Comment (by jpilk):

 Unfortunately that commit broke playback of DVB radio, where I normally
 see a blank screen.  I haven't tried it with the 'interactive' OSD or
 other visuals.

 The audio playback is chopped into brief chunks between longer gaps.  el7
 with old intel hardware gives this, while my f28 vdpau-box currently
 reports an even larger 'audio ahead' value of almost a day.

 I may be able to build with patches now, although I haven't done it yet.
