Hi
I want to use all available overlays with nvoverlaysink.
Currently I am able to use only one overlay = 1 .
How may overlays are supported in tx2 ?
Way to enable these overlay ?

Setup :
Jetpack 3.3

I use this script to assign the 6 overlays to fb0. I use this for displaying a mosaic of 6 cameras to HDMI.

#!/bin/bash

# This script assigns the 6 available overlays to fb0


cd /sys/class/graphics/fb1
# turn off display
echo 4 > blank
# disable all overlays for the display
echo 0x0 > device/win_mask

cd /sys/class/graphics/fb0
# turn off the display
echo 4 > blank
# disable all overlays for the display
echo 0x0 > device/win_mask

# Assign all 6 available overlays to the display
echo 0x3f > device/win_mask

# Turn the display on
echo 0 > blank

Hi
I followed the procedure from below link to enable overlays and it works as expected.
