mitmproxy support/How to install CA Certificate?

[Reis]

Hi. I recently rooted my TV (UE40F6650) to remove ads from the YouTube app. The most logical solution (I think) would be to use a MITM proxy to overwrite YT JS files to modify JSON.parse. Here's an example: https://github.com/FriedChickenButt/you ... ock.js#L76.

How can I install a CA certificate and make the TV connect to a proxy? Any help is appreciated.
