SOM-RK3399 Android HDMI-In Camera

Moderators: chensy, FATechsupport

I am trying to use the HDMI input on the SOM-RK3399 in Android 8.1. Is this possible? I was under the impression that it would show up as the default camera in Android.
I wasn't seeing anything on the camera preview. Turns out my camera was in Auto-Detect HDMI out mode. Changing it to output 1080p explicitly fixed my issue. But this brings up another question. Does the HDMI in port have EDID capability?
