I need little help with a project…
Question: how can I switch between two HDMI signals that go out to television with a help of raspberry pi?
Background (why i need this):
I’am really glad I found your project:
“Put friends and loved ones on the big screen with this instant video call project”
It was a long long wish of mine to implement such thing for my grandma. She spends most of her time in bed before TV… It would mean a world to her to be able to call me up or other people for a video chat.
I need help figuring out two things to make it work for her:
1. how to switch between two hdmi signals with a raspberry pi (to signal where the video chat will be shown, and back to her regular TV signal when the video chat is over)
2. how to initiate this call via Alexa (hey alexa, make a call to bob) (i ask this in a different post trigger video call on raspberry pi via alexa/google nest)
