vc_cec_*
▪ rpi-output-swapper (https://github.com/adammw/rpi-output-swapper) Uses
tvservice apis to power on HDMI or SDTV display in specific or preferred mode.
The vc_cec APIs allow programs to interface with the Consumer Electronics Control
(CEC) (http://en.wikipedia.org/wiki/Consumer_Electronics_Control#CEC) host

callbacks.
