I had experience of building normal web apps for desktop and mobile before, and want to create my own video web app (similar to Youtube TV) on cross platforms, e.g. Smart TVs, game consoles.
I heard of Cobalt recently and all I know so far is a lightweight browser that we could run web applications using a subset of HTML/CSS/JS on it.
I also read the documentation of Cobalt (https://cobalt.dev/) but I'm still confused about it. It seems that Cobalt could be built only on Linux or Raspberry Pi. Could anyone provide some tutorial or explanation about how the development process looks like?
