Passthru HDMI streaming in custom Tv-Input-App

[mustaphakd]

Greetings,

I don't know if this is right place to ask,

but I want to know if at all possible and how to go about accessing the local HDMI input on my personal AndroidTV and streaming it thru my Tv-Input-app.

I am aware that the scenario mentioned above is probably not possible as a third party app being installed on someone else androitdTv; but is it possible is I sideload the app into my personal Android TV ?
