[mythtv-users] 2Backends

Fri Dec 9 11:07:27 UTC 2016

After a lot of fiddling I have a working system (on a new blank db, but not with a backup). Before troubling the dev folk can anybody help with this:

My 0.27 is modestly recent
mythbackend version: fixes/0.27 [v0.27-193-g8ee257c] www.mythtv.org

but when I try to run an upgrade on that DB

[poohcorner] /home/jam [142]% mythbackend

This version of MythTV requires an updated database. (schema is 27 versions behind)

Please run mythtv-setup or mythbackend to update your database.

Stephen with mythbuntu 14.04 I have had good experience over the years.
I installed 16.04.1 on 4 machines. I fiddled the first install, but the rest were clean.
The first 3 did *not* work the last did. Using hindsight I went back and made machine 1 work.

Machine 1: 2012 mac mini - i5 core duo, 4G RAM, 500G disk
Machine 2: amd64 4G/500G dual core (old so I forget detail)
Machine 3: nuc i5 4G/128G (duo)
Machine 4: nuc i3 4G/256G (duo)

To get machine1 to run I enable mythbackend.service with systemctl
I removed the .config/autostart/setup.desktop link

All somewhat daunting to the neophite, doubly daunting to see ‘Can’t connect to master backend’ overlaid over the movie you’re watching!!

My last hurdle (wireshark tomorrow) on 0.27 I play a video over uPnP on my samsung tv. On 0.28 the same video has the samsung complaining ‘unsupported file format’. It must be a naming thing.

I’d like to believe I was being harsh, but the issues I’ve had have been pretty harsh.
I assume that the hardware has an effect on the install (actually I’m certaiin it does)
