Build started.  Thanks!

I downgraded the el7 box before recalling that AVSync2 is a 'setting' 
that can be disabled.

The build in my earlier post played normally on exit from Edit or Pause, 
although still reporting huge sync errors.

------------------

Built and running in f28.  No problems seen :-)

There doesn't seem any need to look for 'settings' to change the 
readings below, and I haven't - but radio seems harder work than video :-)

On screen playback data shows Codec/Dec ffmpeg, CPUs around 2 * 10%

For TV 704x576 at 25.00fps, Codec/Dec  MPEG-2 vdpau, CPUs variable but 
often around 2 * 6%
