      It wasn't as fast as I thought, I thought it would be easier to just port the code from Clementine, but turns out there are two issues, QGLWidget being deprecated, and projectm API completely changed to a plain C API in version 4.
      All projectm visualizations works fine when I use Qt 5 with QGLWidget. But once I switch to QOpenGLWidget, only some visualizations work correctly, same issue with both Qt 5 and 6.

      And for ProjectM, everything works fine with version 3, I've added support for version 4 to by using ifdef's in the code, but nothing works yet, I'm missing some things, like what replaces projectM_resetGL in ProjectMVisualisation::SceneRectChanged, I don't see anything.

      The songs I'm testing with are already 44100Hz/16bit. Also the buffer is converted to 16 bit anyway in GstEnginePipeline::BufferProbeCallback, so I don't think that's an issue.

      Anyway, it took a lot longer to do this than anticipated, so if you or someone else wants to look into it, it would be appreciated. The main issue now is getting it to work with, QOpenGLWidget, if that's fixed then we can merge the code without the projectm 4 support.

        Might be worth to mention, no Linux distros seem to have projectm version 4 yet, so it's not a major issue if we continue to use version 3 for a while longer.

          @jonas I started to fiddle with this last week, got into some issues.... first of all It looks like I need Qt 5.6 to compile it, have to get it so I can test the Qt 5 part, as Ubuntu still has 5.3 even on 24.04 LTS

          Using libprojectM 4 and Qt6, it segfaults exactly when it is supposed to start rendering to the opengl context. It looks like if it initializes it, but when AddBufferConsumer gets triggered, when data is supposed to arrive and draw to the screen, it segfaults. I still have no clue but I'm trying to understand; I saw something about this:

          QOpenGLWidget::makeCurrent(): This function makes the context associated with a QOpenGLWidget the current context for rendering. This is analogous to "setting" the context.

          and also doneCurrent(), I believe this is missing but i'm not sure how to implement due to the inheritance of the visualizercontainer class

            Qt 5.6 is ancient, do you mean Qt 6.5?

            I tested with Qt 5.15.14 and the latest Qt 6 (dev) code.

            Turns out that the issue I'm seeing with QOpenGLWidget is known to projectm:

              @jonas its strange indeed, I believe to already have compiled strawberry against qt 5 before.... but maybe not. Inspecting, I see I kinda have qt 5.15 here 😛

              ~/strawberry$ qmake -v
QMake version 3.1
Using Qt version 5.15.13 in /usr/lib/x86_64-linux-gnu

              qtbase5-dev/noble,now 5.15.13+dfsg-1ubuntu1 amd64 [installed]
  Qt 5 base development files

              So indeed, I'm crazy, I was sick as hell when I tought to have Qt 5.3, I saw the wrong version and that sticked to my head, I double checked and of course, its not Qt 5.1 or 5.3 its 5. 15 !!!! Just shoot me.

              The error I receive with -DBUILD_WITH_QT6=off is this:

              strawberry/src/globalshortcuts/globalshortcut-x11.cpp:56:7: error: ‘QNativeInterface’ has not been declared
   56 |   if (QNativeInterface::QX11Application *x11_app = qApp->nativeInterface<QNativeInterface::QX11Application>()) {
      |       ^~~~~~~~~~~~~~~~

              QNativeInterface, Which first appeared in Qt 5.6, thats the huge mess I made, sorry.
              The error has nothing to do with Qt versions anyway. Maybe some typo in ifdefs? or missing headers? This is from a fresh master clone.

              About the issue in QOpenGLWidget,
              since we are spawning a new window, we could use SDL2 instead just for that.. could we?

              Strange that for you and other ppl the rendering becomes garbage, for me it plain segfaults as soon as it tries to render ( libprojectM 4, Qt 6 )

              I have onboard INTEL graphics

                    I've tested without QGraphicsScene and I'm having the same issue.
                    Making ProjectMVisualization inherit public QOpenGLWidget, protected QOpenGLFunctions, public GstBufferConsumer

                    Then i override paintGL like this:

                    void ProjectMVisualization::paintGL() {

  QPainter p(this);

  p.beginNativePainting();

#ifdef HAVE_PROJECTM4
  if (projectm_instance_) {
    projectm_set_window_size(projectm_instance_, width() * pixel_ratio_, height() * pixel_ratio_);
    projectm_opengl_render_frame(projectm_instance_);
  }
#else
  projectm_->projectM_resetGL(width() * pixel_ratio_, height() * pixel_ratio_);
  projectm_->renderFrame();
#endif

  p.endNativePainting();

  update();

}

                      Here is how it some look, just so we are talking about the same thing:

                      ba6c1e03-ab3d-41b9-aaa8-931bde328641-image.png

                      This is with ProjectM3, with version 4 I still have no luck.

                        @Gustavo-L-Conte said in Reintegrate projectM Visualizer:

                        QX11Application

                        Did you clean the build directory, or at least delete CMakeCache.txt before you built with Qt 5, QX11Application is part of Qt 6.2 and newer, it shouldn't be included anywhere with Qt 5.
                        Variables in CMake are cached, so it does not help to re-run cmake without deleting the cache first.
                        Also, you should use: -DBUILD_WITH_QT5=ON to disable autodetecting Qt version, setting BUILD_WITH_QT6 to OFF won't do that.

                          @jonas yep I tried the same trhink you did, the override in paintGL, but with projectM4 and Qt6, for me only blank screen 😞

                          and yes, I realized about the flags too. From certain point I was always doing a make clean, and I was able to successfully build with Qt5,
                          with -DHAVE_X11_GLOBALSHORTCUTS=off

                          (i think it was that flag) because it issued that error I pointed above; but thats not necessary now I see, if I remove the build dir. 😛 feeling pretty dumb.

                          anyway, both ways for me, projectM4 or below, gives me only blank screen. I'm rebuilding right now with all combinations to test everything again 😛

                            @jonas thanks!!!!! now visualization at least shows for me with Qt5 and projectM 3, as expected!

                            Gonna try things I did before but now properly cleaning the builddir LoL

                              about the v4, I think its some config missing. I'm going to double check after taking a break, all of these: (got from frontend-SDL2)

                                If I add a call to projectm_playlist_play_next or projectm_playlist_set_position, it crashes on projectm_opengl_render_frame.

                                  Which makes me think it wasn't trying to render any visualization, because it wasn't set before.

                                        This is the crash I'm seeing with the latest ProjectM code from git.:

                                          I just saw the visualisations2 branch, gonna take a look!!! 😄

                                          @jonas for libprojectM v4, in ConsumeBuffer, I removed the static cast to short on samples_per_channel and stops segfaulting...

                                          #ifdef HAVE_PROJECTM4
  if (projectm_instance_) {
    const unsigned int samples_per_channel = (map.size) / sizeof(short) / 2;
    const short *data = reinterpret_cast<short*>(map.data);
    projectm_pcm_add_int16(projectm_instance_, data, samples_per_channel, PROJECTM_STEREO);
  }

                                            nice nice this visualization2 branch.... its cool to see we had the same ideas and its even better to see then implemented the right way LoL

                                            Okey, compiled, and after removing static_cast<short> on (map.size) I could play a song without crashing... black screen and no overlay, but the selector menu works.
                                            One of the things I did to test yesterday was to succesfully render an animated triangle inside the drawBackground, proving that OpenGL context is working.
                                            I really think Its something with the preset loading like you said, I really think so. Yesterday, after debugging a LOT, including sending random data in ConsumeBuffer, with not a single pixel plot by render_frame, everything indicates that there is a gap between the PCM send and the render_frame; I believe your hypothesis of no preset loaded is the right track here. Even more true since the logo M does not even load.
