  Hello,

  We are doing a migration to qt5.15 and during the process we have seen that the qt recipies for qtmultimedia includes gstreamer.

  We want to use audiocapture instead of videonode and we have forced through a patch in /src/plugins/plugins.pro.

  My question is if this can have any negative effect or if there is a cleaner way to do this.

  Thanks

  @nben386 Still not able to get gstreamer working with QML.
  I'm considering using another approach and creating my own video sink class.
  If your Qt version is 6, there is a QVideoSink class that could help us, but I don't have enough time and it'll take some time to implement it and check if it works

  @Huqis Do you have more than one Qt installation? If so use absolute path to windeployqt.exe.
  Do you execute windeployqt.exe inside preconfigured Qt terminal (cmd)?

  @jsulm yeah, i should have worded it differently. compilers are same as you would get without Qt creator but there is a pre-step before actual code gets compiled by Qt creator itself i.e. moc ?. i will redact my statement. thanks for the insight

  Hi,

  You should rather take a look at QWindow.

  That said, Qt already provides integration for many of the modern graphics API such as Direct3D or Vulkan. You might want to explore the scene graph documentation and the corresponding classes. Engines such as Ogre3D have integration that might of interest.

  @RayKn said in Translating between NL and EN:

  What do I do at initialization? Do I install the dutch translator even though the program is already set at dutch (also in QT Creator Designer the language is set to dutch).
  I really feel like I am missing something.

  The Qt translation system at runtime doesn't know anything about specific langauges. It just checks the installed QTranslators one by one whether they provide a translation for the source string / context combo, falling back to the original source string if nothing is found.

  If you don't need a nl translation because all the source strings are already in correct language , then you can as well remove the .nl file. Then all you have to do to switch from English to Dutch is to remove the translation file by calling QCoreApplication::removeTranslator() with the QTranslator object as argument.

  Sometimes it's useful though to keep a (partial) translation, for instance to be able to fix typos, or to handle plural forms correctly. In this case, you might want to have a partial .ts file for NL (-pluralsonly argument).

  That said, if it's true that the nl file is contains a correct translation, then your setup should actually work (even if slightly inorthodox). I suggest at least checking the return value of your installTranslator calls...

  Hey there,
  there was some discussion time ago that more templates could be added to Qt Creator. The development team is interested to know which templates do you think might be a good idea to include.

  This is the bug report issue: https://bugreports.qt.io/browse/PYSIDE-2372 in case you want to comment, or you could do it here.

  The following image display the current options.

  For example, I recently pushed a new one to see if it would make sense one project that uses QML_ELEMENT to expose a Python class to QML. https://codereview.qt-project.org/c/qt-creator/qt-creator/+/498769

  Any thoughts?

  Do not manually compress these files; you can leave it to Nginx to handle automatically. After adding these configurations to my Nginx conf file, automatic compression is enabled:

  gzip on; gzip_min_length 32k; gzip_buffers 4 16k; gzip_http_version 1.1; gzip_comp_level 2; gzip_types text/plain text/css text/xml application/xml application/json text/javascript application/javascript application/octet-stream;

  You can visit this address to see the compression effect. Open the F12 console in Chrome, and you will notice that the wasm file has been compressed.

  Hello everyone,
  (Apologies to forum admin, I confess also posted the same thread in topic [QT for Python], just thought to give it a try under this topic too)
  I am an indie developer working on a desktop app using Pyside6. Currently, my app is currently available for free to all users. However, I am now considering implementing embedded advertisements to monetize the app. I recently came across the QT Digital Advertising Platform, which seems to be an easy-to-use solution.

  I have been searching for documentation on how to integrate the QT Digital Advertising Platform with Pyside6, but I haven't been able to find much information specifically about its implementation with Pyside6.

  I have a couple of questions and would greatly appreciate it if anyone with knowledge in this area could help me out:

  Can Pyside6 be used with the QT Digital Advertising Platform?
  If the answer to the first question is yes, could you please point me towards any documentation or resources that provide information on implementing the QT Digital Advertising Platform specifically with Pyside6?
  Thank you in advance for any assistance you can provide!

  Qt Insight 1.1 has been released. The major new feature is report comparison, which allows users easily conduct A/B tests. Please read further details in the blog post.

  We are planning to publish new releases regularly from now on. Selected features in the releases are heavily based on user interviews and feedback. In the next release scheduled for mid-May, we are going to bring funnel support for Qt Insight.
