Web/device camera input using Emscripten

[kapsyst]

I'm new to Emscripten and web development, and I'm looking for a way to:

• Obtain a standard camera device input buffer
• Convert it to an OpenGLES texture for further processing

I know that this should be possible, as I have witnessed several working examples doing so (including this), but I can't find any C/C++ source code that does so via Emscripten.

Intuitively, there should be a function in html5.h, but I can't find one. https://emscripten.org/docs/api_reference/html5.h.html?highlight=html5

I also understand that we can use getUserMedia as described here: https://www.w3.org/TR/mediacapture-streams/, but I can't find any equivalent Emscripten function.

I have searched all throughout the documentation, and around the web, but can't find any way to do this. Any help, pointers would be much appreciated.
