Is it possible to pass through from USB to HDMI in Raspberry Pi Zero W?
I need to pass through video/data from my laptop to TV Monitor through Raspberry Pi Zero W while capturing passed data in Raspberry Pi Zero W.
My laptop(HDMI out) ---> (HDMI in) HDMI video capture with adapter (micro USB) ---> (micro USB) Raspberry Pi Zero W with saving to external storage (mini HDMI out) ----> (HDMI in) TV monitor
The expected resolution and frame rate: up to 1080p and up to 120HZ (but it can be less, it doesn't matter for now)
HDMI video capture: something like this - https://www.amazon.com/FURUI-Capture-USB2-0-Camcorder-Compatible/dp/B08911TVP9
How can I do this?
I tried this solution:
I can see laptop screen, but without sound.
cvlc v4l2:///dev/video0 :input-slave=alsa://hw:2,0 solved my problem
But, maybe somebody can suggest an another way? How can I set parameters for optimal quality of video?
