So far, So good! Only problem is major frame skips on some media. Can't pinpoint the exact type but it looks like it's only on some 720p types. I'll do some more testing and see if i can isolate the specific type.

ps. If I disable "Adjust display refresh rate" and playback at 60hz, then the problem is gone.

... And the audio is also off by 0.125s

Done some testing, and the only problem i can see is that the famous frame skip is back for some media.

Also tested setting dc_cap to 444,12bit , and my AVR reports YCbCr444 36Bit and all 8/10 bit looks OK. Haven't tested any 12bit yet, so don't know if it works

Thank you, it looks good. I've decided to hold off on future builds until I get the full nougat amports and 20170515 merges working correctly (nougat-exp kernel branch), which means there's a bit of work ahead. For now, testing1 seems to be in a very good state.

Agree, testing1 works like a charm for me, and I'm very pleased with all your work. A BIG THANKS to you and kazaq, and every one else who contributed to this build.

Quote from johngalt

To double check this isn't a different issue, could you run the following and post the output here? It doesn't matter which release you run the command on (so it's fine if you're back on testing1) cat /sys/class/amhdmitx/amhdmitx0/dc_cap

NexBoxTK:~ # cat /sys/class/amhdmitx/amhdmitx0/dc_cap

420,10bit

420,8bit

444,10bit

444,8bit

422,10bit

422,8bit

rgb,10bit

rgb,8bit

Thank you, I believe I found the issue from the merge again. I removed the build until I can fix it and verify. Unfortunately I didn't test >=50hz. For now I recommend testing1.

ps. Not sure if my TV supports 44410bit 50/60hz at 4K, but i know it supports 422 10 & 12 bits at 50/60hz.

I created an sdcard with 8.0.2a for my Tronsmart Vega S95 Meta - S905 2G/8G 1Gb eth.

Everything seems to be working very well. So I installed to internal.

Then I realised that I had not used/placed a device tree file on the card

Everything seems to be working great from internal - no stuttering/problems etc.

However I am unclear as to the device tree my installation is actually using and whether I should reinstall 8.0.2a with the "correct" device tree (gxbb_p200_2G_1Gbit.dtb).

Any thoughts?

I would say; If it works, It works... If it bothers you, do a new install

No 4k 10 bit video output also with latest release, Error on screen: no video input.

I tried three hdmi clables

8 bit 4k video output is ok

My AVR reports;

-YCbCr420 24bit for 4K >= 50hz. (8 bit)

-YCbCr444 30bit for anything else. (10 bit)

That's probably it. My TV's internal player does not exhibit banding though. Is dithering supposed to be turned on?

I'll just post the clip again.
hdr_banding.mkv

To all the people with an HDR capable set:

Play this file and please report back whether or not you can see banding artifacts within the white gradient.

The answer to your question is: Not!

Looks better on my box.

And even better with: echo '444,10bit' > /sys/class/amhdmitx/amhdmitx0/attr

I've taken kszaq's branch and cherrypicked in 3 commits:

Code

koen@libreelec:~/LibreELEC.tv-8.0$ git cherry -v | tail -3
+ 50fc937b8d863c9e50fe73fcd3aef2d49a0fcc7a S905: update audio config and patches
+ 44eebb8c7a27a3d2a23299315823582589e33893 S905: use custom test kernel
+ a1031f5ec821245cd2f1edc207cd31fc62643f3f S905: bump kernel

Most HDR videos play fine, but the Planet Earth II is given me problems, the colours are weird and the picture is full of artefacts. Below is a photo of the TV with the AVR overlay on the bottom and TV overlay on the top.

One of the differences between the working movies and this is that the working ones are 24/1.001 fps and this one is 25, so no change is needed from the 50Hz GUI.

For testing you can use this sample.

Looks better on my box.

Try connecting to the box with SSH terminal and execute the following commands:

fw_setenv hdmimode 1080p60hz

fw_setenv outputmode 1080p60hz

echo 1080p60hz444 > /sys/class/display/mode

Hi kszaq,
there are my quick tests:
Audio stereo files:
41.1 kHz - OK
48 kHz - OK
96 kHz - OK
192 kHz - OK
All tests are correctly mapped to 2 channels
5.1 Multi channel audio - OK and correctly mapped to 5.1 channels

Video with HD audio Passthrough:
Dolby digital Plus - OK
DTS HDMA - OK
DD THD - OK
Dolby Atmos - I cannot test it.
It seems, all audio are OK - Thanks you!!!

There are still problems with high bitrate BD rips with 30 (60) fps - jerky playback.
24 fps videos are OK.

Thank you very much!

Can confirm this, and Atmos and DTS X is also working fine.
Some miner bug if you let a movie play to the end. Hangs for 30-40 sec before ending.
Nice work!!!

No, not yet.
Do you have a suggestion for me? I never tinkered with these settings...
Which one would you tackle? remoterepeat?

Yes, and remotedelay. Just try with some larger values and see what happens.

Quote from jd17

I started testing kszaq's latest dev. build last night.
First impression is very positive.

- Chroma upsampling test pattern looked very good.
- Audio was perfectly in sync (regular AC3).
- 23.976 Hz was displayed properly.
- GUI seems very responsive.

So far so good.
I will continue testing within the next few days.

However, I am still facing issues with my external USB IR receiver.
Does anyone else experience that?
Sometimes pressing a button triggers a double action, sometimes an additional random action like play or left/right/up/down is triggered in the menus...

It is a cheap USB IR remote to emulate keyboard/mouse actions which works fine with the Raspberry Pi.

Have you tried changing the settings in advancedsettings.xml?

See section 2.10 in: advancedsettings.xml - Official Kodi Wiki

In Sistem/audio I enable passthrough like always (pic 1) but my rec recognize only dts (pic3)
Edit: something is not right in libreelec8. No matter witch audio type I passthrough (dd, dts, dtsma, ddthd) denon always see DD.
In libreelec 7 everithing working perfectly. Denon recognize all those types

Are you sure you don't have "Sync playback to display" Enabled?

Quote from Notna

Apart from 'define not working': I just tested 'Sing' with DTS-MA and that works perfectly fine using a Pioneer AVR 831. Did sync plaback to refreshrate turn on by mistake perhaps?

Question from my side; is there a way to edit the installed files for skins? I want to change the default background picture in the Aon Skin but I cannot seem to find the folder via Samba shares to edit the bg_background.jpg file? It was easy enough to find in Android but with LibreElec; no idea...

Connect with a SSH terminal, user:root pw:libreelec
folder: /storage/.kodi/addons/

Hello good ppl

Recently I updated libreelec to new 8.0.1.e version and I noticed that DTS-MA and DD-THD do not work.
In old libreelec 7 DTS-MA and DD-THD was working perfectly.
Is it just me or HD audio passtrhough realy do not work?

I have nexbox a95x (b7n) 2/16gb

Hi, Can you define "Not work!" ?

Quote from kszaq

Hey guys, having time off but still have Tapatalk. [emoji56]

Please observe if there are any audio issues in the dev build compared to 8.0.1e. I haven't posted any changelog but there is a fix for better fractional frame rates support and a change in audio handling.

Bitstream audio works fine, but with PCM my AVR reports Multichannel 7.1, but there is only 2ch front L/R.

PS. Sounds like Multichannels are downmixed to stereo.
