Re: Myth31 /Ubuntu20.04 - mysqld CPU usage every 1 min (MythFillDB)

Try turning off the 'Run listings data program at time suggested' setting.

You will find it in mythtv-setup under 1. General -> Programme Schedule Downloading Options -> Automatically update programme listings

Re: Upgrading fromV30 to V31

I suspect the libcec thing is a red herring. Having stale libraries and filters have been known to cause a segfault on startup. If it's not that then you will have run mythfrontend under gdb and get a backtrace for us to help identify what the problem is. There are Ubuntu specific instructions here ...

Re: Upgrading fromV30 to V31

I think you may be missing libcec4 . I only see the deb packaging has libcec-dev as a build dependency and not libcec4 as runtime dependency so you may be on to something. Wonder why no one has had this problem before? Let me know if installing libcec4 fixes the problem for you and I will add it to ...

tv_find_grabbers should give you a list of available grabbers.

Re: [Solved] Mythpreviewgen Not Happy

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...

Re: [Solved] Mythpreviewgen Not Happy

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...

Re: [Solved] Mythpreviewgen Not Happy

Hi tumic

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

Re: [Solved] Mythpreviewgen Not Happy

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...

Re: Inverting program list order for UPnP

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.

Re: Mythpreviewgen Not Happy

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...

Re: Mythtv fails to start because network isn't up.

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...

Re: Mythpreviewgen Not Happy

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. _...

Re: Mythpreviewgen Not Happy

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 ...

Re: Mythpreviewgen Not Happy

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
