tv_find_grabbers should give you a list of available grabbers.

Sounds like you need to install xmltv.

OK I do understand your point of view. I thought since the patch is such an unobstructive simple 3 line patch that will prevent the abort it was worth a try to get this fixed not just for mythpreviewgen but for all Qt apps affected by this problem even the broken ones :oops: :roll:. Anyway thanks fo...

I admit it's a grey area :? The docs for QCoreApplication also say This class is used by non-GUI applications to provide their event loop. For non-GUI application that uses Qt, there should be exactly one QCoreApplication object. For GUI applications, see QGuiApplication. For applications that use t...

Hi tumic

I must have missed that can you please point me to the Qt documentation that says QImage requires a QGuiApplication. Thanks.

Yes the easy fix is to just remove the PBFImage plugin if you don't need it. We see this as a bug with the plugin not with MythTV. The plugin shouldn't be causing an abort it should be more friendly to other applications that use QCoreApplication and not assume all applications use QGuiApplication o...

You'll probably have to hack the code to get it to do what you want.

I know nothing about the uPnp code but this looks promising try changing the ORDER BY clause here and see what happens.

OK that's more like it :) It looks like you have installed an unofficial Qt image plugin for displaying Mapbox vector tiles. That's the PBFPlugin class that doesn't appear in the official Qt source code but does appear on github here :- https://github.com/tumic0/QtPBFImagePlugin It's not really a My...

Yes of cause in an ideal world MythTV would be able to keep trying to connect to the HDHOMERUN if it can't connect at start up but that currently isn't possible. Your best work around is to fix your setup to delay starting mythbackend until the network is fully up using the tools provided by whateve...

Thanks for testing again unfortunately the way you used gdb isn't telling us anything useful since it didn't abort. gdb is just waiting for you to tell it what to do next. If you repeat what you did to get the first abort that showed this Thread 1 "mythpreviewgen" received signal SIGABRT, Aborted. _...

Thanks for testing. Can you revert that change and try to get a better backtrace? We need to see what are the functions called before the crash that is causing QFontDatabase to be used since mythpreviewgen shouldn't be using any GUI stuff :roll: After the crash in gdb try typing thread apply all bt ...

Try changing the QCoreApplication here
https://github.com/MythTV/mythtv/blob/m ... n.cpp#L158
to QGuiApplication or QApplication

You may also have to do the same here

Are you using the MYTHCONFDIR method or are you using the default method of using the users home directory to store the config? Easy way to find out where a mythtv app is looking for the config is to look at the log. At the start you will see a line like :- 2020-04-24 11:54:46.876108 N [4930/4930] t...

A quick follow up on this. It turns out this was caused by some code clean up that didn't quite work as intended so has be reverted by David Hampton. https://github.com/MythTV/mythtv/commit/917a2087ef032b https://code.mythtv.org/trac/ticket/13613 I've tested master and it works now. Please update an...

Looks like something got broke I can also reproduce it in master :cry: Unfortunately non of the plugins have any maintainers any more so this is unlikely to get fixed. For anyone who want to try to fix it this is the BT (nothing stands out to me why it should crash there so it's going to require som...
