I managed to fix the crash by moving the Init function to the constructor. But the animations still doesn't look right.

Gustavo L Conte

@jonas way to go!!!!! That was fast. I got sick in bed these days just saw that right now.

Have you tried forcing 44100 Hz sample rate?

Here my projectMSDL only runs like this:

Recording audio from device "Default capturing device" (ID -1).
Opened audio recording device "System default capturing device" (ID -1) with 2 channels at 44100 Hz.

jonas

@Gustavo-L-Conte
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.

jonas

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.

Gustavo L Conte

@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

jonas

@Gustavo-L-Conte

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:

https://github.com/orgs/projectM-visualizer/discussions/820#discussioncomment-9864556

Gustavo L Conte

@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

@jonas look at this, this problem is not new at all!!!

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:

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

jonas

@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.

Gustavo L Conte

@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

Gustavo L Conte

@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)

projectm_set_preset_duration(projectMWrapper.ProjectM(), _displayDuration);
            projectm_set_preset_locked(projectMWrapper.ProjectM(), !projectm_get_preset_locked(projectMWrapper.ProjectM()));
                projectm_set_beat_sensitivity(_projectMWrapper.ProjectM(), beatSensitivity);
        projectm_set_window_size(_projectMHandle, renderWidth, renderHeight);
            projectm_set_aspect_correction(_projectMHandle, aspectCorrectionEnabled);
        projectm_set_window_size(_projectM, canvasWidth, canvasHeight);
        projectm_set_fps(_projectM, fps);
        projectm_set_mesh_size(_projectM, _projectMConfigView->getInt("meshX", 48), _projectMConfigView->getInt("meshY", 32));
        projectm_set_aspect_correction(_projectM, _projectMConfigView->getBool("aspectCorrectionEnabled", true));
        projectm_set_preset_locked(_projectM, _projectMConfigView->getBool("presetLocked", false));
        projectm_set_preset_duration(_projectM, _projectMConfigView->getDouble("displayDuration", 30.0));
        projectm_set_soft_cut_duration(_projectM, _projectMConfigView->getDouble("transitionDuration", 3.0));

@Gustavo-L-Conte

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.

@jonas exactly!!! makes total sense!

Im testing now Qt6 with lib v3, all presets are pretty good, did not see any bug at all!!!!!
