[solved] Direct3D device could not be created - prohibiting mp start (1 Viewer)

[Owlsroost]

When the error occurs MP is making a Windows Direct3D system call (CreateDeviceEx), and that is returning 'not successful' - hence the error message.

Did you have any .NET updates around the time the problem started?

If you start MP in windowed mode (not full screen) does it work or fail?

Yes.

Fails.

Assuming you are running MP 1.18, can you both try the attached 'MediaPortal.exe' please, which provides more logging information?

You must have the log level set to 'debug' in MP Configuration.

Just copy the 'MediaPortal.exe' from the attached zip file into 'C:\Program Files (x86)\Team MediaPortal\MediaPortal' (after making a backup copy of the original file), run MP and upload the logs please.

OK - I can reproduce the problem, but I haven't found the root cause of the problem yet.

It looks like the MediaPortal.xml settings file (in C:\ProgramData\Team MediaPortal\MediaPortal) can get invalid values for these lines e.g.:

<entry name="backupsizewidth">120</entry>
<entry name="backupsizeheight">0</entry>

...which then causes the crash - but only if MP is starting in 'windowed' mode (not fullscreen).

Please try this which hopefully should fix it for now:

Open the MP configuration utility, go to General -> Startup/Resume Settings, then tick 'Start MediaPortal in fullscreen mode'.

Close MP configuration, then start MP client - hopefully it will start OK. Close MP (which should save valid values for those lines mentioned above).

If you need to run MP in windowed mode afterwards, open MP config and un-tick 'Start MediaPortal in fullscreen mode'.

I'll try and fix the code so that those values in MediaPortal.xml are sanity checked and don't cause an error....

Please try the attached replacement 'MediaPortal.exe' - this should correct/workaround the 'invalid values' problem.

To install, copy 'MediaPortal.exe' from the zip file into C:\Program Files (x86)\Team MediaPortal\MediaPortal (after making a backup copy of the original file)

Thank you, it's working!
Unfortunately, since I got it working with your first solution, I can't really test the patched exe since I would not see any difference, right?

Correct, it should not fix/change anything if it's already working OK, but it should also stop the problem happening again.

Thanks @Owlsroost for investigate this it's a regression introduce by my change so it seems and really happy that you take the time to resolve this

I have since today also this issue that mp doesn't start
neither in fullscreen nor in windowed mode.

It hangs while saying "initializing directx"

Logfiles are attached

Thanks for any support
