Re: [Interest] Android: do not deploy FFmpeg media plugin
Hi, We introduced more precise plugin deployment mechanism recently, so you can try adding something like: qt_import_plugins( EXCLUDE Qt6::QFFmpegMediaPlugin ) See https://doc.qt.io/qt-6/qt-import-plugins.html for details.

Re: [Interest] Errors while building Qt 6 on Windows
Hi Daljit*,* Please remove C:/Strawberry from path. before running configure. Or at least please make sure that it goes after the mingw provided by Qt. Thanks!

Re: [Interest] how to link my own DBus lib build to Qt 6.4?
Hi, You may try to override the system library using the LD_PRELOAD environment variable. So ld will prefer to resolve the missing symbols from your library but not the system one: https://man7.org/linux/man-pages/man8/ld.so.8.html Also IRRC, setting LD_LIBRARY_PATH to the directory containing the custom library, may force using your library instead of the system one.

Hi, Do you use Qt Creator to build, deploy and run the application? If yes I would guess you need to switch the "Run" target on in bottom part of the left panel.

Re: [Interest] License for Qt6 QtMultimedia module (LGPL?)
Shadertools module provides an executable that is used by multimedia at build time only. So there is no runtime dependencies between qtmultimedia and shadertools, so that's the key, I guess.
