3D FP can be tested manually currently, but obviously not suitable for prime time. In short:
Enable FP:
echo 3dfp > /sys/class/amhdmitx/amhdmitx0/config
echo 3doff > /sys/class/amhdmitx/amhdmitx0/config
Enable FP support via decoder:
echo 1 > /sys/module/amvideo/parameters/framepacking_support
Put us in an FP mode for HDMITX
echo FAKEVIC > /sys/class/display/mode # force reset
echo 1080fp60hz > /sys/class/display/mode
The problem is this isn't going to work on a lot of devices. When AMLogic added checks for Dolby Vision, they disabled 3D signalling in hdmitx. DV and 3D use the same registers.
I was able to fix this with https://paste.osmc.tv/raw/elevutajev, but who knows if a lot of Android boxes will ever see an update with a fix from AML. This patch also fixes 3D autoswitching (and is why it hasn't been working properly for some time) for other files such as SBS files.
Is this still a valid method to test frame packing 3D output on the Vero 4K?
