Hi unninair & cobrien,

Confirmed we can run the video with two hdmi output without tearing issue.
List our test steps for you reference.

  1. Add Option “TegraReserveDisplayBandwidth” “false” to your xorg.conf (#22 Wayne’s command)
  2. sudo service lightdm restart
  3. Set win_mask
#cd /sys/class/graphics/fb0
# echo 4 > blank
# echo 0x0 > device/win_mask
# echo 0x3 > device/win_mask
# echo 0 > blank   
#cd /sys/class/graphics/fb1
# echo 4 > blank
# echo 0x0 > device/win_mask
# echo 0xc > device/win_mask
# echo 0 > blank
  1. Run below commands
gst-launch-1.0 filesrc location=file3.ts ! tsdemux ! h264parse ! omxh264dec ! nvoverlaysink display-id=0
