Commit 4dfcdb8dd0 and 1fb0a77fc prevent me from viewing live TV. Reverting these 2 commits restores normality.

  • The FE & BE both run git master on one box
  • The BE is setup to use the demo recorder.

Summary: Revert commit 4dfcdb8dd0 - Fix SQL reconnection logic...backend

Lawrence, did you check your backend configuration?

From the error message it looks like you don't have an input configured for your recorder.

The setup was working perfectly before 'pull'ing these commits and worked again after reverting them. It's reproducible.

The BE doesn't have a real tuner, it's configured with a demo and a file recorder. My production system with real tuners is too valuable to use for testing.

You still need to configure the demo recorder properly. From the data you've produced it appears that a configuration error wasn't getting reported before that and it is now.
