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:

{{{ 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] AO: [coreaudio] 48000Hz stereo 2ch float AV: 00:00:00 / 00:41:17 (0%) A-V: 0.000 Cache: 99% VO: [opengl-hq] 1280x720 => 1280x720 vda <<< }}}

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. -- Ticket URL: <https://trac.macports.org/ticket/42863#comment:3> MacPorts <http://www.macports.org/> Ports system for OS X
