Comment (by ionic@…):

 Thanks for your effort. Updating `mpv` is a delicate matter, especially
 due to the many patches and because I want it to compile on both 10.6 and
 10.7 still. That means also updating and testing on my 10.6 VM, which
 takes a long time...

 Don't count on 0.15.0 during the next few days, especially since features
 have been dropped which I need to re-evaluate.
