Hi everyone,
Now I try to test HEVC 4K60fps on Jetson TX2. My gstreamer pipeline
gst-launch-1.0 filesrc location=test.mp4 ! queue ! qtdemux name=demux demux.video_0 ! queue ! h264parse ! omxh264dec ! nvoverlaysink sync=false -e
On the console, it shows
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

However, the output on display is slow; not 60fps.
How can I change the HDMI ouput to run with 4k@60fps?
Thank so much.
Quang_OpenStack,
Could you dump the value of below node?
sudo -s
cat /sys/class/graphcis/fb0/mode
Dear WayneWWW,
There is error "cat: /sys/class/graphcis/fb0/mode: No such file or directory "when do
sudo -s
cat /sys/class/graphcis/fb0/mode
However, I got this messge when do “sudo cat /sys/class/graphics/fb0/modes”

It seems that I need to add 3840x2160@60fps to the HDMI output?
Because when I do “DISPLAY=:0 xrandr” it shows that HDMI output does not support 3840x2160@60fps yet.

Do you have any suggestion for me because I try to use xrandr to modify output rate but it does not work with nvidia driver?
Quang_OpenStack,
If xrandr does not show 4k@60 mode in list, it means tegra dc driver does not support it and filter it out. Or just your display does not support 4k@60 at all.
Dear WayneWWW,
I am sure that my display support 4K@60fps, it can run well with other 4K@60fps source.
Is there anyway to make TX2 dekit’s HDMI output change to 4K@60fps?
I try to add 4K@60fps mode with xrandr as following but it does not work
http://ubuntuhandbook.org/index.php/2017/04/custom-screen-resolution-ubuntu-desktop/
Thank
Tegra x11 driver does not accept user to add arbitrary mode. It only accepts valid mode from edid.
Please share your display EDID. Some debug method is in this wiki: Jetson TX2/r28 Display debug - eLinux.org
Dear WayneWWW,
My EDID come out when do “cat /sys/kernel/debug/tegradc.0/edid”

Could you also add below option in /etc/X11/xorg.conf? more log will be shown in /var/log/Xorg.0.log
Option “ModeDebug”
Please also share this log.
I add Option “ModeDebug” into /etc/X11/xorg.conf as your recommendation.
The attached files is log.

It is weird. I see your monitor has 3 3840x2160_60. 2 modes are YUV mode and thus rejected by tegra. However, the remaining one should be listed in xrandr. Could you share what LG tv you are using?

Dear WayneWWW,
I test with [LG] webOS TV OLED 355B7K and [Samsung] QN55Q7FAM. The same problem happens.
When you check more on log file I find that

Also, I only can connect HDMI cable with LG TV after finish booting; if not TX2 cannot finish booting.

Quang_OpenStack,
According to your statement, it is more like an old issue we hit in previous release(rel-28.1). Please follow L4T document in below link. (If you are using rel-28.1)
