Reintegrate projectM Visualizer

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...
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. -
@Gustavo-L-Conte
The crash I'm getting isn't related toprojectm_pcm_add_int16
, it's happens when callingprojectm_opengl_render_frame
, I suspect it's NVIDIA related. Problem is that all my computers have nvidia graphics. -
I suspect the reason why QGraphicsView and QGraphicsScene was used is because of some additional things like the play buttons overlay, using a QMainWindow with a QOpenGLWidget directly didn't change much for me, other than the play buttons no longer working. It was just an attempt to see if it would solve any issue.
-
ProjectMPresetModel should probably use projectm directly to present the presets, not hold it's own data. I'll work on that.
-
@jonas lol sry for bothering about that again, but:
Instead of removing the typecast I'm now casting to unsigned short, it works too
const unsigned int samples_per_channel = static_cast<unsigned short>(map.size) / sizeof(int16_t) / 2;
Thats the only segfault I get. yep, Maybe yours is NVIDIA related, because I have INTEL onboard graphics
Is there a way for you to activate software rendering and bypass the GPU, just to test?export QT_QUICK_BACKEND=software export LIBGL_ALWAYS_SOFTWARE=1

@jonas When i do this:
int current_preset_ = projectm_playlist_get_position(projectm_playlist_instance_); qLog(Debug) << "Rendering frame for preset: " << current_preset_; projectm_set_window_size(projectm_instance_, static_cast<size_t>(width * pixel_ratio_), static_cast<size_t>(height * pixel_ratio_)); projectm_opengl_render_frame(projectm_instance_);
and then set lets say, 5 seconds interval, selecting all presets
it DOES increment the index printed

export QT_QUICK_BACKEND=software export LIBGL_ALWAYS_SOFTWARE=1
Setting these variables didn't do anything, but I've managed to make it crash less often by reinstalling the nvidia driver.
If you pull the latest changes from the visualisations branch I've fixed loading saved presets, the IndexOfPreset function was also broken with projectM 4.

just finishing building
these are MEsa variables:

@jonas I did not notice any difference running the app... except now it honours the selected presets. ( I think it "forgets" in previous versions, never understood what was going on)
Still no output, but here's a thing I saw:

This is my config file, is it supposed to be missing double quotes in the filenames?

QOpenGLFunctions::glGetError() returns GL_INVALID_ENUM (0x0501)
-
@jonas I saw this error code too before, at the time I tought we had to make OpenGL ES context but I never tried that
-
With ProjectM3 I do not get that error code, but on some presets I get
GL_INVALID_OPERATION
. -
@jonas
ProjectMGUI::initialize
(SDL2 frontend)_projectMWrapper = &projectMWrapper; _renderingWindow = renderingWindow.GetRenderingWindow(); _glContext = renderingWindow.GetGlContext(); ImGui_ImplSDL2_InitForOpenGL(_renderingWindow, _glContext); ImGui_ImplOpenGL3_Init("#version 130"); UpdateFontSize();
by settiing this version part could do the trick maybe?
-
But that code is using ImGui?
I actually got some presets from the original pack (https://github.com/projectM-visualizer/presets-projectm-classic) to work with ProjectM version 4 now using Qt 5 and QGLWidget. The ones starting with "Martin", but a few others too. No crashes either.
With Qt 6 and QOpenGLWidget, none of them work, and I also see crashes. -
@jonas I did the version stuff in the initializeGL, tested with qLog if it was setting the version, it did, and it didnt change anything.....
I'm thinking now, maybe these crashes could be some sort of related to overhead? It would be a shot in the dark again, but maybe increase the intervals? in the timer formulae

With Qt 6 and QOpenGLWidget, none of them work, and I also see crashes.tomorrow I'm going to clone the classic presets... if the ones I was using arent already, I got from steam and/or ubuntu packages;
I was able to make qt6 work with v3 today, remember? I believe using visualizations2 branch.
Had to force QStringLiterals all over the place to make it run, but perphaps with your fixes today it wont be necessary anymore. It was mainly paths: fontfile, preset, texture, etc;Its good try to test with the same suite of presets, obviously.
Its very nice that you advanced making v4 work at all! I need to rest, but tomorrow I'm going to test both visualizations latest and visualizations2 if necessary.
tkssssss nice job
qt6 llibprojectM v3 with visualizations2 branchI found another "hint" for the puzzle, on the qt frontend of projectM repo

Hope it helps; we can use QOpenGLFunctions.h for that procedure. Maybe this is just whats missing for us now in terms of black/blank screen............................

after making lotsa tests with this idea of "preparing" opengl I've decided to debug the preset loading, it seems something is wrong with the "current" preset, it never starts. I did some serious qLog debugging messages, it appears that it loads the presets correctly but the playlist never starts, not even the M logo. tomorrow I'll try to understand this better....

I've made a much more minimal test project here for debugging:

https://github.com/jonaski/ProjectMTestAwesome idea! Without v4, I always get these errors both in Strawberry and also now in the testproject:
~/ProjectMTest/build$ ./projectmtest No Textures Loaded from "/usr"/share/projectM/textures Could not open font file:
What I'm doing to bypass it is kinda bizarre.
mkdir -p \"/usr\"/share/projectM
for the first error, then I copy stuff to that bizarre new local dir.
For the fonts, I just force the filename to some ttf in /fonts with QStringLiteral and .toStdString(); in the settings s structure, vars are menuFontURL and titleFontURL
I really do not understand where this double quotes come from, neither why I'm having to set the fonts filename by hand. Do you think maybe v3 is trying to read from a config file i do not have?
-
its hard-coded on my lib from Ubuntu package
I'll see if it fixes by recompiling it by hand
