I've just come back to this with the new ffmpeg4 master and my build 
system upgraded to f27 - which overwrote the mythchain patch #65

After mending that I now have two SRPMS (mythtv and plugins, maybe 
identical) and a new problem:

Start: buildsrpm
Start: rpmbuild -bs

Thanks, of course, for the instructions - and the scripts.  I'm happy 
running my current build at present, but a fix for this new buildsystem 
would be great.
