So far it was only implemented for html5. Normally you can extract pixels from a render target using Image.getPixels but I'm not sure it works with a camera video stream - but give it a try.

You'll need to fix that first. Sadly I can't really help you with that. Your Visual Studio installation seems to be messed up somehow.

stdio and stdlib are standard C headers. Can you create and build a regular C++ project with Visual Studio?

Aha. So, what are those errors?

Ah, you need to install the C++ support for Visual Studio, it isn't installed by default nowadays. Just start the Visual Studio installer and select it.

There is no slot1.sav file. I think the file Electron creates is literally called localStorage and it will include the contents of your slot1.sav as well as the contents of any other StorageFiles you create. Where localStorage ends up depends on your operating system.

No, but please open the Visual Studio project and run it from there so you can see where that happens.

In that case it's saved wherever Electron saves its local storage thing.

Call Storage.namedFile.

I don't know anything about Spout and/or Syphon but I know there are no tutorials about adding Kha to an existing engine - also don't think there ever will be, that seems to be more of a problem about any specific engine than about Kha itself.
