Request: Support for HDMI-CEC (turn on tv, switch hdmi)

[TOMillr]

Any progress on finally implementing support for HDMI-CEC right into Recalbox.

Among other things, CEC-support would allow the Recalbox-system to automatically turn on the TV and switch to the proper HDMI input. Or allow users to use the regular TV remote to navigate the Recalbox menus.

Kodi already has this code baked in and it works even when run from within the Recalbox build. Why not use that part of the code and extend it to Recalbox itself?

Here‘s a guide on how to manually add CEC support to EmulationStation on a Linux-based system. Maybe this code could just be incorporated into Recalbox and included in the settings menu similarly to how it‘s done in Kodi?

To provide some more technical documentation:

Support for HDMI-CEC is part of the Linux kernel since v4.8.

The CEC adapters made by Pulse Eight already support this and can work as a compatible adapter on x86/x64 machines.
