Firstly I like to say I dont watch TY so I am not planing to record tv shows.
I am using my TV as monitor for nearly everything and I like to take screenshot or even record small videos of gameplay from Nintendo classic mini or PS2.
I have done some research and I can only find app that records show or external hardware like elgato, but I dont have the economy for that kind of hardware. I also did some research on if it was possible to make a raspberry pi a video capture device with a hdmi input but that option is also fair expensive because of a special hdmi to csi-2 bridge chip I would need to import.
I also learn that I could plug a usb stick for extra storage into the tv but it would be unreadable on other devices so I quickly skip that option.
I hope someone have a answer. It is just for a home project to keep my mind sane during these lockdown times. Thanks for your time.
PS. my tv is a KD-55xf9005 running android version 8.0
