Aha! Null problemo and thanks for finding and adding more data to the issue.

As I said, it's likely a bug. And what you should do with a bug is report it on GitHub so that this Robert guy doesn't forget to fix it.

I think that's actually a bug in Kha as you'd normally wouldn't do it this way. You'd instead just call g.drawIndexedVertices(0, 6);
What target are you using?

Hello folks,

as an alternative to this forum you can now also use GitHub Discussions at https://github.com/Kode/Kha/discussions and https://github.com/Kode/Kinc/discussions
GitHub Discussions is still in beta so we will see how it turns out but long term I think/hope it will replace this forum. For now please use whatever you prefer and if you decide to use GitHub Discussions please look out for whatever you might find useful to report back to the GitHub Discussions team.

Best regards,
Robert

Videos are supported in shaders and that's where you can also apply chroma-keying (you can search the forum for instructions on how to do that).
Camera feeds are supported using kha.capture.VideoCapture API but that hasn't been implemented for mobile targets so far.
No speech to text, also no plans to add that.

Hm, the makefile doesn't seem to do anything special. Looks to me like you should bring up this issue with the emscripten developers.
I use WSL for emscripten development by the way because the whole emscripten toolchain seems to be more at home on Linux.

Looks like an emscripten setup issue, it can't seem to find your python.exe. Can you compile regular emscripten projects?

PS: And as you're saying python is at that path - maybe it needs to use a cygwin style path (/cygdrive/d/...). But anyway, get regular emscripten projects going first.

Hmm, yes, that's definitely important. Please open a GitHub issue, will try to get that in soon.

Ah, that tells us what's going on. Electron (which is used to run html5-debug builds) can not enable WebGL on your system (might be a black-listed driver or whatever) and then loading shaders of course fails.

But that works fine for me. Can you show me the complete build output?
