el7, kde, libvpx and gstreamer-plugins-good

[John Pilkington]

I have up-to-date F27 and SL7x (el7 clone) KDE boxes running 
mythtv-master installed from rpms built locally with this script - or, 
for el7, a slightly modified earlier version of it that disabled libvpx.

https://github.com/garybuhrmaster/packaging/blob/master/MythTV/rpm/README

mythtv-master requires a version of libvpx later than the one in the 
standard el7 repos, and the script now uses a COPR build that provides 
libvpx.so.5()(64bit).

gstreamer-plugins-good requires libvpx.so.1()(64bit)

mythtv does not require the gstreamer plugin, but it looks as if 
removing it would take most of KDE too. This surprises me. Is there an 
alternative?

TIA
