[8.2.2.3] LibreELEC 8.2 for S912

Quote from kmxak

does anybody know how to fix lan speed problem? i used static ip and dhcp both the same.

LAN speed is no problem in LE - check Your network first

A good test is using iperf

thats le output

i enabled debug and the screen starts stuttering when kodi cpu is over 100%

Fast ethernet should look like this:

Did You try iperf running on other devices like PC, Notebook, NAS etc. ?

i am moving large files to my storage server from different clients all have arround 90-110 mb/s

not tested with iperf.

.. this is solved now.

but stuttering is still there.

i tryed some buffer settings and now its better but not perfekt.

I see the Video buffering but when the video continues the buffer is gone and loading again. its a bit crazy

First thing to do in this case:

connect external HDD directly at the box and check it out

I tried another dtb file, the 2Gb version did not work. I could not boot up LibreElect. I tried both 100bit and 1Gbit ethernet.

I even tired not having a DTB file at all, boots up but still no internet connection or valid IP address.

When I tried the 3db 1 gbit dtb file, I do get a valid IP address but does not connect to anything. I test by adding more weather providers and by connecting to my NAS but can't located. Very frustration.

Hi all

I wonder if it is any add-on I can use to change or monitor the video chroma subsampling output. 4:2:0 or 4:2:2 or is LibreELEC always sending

no subsampling at 4:4:4 ?

If so. Is LIbreELEC sending full RGB 4:4:4 0 - 256 or Y'CbCr 4:4:4. 16 - 235 ?

I have the MInix u9-h device with latest LibreELEC installed.

I think I got this, run this to see what your device is capable of

cat /sys/class/amhdmitx/amhdmitx0/dc_cap

then just cat what you want in.

echo 'rgb,8bit' > /sys/class/amhdmitx/amhdmitx0/attr

echo '444,8bit' > /sys/class/amhdmitx/amhdmitx0/attr

echo '444,10bit' > /sys/class/amhdmitx/amhdmitx0/attr

Silly question but are you renaming the dtb to dtb.img when you are trying them.

No silly questions here, yes, I'm renaming them to dtb.img

Hey, guys. New owner (several hours and counting) of a U9-H running 8.2.2 on internal (no desire for Android).

Seems to working great so far. Huge improvement over the SATV with its poor upscaling.

One thing minor thing I'm seeing with this device is that the Kodi UI only detects 24/23.97 at 2160p. No problem running the UI at 1080p/60hz which looks great. I know the AVR port supports 2160/60 because I had the SATV on the same port and it had 2160/60 working. Should I be seeing 60hz as as an available refresh rate for the UI or does this build of LE not support it? I've rebooted the device with the AVR/tv on so it should be detecting EDID modes.

1080 mkvs look great (best I've seen since getting the Sony X900e. 4k/HDR also looks great and very smooth. So it seems like the auto resolution switching is working. So it seems like no actual problem with watching videos, just the UI (not that I have any 4k/60Hz in my library).

Thank you Kszaq for all your work on this. Definitely the best Kodi box I've had.

***Nevermind. swapped HDMI cables and now the UI runs in 4/60hz. But still, thanks Kszaq!

Hey guys, been successfully using the KM8 Pro with LibreELEC - thanks kszaq!

However, I'm not having much luck with getting sleep/wake to work. I've enabled the sleep function in the config file mentioned earlier in the thread via SSH, but I'm not sure how to go about waking the device after it goes into standby (when the front LED is red). I've tried sending remote commands with HDMI-CEC and Bluetooth, but neither can wake the unit up; I have to press the front button 'on' to wake it up.

Does that mean this box probably just doesn't support sleep mode?

Quote from kszaq

These boxes cannot be woken up using CEC or Bluetooth. Only IR and power button (and some WoL when enabled in bootloader).

Hi,

I use a mx3 remote which works great. But there is 1 small problem. My 4 year old son sometimes accidently hit the red power button and than the box immidiately powers off. I want to disable the power button so when you press the button nothing happens. I think the red power button is an IR button (the other buttons are rf buttons) and I can not remap or disable that button.

Is it possible to put the box in suspend or sleep mode when the power button is pressed? That would solve the above for me.

Thanks.
