https://github.com/kencu/macports-ports/commit/1fb5ca6f44bd3d7bc7f359debde0391903477a53 I should have a PR in the next day or so. Works on 10.7 -- now I just have to build mpv on 10.6, 10.8, 10.9, and 10.10, and see what happens :> I think there's one more tweak needed in the videotoolbox section of the Portfile... Ken
