Yes tearing in the gui is very present in this build.

I installed this build on my mecool M8S PRO L.

I'm not seeing any completely obvious GUI tearing at 1080p50Hz on the U9.

Q. Have you overclocked the S912 GPU and verified it's running at 792MHz ?

cat /sys/class/mpgpu/cur_freq

EDIT: There may be a tiny bit if I look very closely at the bottom of the screen with some Kodi icons. It is no where near the really obvious tearing we had in early versions of LE for the S912.

Am I going to fix it - maybe.

So wrxtasy no idea why only your builds crash while opening livetv?

If you are watching 4K 50p HEVC TV and have a Chroma 444,10bit set that will not work because it's outside of HDMI 2.0 Specs.

It's why we need 422,10bit working without the green screen bug - because then you can use 4K 50/60p display modes.

Maybe VSYNC is completely broken in this build, due to an old version of Mali driver.

You would have really bad Kodi user interface tearing if there were no Vsync - exactly like we used to see in the early days of LE on the S912's before kszaq worked his hybrid GPU driver magic.

The regular Linux r5p1 Mali driver is not used at all on S912's - in the words of kszaq:

These builds (S912) use libhybris and Android gralloc Mali driver to provide OpenGL for Kodi

Thx. for the sample Pinki

I can now clearly seen video frame upsets happening about every 1 second with the external subtitles when played on the U9 (S912) using Hardware video decoding.

However my S905 ODROID C2 does not have any problems whatsoever nor does a MECOOL S905X box, both running LE 8.2.x and using HW decoding.

It appears only S912's that are using the Hybrid Android/Linux GPU drivers are having such subtitle, video frame upset issues.
Subtitle rendering is a GPU function.

We really need better optimised S912 Linux GPU video drivers to fix this LE S912 problem.

EDIT - good news S912 owners !

I've updated the kszaq modded Hybrid GPU drivers for the S912 and added an important VSync Hardkernel ODROID C2 patch:

I see no S912 Subtitle / video frame problems now playing the above test clip when using this LE 8.2.4 Kodi Krypton release:

LibreELEC-S912.arm-8.2.4-S912-Subtitles-fix.tar

The Kodi user interface seems snappier now as well.

W.

Standard way to run any 4K LE AMLogic box:

If you watch a lot of 25i OTA TV use a 1080 50Hz setup to prevent un-necessary refresh switching.

I watch a lot of 25i live TV with S912 MINIX U9 - LE v8.2.4 = no crashes.

Otherwise use a 1080p 60Hz Kodi GUI and let your 4K TV upscale everything with it superior 1080p > 4K upscaling Hardware. This will result in superior picture outputs.

AML LE Kodi Krypton will Auto Resolution Switch to 4K when actually watching 4K content anyway.

The CPU speed has (mostly) nothing to do with hardware video decoding or drawing the Kodi user interface, it's just idling most of the time. In that context consider whatever speed it is running at irrelevant.

Cheap AML hardware with cheap internal components and without proper thermal cooling and heat sinks - when Overclocked will very likely crash or show other strange picture output behaviors.

Time to open up and mod your device then like mirbg 's cool setup pictured above.

And yes there are extra Kodi settings in my releases found in System and also Audio settings. Hint set LFE to 100% for 2.1 subwoofer audio setups.

Current GPU clock Frequency:

cat /sys/class/mpgpu/cur_freq

I would only be worried if a S912 sits on sustained temps of 90+ Degrees C

That would indicated really poor SoC cooling and thermal design.

63 is pretty normal for a AML SoC.

Does this mean giving up wetek play2 ??

There are a bunch of new WeTek devices, officially licensed for Google Android TV - Operator Tier - where WeTek customise the device and ATV user interface for whatever a Pay TV / IPTV / STB operator wants. They are not retail devices.

You can see all the ATV Operator Tier, sellers listed here:

Which builds do you support for the U9?

The S912 build in the folder I just posted. It's for all S912 boxes.

As usual just pick the correct .dtb for your particular S912 box and rename to dtb.img for 792MHz GPU Overclocking usage.

This new S912 Krypton version in the following folder should fix the ppmgr_3d_mode error.

There are also new kszaq S912 compatible device trees that are needed for GPU Overclocking.

S912-Krypton-v8.2.4-AML folder

That is as far as my support for personal releases goes.

There is NO DolbyVision video playback software support for playback of DV UHD Bluray Rips on any LE hardware!

Even the very capable Apple TV 4K has no playback software support for such Rips.

You Will be wasting your money chasing such playback functionality.

Have you read the following thread that explains it all ?

Does dolby vision playback for movies work with Libre Elec on the Minix u9-h?

I do not know how many times I've posted this but it's definitely going to be the last time.

If users can stuff around with Install to Internal scripts, they can definitely follow simply instructions to copy the LE data partition into Internal eMMC storage. There is then no risk of bricking a box at all because a SD card or USB stick is still used for LE bootup.

In fact you can use any old SD card or stick you have lying around then and still have a snappy day to day LE device.

[HOWTO] Boot from SD card, use internal memory for data

My setup is minix U9 -> HDMI -> yamaha audio receiver HTR-2071 -> TV.

No sound when playing video files after enabling audio passthrough.

Can anyone help me how to fix this?

Let me guess, you are using LE 8.9.6 ?

Audio with the new AML Linux Kernel is problematic. No sound is a known problem.

Simply STOP using buggy Alpha Software and use the stable LE 8.2.x.x Kodi Krypton.

Play Video - On Screen Display - Video Settings - play around with Deinterlace method.

Deinterlace method will only display when Software decoding.

Video playback - Official Kodi Wiki

Quote from netaccs

Hm... Even than don't know how.

Would be a good idea to post this like question, idea, some kind of request ?

It would be a good idea to read the Kodi Wiki that already has all this sort of info you are requesting.

Such as Video Calibration:

Settings/System/Display - Official Kodi Wiki

There is no such thing a LE subtitles. It's pretty much standard Linux Kodi Krypton that LE AML devices are running modified for AML audio and video playback. Kodi and different Skins handle subtitles.

Quote from Marciano

GDPR-1 i know you discontinued your builds but i only want to ask if deinterlace for ROCK64 with live tv (sd channels) will be fixed in official LE alpha?

I asked that same question about Rockchip recently to Kwiboo ...

Quote

..there is no current support for deinterlacing on rockchip, there is post-process support for deinterlace in the VPU IP that handles up to 1080p video. The issue is that we have no post-process support in (rk)mpp library, it is only implemented in the android version to my knowledge

However you can software decode 480/576i mpeg2 content and then use the YADIF2x Software deinterlacer last time I tried with the RK3399 ODROID N1.

HDR appears to not be working either...unless GDPR-1 knows something different ?

Quote from ersenos

everything is working pretty good, bit annoyed it doesnt ruin the 200mbps jelly fish very smooth as i read reviews it did

Bluray official Specs list 128Mbps as the max bitrate for 4K HDR - so basically no one cares if a 200Mbps test clip does not run smoothly.

I've not seen a test 4K HDR REMUX that included lossless HD audio exceed ~ 75Mbps and that was all smooth.

Is Kodi Refresh switching set to Start/Stop ?

Are you connected to a TV's HDMI 2.0 port ?

Just tested the U9 with LE 8.2.2.3 and Bluetooth and it is definitely working after I enabled it in LE Settings > Services

PS. If you use the word "test clip" you can get away with testing and troubleshooting anything and not upset "Chewbacca" !

Mentioning downloading - a No No.

The Shield has no auto colorspace switching for SDR / HDR and broken 10bit depth outputs after refresh switching when viewing 4K HDR content, plus it's 1080p > 4K picture upscaling is terrible vs an Apple TV 4K or what you would get from a modern 4K TV.

It has a way to go before being considered a serious, set and forget Kodi 4K HDR movie player platform for demanding users.

It does have Atmos passthrough audio tho.

Apple TV does pretty much everything but Atmos & DTS:X Audio passthrough. You cannot install a stable Kodi Krypton. The MrMC App has to be used which means no extra Kodi Skins or Addons can be installed over what is already included. Great powerful hardware the ATV 4K.

thanks for feedback, i went ahead and used the other method of Boot off USB and put kodi on internal and it worked great, feels much quicker now

[HOWTO] Boot from SD card, use internal memory for data

Glad someone has "seen the light"

Heck I think one of my old LE S9xx devices still uses an old 2GB Class 4 microSDHC card, but once booted up and using LE Kodi data from internal eMMC storage, it's a pretty snappy setup.

LE Kodi Krypton does not need huge amounts of internal storage space anyway unless you have a massive video library.

Quote from BeneDicT

In my opinion, and I suspect it will be an unpopular one around here, as it currently stands a second hand Apple TV is the best 1080/4K streaming device for services like Netflix, Stan etc. It's hands down the most widely supported. Roku is second best if your looking lower in a budget.

Not unpopular at all. I'm a big fan of Apple TV's 4/4K running tvOS 11.x that gives you nice smooth video playback in all sorts of Apps. Better than any external Android media player.

They are great devices for Netflix, Amazon Video,1080p YouTube etc.

Hell if you do not need all the Addon's/Skins bells and whistles and Atmos / DTS:X audio from a full blown version of Kodi Krypton, the MrMC or Infuse Apps do the job well playing back content over a local home network. HD Audio output comes in the form of lossless LPCM, for no loss in audio quality.

Firmware support from Apple is excellent too.
