Thank you to everyone who replied!

In the end I took a risk and did the 30 to 31 upgrade while excluding 
the mythffmpeg-31* package.  Fedora upgraded without issue and MythTV 
works afterwards, perhaps because there was another valid package to 
supply the missing library?

Immediately after upgrading there were these packages available:

     Upgrade python3-future-0.18.2-2.fc31.noarch @updates
     Upgrade mytharchive-31.0-1.fc31.x86_64 @rpmfusion-free-updates
     Upgrade mythffmpeg-31.0-1.fc31.x86_64 @rpmfusion-free-updates
     Upgrade mythtv-backend-31.0-1.fc31.x86_64 @rpmfusion-free-updates
     Upgrade mythtv-base-themes-31.0-1.fc31.x86_64 @rpmfusion-free-updates
     Upgrade mythtv-common-31.0-1.fc31.x86_64 @rpmfusion-free-updates
     Upgrade mythtv-frontend-31.0-1.fc31.x86_64 @rpmfusion-free-updates
     Upgrade mythtv-libs-31.0-1.fc31.x86_64 @rpmfusion-free-updates
     Upgrade mythtv-setup-31.0-1.fc31.x86_64 @rpmfusion-free-updates
     Upgrade python3-MythTV-31.0-1.fc31.noarch @rpmfusion-free-updates

which I installed.  I imagine these extra packages weren't installed in 
the upgrade due to my use of the exclusion option.


Everything seems to have worked and I didn't need to use the test 
versions of packages which were produced (thanks for that!).

My lesson from this is: Upgrade to the supported version of Fedora no 
later than when two releases are available.  Fedora technically supports 
3 versions at once (I think for around month after every new release) 
but don't leave it that long!


Thanks again!
