Anyone having Broken Video Orientation problem of videos taken in portrait mode (like from smartphones)? Videos plays 90° CCW, but stretched vertically.
I will try it today.

On my, NanoPC-T4 with the image of balbes150:
LibreELEC-RK3399.aarch64-9.1-devel-20190412110938-68723cf-khadas-edge
and my DTB
this behavior also occurs.
I'm sorry

I just wanted to chip in on the 4K issue. I've taken a look at getting a fully working device tree for LibreElec before, and I can confirm that the I2C communication on HDMI is broken when I checked last september. I wanted to get CEC working, but it seems that with FriendlyElec's default settings the wrong clocks are set. This prevents the T4/M4 reading the screens EDID and therefore only showing 'safe' frequencies and resolutions.
Now that the 5.x device tree files are in mainline Linux, maybe I can see what they changed in this regard and backport it to the current LibreElec builds.

That would be great.
I already miss CEC.
Good luck and it would be nice if you would share your successes with us here.
Best regards

Great news everyone, Official Kernel support for the NanoPC-T4 is starting from v5.1 ([v2,11/14] rockchip: rk3399: Add Nanopc T4 board support - Patchwork). I hope when Kodi updates to it, we will see official support from LibreELEC as well and nightlies will start rolling.
Let's hope for the best here

I'm having another issue. When ever I'm streaming video files either from the Internet, YouTube or local network, when then video caches sometimes the video gets stuck and audio keeps playing.
I have the same issue. But specially with 4k content

Hello, so i have a question around this point. Is there no way to somehow "disable" the safe mode feature, or better force it to use 33840 x 2160?

Is there already an image of LE with kernel 5.1 for NanoPC-T4?

No, one I'm using is the Rock960 image with dts extracted from GitHub - mrfixit2001/recalbox_rockpro64: Recalbox for the ROCKPRO64 board from PINE64.org
It's still on Kernel 4.4.154

That's just like me.
I use the Khadas-Edge image with the same DTB file from Recalbox.
Yesterday I tested the test image (kernel 5.1) of Kwiboo.
It already works fine and under kernel 5.1 the NanoPC-T4 is natively supported, so there is also a DTB file.

Where did you find the images?

You tested the dtb with which image? One from Index of /? Was the Wi-Fi working, because without it I would have no access to it lol

I used the following image of Kwiboo:
libreelec-rk3399.arm-9.1-devel-20190512180245-bdfaff1-khadas-edge.img.gz
with the nanopc-t4.dtb file from:
http://http//kwiboo.libree…245-bdfaff1.tar
As Kwiboo wrote under his posting, Wifi and BT so far only work on the tinkerboard.

Known issues:
- Only up to 1080p resolution and not all refresh rates
- 10-bit videos will show as green picture
- SW decoding of VP8 on RK3399 produce garbage
- Hotplug of USB3 on RK3328 only work one time, a reboot is required to discover a new/replug usb device
- No AC3/DTS/HD audio
- No WiFi/BT (wifi should work on tinkerboard)
- No deinterlacer
--snap
So we still have to practice patience.
