Can't Run Nextpvr.exe Client After Upgrade

[gkw1973]

I suspect it's because you're using a using a generic Microsoft display driver for your machine, and it doesn't support OpenGL.

I can see see some comments online about Intel not providing a Win10 set of drivers for this Q45 chipset. Some people have indicated you can install the old Intel supplied Win7 driver. I'm not sure whether this will resolve the issue for you or not though.

I had previously stated that the previous version I had was 5.1.1 (210329), available March 29, 2021, and I had no problems with it.  Someone had previously mentioned that there were some files missing from the x86 installer.  Could this be causing my problem? Was OpenGL added to NextPVR after my previous installation?

5.2.0 was a big change. Previously the UI rendering was done with GDI graphics and Direct2D for display. That is all gone. It's now based on Skia graphics with OpenGL for display.

This was done because Microsoft has said they are no longer developing GDI, and it will not be supported in any future version of .NET. (including the .NET 6 we will be moving to in a next couple of months)

5.2 uses a new graphics engine designed for all future development in dotnet 6 later on.  Did you ever try Kodi with NextPVR.

Look, it is still totally possible it is just a missing runtime file or something (though I'm leaning towards it being a case of your graphics device not supporting OpenGL). If it is a missing file, it's very difficult for me to tell from here what it might be, and the problem is unique to you at this stage. There is a Microsoft tool for seeing missing runtime dependencies, called Fusion Log Viewer, but I it's kind of complicated, and I don't really know much about it, so I'm not well placed to give you exact instructions of what you need to do.

No, I did not try Kodi.  Here's what I've been doing in between all the various tests.  Using the web version, I installed my tuner, scanned for channels, set up my Schedules Direct account, set up my recording preferences and programs to record.  The recording is successful.  I've recorded two programs tonight.  The big problem, as I originally saw it, was a way to play the recorded videos.  Normally, I'd run the nextpvr.exe program to get the traditional interface, select 'Recordings' and watch.  Obviously, doing that caused all of the problems I'm having.  So, using the web version, I clicked on the 'Recordings' menu at the top of the screen, selected one of the series that recorded tonight, and three episodes appeared.  The first one listed had a 'Play' button associated with it.  I clicked on it and the episode started to play, but then stopped and an error was displayed by the control buttons (Play, Pause, Fast Forward, etc.) saying that the browser prevented playing of the video.  There's a picture in picture option, so I selected it and a second, smaller window appeared and the recorded episode started playing in it.  I exited out of the smaller window and the image was transferred to the main window and started playing.  I'm using the Firefox browser.  If that wouldn't work, I was going to use the VLC Media Player to play the recorded videos.  I guess that's the process I'm going to have to use from now on.

Try allowing autoplay in firefox, by clicking the icon shown here.

I have also added a "-nogl" command line option for the next build, which allows you to run without opengl. The UI animations aren't as smooth, but hopefully it'll give you a last resort if you can't get things going any other way.

Hooray!  That works great!

Thank you very much for that!
