Want to help get this working again #12

Are the issues in this repo reflective of what has to be fixed to get back to a functional app? Would like get this working again so please know how I can help!

I expect some changes are needed to support the new 4.x API Welcome to come chat with us on Discord I'm working on https://github.com/projectM-visualizer/frontend-sdl-rust with SDL3

More or less, I'd say.

The main things requiring work would be:

Updating the projectM integration to use the new 4.0 API, as Mischa said. That's not hard to do. May either use the new playlist library, or just manage preset switching in the Qt app itself, as it already has its own playlist functionality.
Making audio capturing more portable, e.g. by using a wrapper library such as PortAudio.
Updating the whole Qt code to work with the most recent Qt 6 versions, including making proper use of QOpenGlWidget.

No one I know of is currently working on the codebase, so feel free to take it over. We'll answer questions and review PRs!

I would argue that #1 is the most important since it gets back to functional again if that's completed.

kblaschke commented 1 year ago

Absolutely. Third one is also important, as the application exposed weird rendering issues last time I've worked on the Qt 6 upgrades. These might now be mitigated by rewriting the rendering process in libprojectM. From what I could see in RenderDoc it was an issue that some (not all) VBOs/VAOs initialized at preset load time were already lost when rendering a frame, but they weren't actively deleted by projectM.
