    Hi, could you please reply to my previous post?

    I'm having a hard time figuring out which kernel your build uses. Is it based on kszaq's builds?

    The automatic REC.709 and BT.2020 switching, does it normally run in 422,8bit and only switch to 422,10bit when HDR content is started?

    That would be perfect, because my TV switches into BT.2020 SDR mode when I run it at 444,10bit, which oversaturates everything.

    Also, can we expect a S905X build?

    If you use:

    echo "echo '422,10bit' > /sys/class/amhdmitx/amhdmitx0/attr" >> /storage/.config/autostart.sh

    You will get green screen video output with kszaq's LE 8.2.x S9xx AML builds because that uses the old AML Linux Kernel that has a bug in it.

    Those sort of terminal commands are only needed if you are watching 4K HDR 10bit video anyway.

    With the old kszaq Kernel you actually use this command for proper 4K HDR Chroma and 10bit output:

    echo "echo '444,10bit' > /sys/class/amhdmitx/amhdmitx0/attr" >> /storage/.config/autostart.sh

    A high speed or premium certified HDMI 2.0a cable is then needed because you will be transmitting a lot more 4K HDR display data over HDMI.

    Some people (like hdmkv) have 4K HDR projectors that only support 422,10 or 12bit input - so this was the reason I plugged in the newer AML Linux Kernel in the first place - to fix the 422,10bit green screen issue.

    Thank you wrxtasy for this information.

    Is the command line in autostart.sh going to be there permanently even after I have turned off the

    U9-h ?

    Wizzi07 it might be some sort of issue with a device tree. You might find newer compatible ones in the .img device trees folder included in the following post:

    [8.2.2.3] LibreELEC 8.2 for S912

    If your device is cactus see the Freaktab forum and reflash Android Firmware with the USB Burning tool software:

    S912 - FreakTab.com

    Of course you will have to flash the image first to a SD card to access the device tree directory.

    ok thanks! I’ll give it a try

    wrxtasy .. I created a new bootable sd first using kzsaqs build and dtb and it booted so I placed your 10bit version into the update folder rebooted and it updated and got passed the mecool boot screen and onto the Libre elec screen with your build name in the top left corner, the image then goes small and into the top left then the screen goes black and the tv detects no input.

    The tv is definitely 10 bit capable it’s a panasonic 65dx902b

    Any idea what I could be doing wrong?

    Thanks

    I use LE-8.2.2.3 with my Alphawise H96pro+ (S912) and for me works all things fine.

    I have tested the new LE-8.90.5 but without success to play videos or LiveTV with 3840/50p. And so I use these "older" LE-8.2.2.3 version.

    With the LE-8.90.5 I have to use "ir-keytable" for my remote control and this is really great, because I can use my Universal Remot control after create a "keytable". And this works perfect!

    And for this reason I would like the same with LE-8.2.2.3, so I can use my Universal remote control in place of the original remote control, but it doesn't work. What have I made:

    • In the Libreelec-addon I have deactivatet "lirc"
    • I put my, under LE-8.90.5 created, "rc_maps.cfg" to .storage/config and also my createtd "keytable" to .storage/config/rc_maps

    After a reboot I found out that my Universal remote control doesn't work.

    • If I logged in the console and put in "ir-keytable" I get only an error message: "/sys/class/rc/: No such file or directory"

    And so I have a question: Is there a possibility to use ir-keytable with LE-8.2.2.3 or can I only use "lircd" with this LE version?

    If YES, can you say what I have to do.

    PS: Sorry for my english, but this is not my native language. ;)

    the earlier versions, used a different way for the remote.

    Create remote.conf from scratch

    remote.conf repository

    you basically create a remote.conf & put it in the config folder

    I have a logitech 350 & 650, if you look through the posts, there are some instructions there, to use the Pivos profile from the logitech database

    Hello

    I cannot access the 512mb partition after burning the image to usb drive

    ive used rufus and libreelec writer.

    Im using windows 10

    What can i do to solve this?

    I assume you just want to put the correct dtb file in the 512 partition, I use windows 10, & once rufus has finished, the partition opens, so I can copy the dtb over

    Yes, that is also a way to use my Universal remote control with LE-8.2.2.3

    So I have to create a new "remote.conf" for LE-8.2.2.3 and can't use my "keytable" from LE-8.90.5.

    If there is no other solution I will do that at weekend! :)

    wont work on windows, i had to install opensuse to access the partition

    i copied the file but looks like my box is not compatible, i just ordered a compatible one

    lets see how it works :)

    Thank you bro.

    Notes:

    - there may be some Audio issues with this release after using audio passthrough. Straight 2.0 PCM audio is fine.

    - the previously jerky video playback when watching H264 OTA TV seems to have disappeared as well.

    Sorry to say, but the jerky video playback of 720p-TV channels (H264) has not been solved. Any ideas? Otherwise this is the best version for 4k HDR yet. Many thanks for your efforts!

    With LibreELEC-S912.arm-8.2-Chroma-422.10bit.tar i have many skip frames (500) with x264 videos, back to 8.2.2.3 and its ok...

    Also i have small problems with 444 on 8.2.2.3 (black screen with 1080p videos once per movie for 1 second), no signal on 420 and green screen on 422.

    On RGB 10bit its looks good but is rgb better or worse then 422?

    Green screens when using 422 have been verified fixed by a few of use now when using the new Kernel. I cannot help with @kszaq's LE 8.2.2.3 version, but black screens when using 4:4:4 are usually a sign of a HDMI cable unable to transmit up to 18Gbps of data.

    Have you set a fallback framerate in Kodi > PVR & TV > Playback settings ?

    Mine is set at 50Hz for 25fps TV viewing.

    This is the current img.gz I'm using:

    hi I'm running the 8.90.5 rom on a beelink gt1. I got some occasional reboot. From what I've read it's related to temp sensor.

    In the 8.90.5 thread, op says in my case we should use 8.2 temp-sensor-disable from ksaq. Where can i find the temp sensor disable rom?
