -hwdec vda yourfavoriteH264video.mkv to see VDA in action (and inspect mpv's output to make sure VDA is actually being used: 

Trying to use hardware decoding.
Selected video codec: H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 [lavc:h264]
Selected audio codec: ATSC A/52A (AC-3) [lavc:ac3]

Since you've done this already, it would great if you'd put together a Portfile for mpv and submit it on a separate ticket. I'd be glad to commit it for you. The waf PortGroup makes it pretty simple.

Please have a look at #40844, I added a new mpv Portfile (and minimal patches) there. Sorry it took me so long.
