problem #1: HDMI output resolution
check hdmi-0 initial output resolution
sudo cat /sys/kernel/debug/tegradc.0/mode
result is 640x350, my dell monitor can not display it. out of range…
xrandr command can list hdmi-0 and dp-0 output supported timing from display controller of GPU.
hdmi-0 [my monitor does not support these resolution, so out of range…]
640x350 - 85hz
1392x1392 - 60hz
dp-0 [work normal]
1440x900 - 59.89hz
1280x1024 - 75.03hz
how to modify configuration file , to change hdmi-0 default output resolution ???
problem #2: under DP-0 environments, ffmpeg, gstreamer can not work!!!
DP-0 can normal display, but under DP-0 display, ffplay can not decode multimedia file.
error related to D-BUS, arguments to dbus-message_new_method_call() were incorrect…
under DP-0, gst-launch-1.0 neither not work like ffplay, does not launch imx219 or usb web camera.
my os image is jetson-nano-jp46-sd-card-image
