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 ffmpeg with VDA in action (and inspect mpv's output to make sure VDA is actually being used:

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.

ffmpeg with patch committed in r117917. ffmpeg-devel with patch and updated to latest git master committed in r117918.

Thanks for the patch.

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