Reintegrate projectM Visualizer

@Gustavo-L-Conte
short is the same as int16_t, 2 bytes because the consumed buffer is 16 bit, but size_t is 8 bytes, I'd like to understand why that is correct.
Another thing is that channels are hard-coded, so if the buffer has more then 2 channels, it will be wrong so we should pass channels to ConsumeBuffer -
@jonas I really tried to understand that. I did put size_t because I saw somewhere that map.size type was size_t in gStreamer
The channels I tought it wouldnt be an issue, but thinking about it, it is.
###GstMapInfo
A structure containing the result of a map operation such as Memory.map. It contains the data and size.
struct GstMapInfo { GstMemory* memory; GstMapFlags flags; ubyte* data; size_t size; size_t maxsize; void*[4] userData; void*[4] GstReserved; }its not the buffer, its the SIZE of the buffer, thats why its not 16 bit like the buffer itself!
Maybe thats why -

Just found this, maybe useful

if (projectm_) { projectm_->setShuffleEnabled(false); projectm_->selectPreset(index, true); projectm_->changePresetDuration(1); projectm_->setPresetLock(false); projectm_->selectPrevious(index); QTimer::singleShot(1250, this, [index,this]() { projectm_->setPresetLock(true); projectm_->changePresetDuration(duration_); projectm_->setShuffleEnabled(true); }); }Here's an improved version 0.1b to prevent altering shuffle globally in the settings. But don't forget to set smoothPresetDuration = 0 in the settings, this is required.

MilkDrop was heavily Windows-based, implemented with DirectX, Win32 APIs, and assembler. ProjectM did a good job of replicating the functionality in a cross-platform manner but one DirectX-specific piece remains: the shader code in the preset files. Some presets can contain GPU shader programs as mentioned previously. Because they were written for MilkDrop, they are in HLSL, a shader language for DirectX. Support for HLSL was provided in projectM by NVIDIA's Cg toolkit, but that has long been deprecated and is unsupported. Either manual or automatic conversion (possibly using something along the lines of HLSL2GLSL for Unity) needs to be added along with code to compile and upload the shaders. This would greatly increase performance and capabilities, enable the most advanced presets, and drop the dependency on an out-of-date and unsupported proprietary framework.I saw on some presets some kind of shader language. The ones that bug!
-
in time, i just saw initializeGL with only BLEND command. All of those are required!!! Sorry if I did not express myself correctly. BLEND does the trick for the blank/black screens, but some visual bugs happens in lots of presets without the complete set.
glShadeModel(GL_SMOOTH); glClearColor(0, 0, 0, 0); glViewport(0, 0, width(), height()); glMatrixMode(GL_TEXTURE); glLoadIdentity(); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glDrawBuffer(GL_BACK); glReadBuffer(GL_BACK); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glEnable(GL_LINE_SMOOTH); glEnable(GL_POINT_SMOOTH); glClearColor(0.0F, 0.0F, 0.0F, 0.0F); glLineStipple(2, 0xAAAA);ALSO, you need to run the commands always before renderFrame, at drawBackground method.

Now, here's another one to worry about:
A few days ago I installed those newest cream-of-cream set of plugins. Awesome by the way.
They seem all working fine. I spent days testing on random mode. I still want to compare one by one with the SDL app.Now, problem is, when I go to the select visualization window, all the previews gets bugged if The first ones of the list (mostly called "Fast transition..") are selected. They don't seem to be normal plugins. Anyway, Thing is, if you select for preview any of these first ones, it bugs all other subsequent plugins. glClear color is not black anymore and they render all dumb. Only restarting Strawberry for normal behaviour again.
Gonna look at the milkdrop code, later, to compare the "normal" ones from these "Fast transition..." ones.

@Gustavo-L-Conte
Thanks for looking into it. It seems that projectm version 3 is buggy, I think we should try to get version 4 working instead, and drop support for version 3. See the discussion on https://github.com/orgs/projectM-visualizer/discussions/820 -
@jonas roger that, gonna go back focus v4
By the way I did compile latest git from v4 with his fixes, and tested with branch visualisations, did not work, same results. I'm curious about QOpenGLWindow results, with his fixes. -
I had success starting to display stuff with v4 using QOpenGLWindow in a separate, smaller program. Soon I'll upload the code, I just need to adjust some things like resize and OpenGL context. I've used as ConsumeBuffer the pulseaudio capture code. I just need to adjust some stuff i think to make it better, but i got so excited about a positive display in v4 that i wanted to share ASAP
LoooooooooooooooooooooooooooL!
PS: still, several GL error 1282 in the majority of presets tested.
while some actually works
-
the FPS on the video is very low due: * frameskipping at the desktop recorder
- fps was set t o 10 fps for testing purposes on projectm instance

I'm probably NOT the founder of the I.O.G.L.N.U.S.A.H.A.
Tthe International Open GL NEVER Ugonna SLEEP AGAIN ha ha ha Society.
Decided to go ahead and do the QOpenGLWindow on Strawberry.
Its worse than just the standalone program. Much more bugs. But the few that works are incredible. We are close. Here's what I've been messing around with my IogLnusaha association (I'm on Gnomes)

ITs not a matter of context, but its like a corruption happens when you wrap.
I could manage to bind key_S to open the visualizations selector, when setting as central, because I could not figure out why the overlay and interface don't work
-
this version I posted works MUCH better giving nice results with the cream-of-cream presets,
-
void VisualizationOpenGLWidget::paintGL() { QPainter p(this); p.beginNativePainting(); int w = width(); int h = height(); this->resize(w*2,h*2); if (projectm_visualization_) { projectm_visualization_->Resize(w*2, h*2); projectm_visualization_->RenderFrame(w*2,h*2); } update(); this->resize(w,h); if (projectm_visualization_) { projectm_visualization_->Resize(w, h); projectm_visualization_->RenderFrame(w,h); } update(); p.endNativePainting(); qLog(Debug) << __PRETTY_FUNCTION__ << glGetError(); }Its disgusting, but it really makes a HUGE percentage of presets to display instead of black screen.
Ive done this without wraping the openglwindow into a widget;
when you resize the window, it displays, several plugins happens that way.. actually the nicer ones like this one:

I'm trying lotsa stuff, using FBO and OpenGLWindow, changing profiles (between versions and compatibility/core), I even made an SDL2 window version. Every time I implement a different way, All result are the same: some presets working and the same majority not working.
But now I've tried bypassing the normal way presets are loaded, and only use this, i.e.
projectm_playlist_add_path(projectm_playlist_instance_, "/home/guzpido/presets-cream-of-the-crop", true, true);it appears to make a bit more presets to work. this could be a clue. Maybe the way we are loading presets has some issue; but I've banging my head to figure it out if this makes even sense.
edit: also i cant determine if ConsumeBuffer is working
-
I finally understood the mystery of why size_t is accidentally working in ConsumeBuffer: all my FLACs are S24LE, I just tested now one of my own songs which are S16LE and the correct int16 aapproach works for detecting and interacting audio with visuals! Therefore Im trying now to make a ConsumeBuffer with lasers to determine automatically the format and width: (but no luck making S24LE to work)
#include <QtCore/QtEndian> void VisualizationSDL2::ConsumeBuffer(GstBuffer *buffer, const int pipeline_id, const QString &format) { Q_UNUSED(pipeline_id); GstMapInfo map; gst_buffer_map(buffer, &map, GST_MAP_READ); if (projectm_instance_) { unsigned int sample_count = 0; const int16_t *int16_data = nullptr; const float *float_data = nullptr; if (format == QStringLiteral("S16LE") || format == QStringLiteral("S16BE")) { sample_count = map.size / sizeof(int16_t) / 2; int16_data = reinterpret_cast<const int16_t *>(map.data); if (format == QStringLiteral("S16BE")) { // Convert big-endian to little-endian if necessary std::vector<int16_t> temp_data(sample_count * 2); for (unsigned int i = 0; i < sample_count * 2; ++i) { temp_data[i] = qFromBigEndian(int16_data[i]); } int16_data = temp_data.data(); } projectm_pcm_add_int16(projectm_instance_, int16_data, sample_count, PROJECTM_STEREO); } else if (format == QStringLiteral("F32LE") || format == QStringLiteral("F32BE")) { sample_count = map.size / sizeof(float) / 2; float_data = reinterpret_cast<const float *>(map.data); if (format == QStringLiteral("F32BE")) { // Convert big-endian to little-endian if necessary std::vector<float> temp_data(sample_count * 2); for (unsigned int i = 0; i < sample_count * 2; ++i) { temp_data[i] = qFromBigEndian(float_data[i]); } float_data = temp_data.data(); } projectm_pcm_add_float(projectm_instance_, float_data, sample_count, PROJECTM_STEREO); } else if (format == QStringLiteral("S24LE")) { // Handle 24-bit audio (3 bytes per sample) sample_count = map.size / 3 / 2; std::vector<int16_t> int16_samples(sample_count * 2); for (unsigned int i = 0; i < sample_count * 2; ++i) { int16_samples[i] = static_cast<int16_t>((map.data[i * 3 + 2] << 8) | map.data[i * 3 + 1]); } projectm_pcm_add_int16(projectm_instance_, int16_samples.data(), sample_count, PROJECTM_STEREO); } gst_buffer_unmap(buffer, &map); } gst_buffer_unref(buffer); } -
@Gustavo-L-Conte
Are you still working on the projectM integration, or did you give it up? -
@jonas I would not say that I completely gave up, but I just started a new position in a company so I lost that whole free time to mess with this particular thing
I went making https://github.com/guprobr/WakkaQt instead to learn a bit more Qt before resuming this task
The last ideas we discussed, I never tried... but the last post on projectM made me feel second toughts on the viability of the idea.... anyway, i want to resume this task someday I don't think we should give up but certainly something is missing in the backend inner parts of how Qt works with OpenGL and how projectM works with OpenGL, as it was discussed on the thread on github.But the first thing i would do is trying with latest Qt LTS, before anything.
Second thing, to try with the same version on Windows!
We have to figure where the problem is. Obviously its a Qt issue, but what made me stop working on it was when SDL window version showed the same issues. That was very disappointing.PS: sorry to take so long to answer, I just saw this today
