Unable to launch backend service

[abhishikthaharsha]

Hi There,

I have followed the mythtv wiki page for installing the mythtv from source and setup the DB and configured the mythtv-setup with Demo Source as I do not have tuner. When I am launching the backend service it is not running and getting the error as in the log below. Attaching the DB dump if needed. Please help me in proceeding further.

I suggest you add a demo or import capture card, then add a demo video source. In the demo source specify "no grabber". Then add an input connection to connect the source to the tuner. Also add a channel to the source. Give the channel any number and any name. After this you should be able to start the backend.
