@Kevin470 The qt_standard_project_setup function doesn't set CMAKE_AUTORCC flag, only UIC and MOC. So you need to add: set(CMAKE_AUTORCC ON) before calling qt_add_executable.

@Mark81 I tried to check the signal enableMonitoringFinished and I get a success: void MyOpcUa::enableMonitoringFinished(QOpcUa::NodeAttribute attr, QOpcUa::UaStatusCode statusCode) { qDebug() << attr << statusCode; } QOpcUa::NodeAttribute::Value QOpcUa::Good

@Megamouse for such big files I recommend using the stream part of QTextStream and read file in chunks :D It really gives amazing performance improvement, regardless of which Qt version you are using. It will lower both CPU and RAM usage by a lot. Talking from experience here :-) Regarding the slowness issue: this sounds like something Qt devs should look into. Please consider reporting it on Qt bugtracker!

Hi @ChrisW67 , Thanks for your reply. This happens in my development machine. Plugins like "assimpsceneimport.dll, gltfsceneexport.dll, gltfsceneimport.dll" are available in my QT installation. Also, my filepath exists. gfem.GLB file is valid and I could load the file in the viewer you have recommended. I am using Qt open source version. Is Qt 3D available only for commercial version ? Thanks, Sridharan

@Aliviya Interesting... and what has Qt to do with it?

Seeing the PostgreSQL version you have (9.6), I am fairly certain that your issue is that you have an Intel only build or a ppc64/x86_64 at best.

@hskoglund I created the new topic.

@LT-K101 Have You Found Solution in This issue ?

@SGaist thanks for the reply... Although ffmpeg does support RTP, I Don't see if it's available on all supported platforms or only on some. As an alternative, I found this library https://github.com/ultravideo/uvgRTP I'll see if I can make something of it and integrate it with QtMultimedia, apparently if I get a stream of H264 (AVC) or H265 it will wrap it into (S)RTP, although only works on Windows, Mac and Linux, it would be cool if I get it to work also on iOS and Android (the platforms covered by my Qt subscription). Maybe I'll keep this open, if I manage to get it working it could help someone else.

@JonB well there are reasons, I want to set the default style based on wether the user has dark mode on or not, but I need to set it with QGuiApplication::setStyle(QStyle *style) before it is created to not break/disable CLI arguments (e.g. -style fusion) and environment variables.

@ioki9 said in Can't use built in SQLite functions after building SQLite plugin in Qt 6.5.1: I thought that linking to Qt SQLite was enough after rebuilding plugin and using header. It can't - it does not export the sqlite functions in any way (why should it).

@Christian-Ehrlicher That's probably what I was looking for, thanks. I was looking at the "signals and values pages" before, which of course had nothing.

What does '4k' mean? 4000x2000 pixel? If so you need at least 400020004bytes = 32MB of free, contiguous memory. As @JonB already said - please show use your loading and displaying code. Also it's not a good idea to load an image every 0.1 second.

@kluszon yes, it's explained in the Creating Shared Libraries.

@Christian-Ehrlicher My bad. Thank you, it worked! I need to up my cmake game...
