score VS gsequencer

https://ossia.io uses widgets and qgraphicsscene for the main UI rendering and Qt rhi for the GPU pipeline, and it's performing well enough for our use-cases - I was working on it on a 1080p screen on a Pi4 recently and it certainly felt much much faster and responsive than chrome on the same hardware.

I use it for live c++ recompilation in https://ossia.io - all the code is in there. https://github.com/ossia/score/tree/master/src/plugins/score-plugin-jit/JitCpp

> I feel like visual programming gets a bad rap because of things like this. As an electronic engineer that used to love LabView and life long user of NI Reaktor and Max/MSP, those tools are fantastic if you don’t approach them with an imperative programming mindset.

aha, in the long run I ended up making https://ossia.io which is as VPL as it can get. Yet it still embeds a LOT of textual languages.

For me both VSCode and CLion lag heavily.. whenver I tried CLion it was completely unuseable on my project https://ossia.io which is only 500kloc (and I try to try it pretty much once a year since it was in beta)

https://ossia.io does some of it, I've been working on a new release that also supports the whole QtQuick stack in the node graph items but you can already combine videos & shader effects

In https://ossia.io with PCH, using clang, ninja, mold, and some artificial split in shared libraries for development builds, I get a compile-edit-run cycle of a couple seconds in general... I wouldn't say it's too much of a problem if you use the tools already available

If you're interested in multimedia https://ossia.io is always looking for new contributors!

Tools like Ossia Score, Chataigne and PureData (pd) can also help a ton in building interactive art and triggering other A/V software.

here's a simple example of how to do it in https://ossia.io score : https://streamable.com/wkklek
