Dolby Digital works fine also with Atmos😊 the DTS works sometimes but When I activate TrueHD and DTS-HD I get just noises.

as jernej mentioned there is no support for HBR audio in the upstream HDMI driver (yet) and I'm slidly suprised that it works on android, since vendor kernel doesn't seem to have that implemented as well.

If your AVR support HBR audio via SPDIF, its worth a try to check if this works. (Note: Bitstream parsing is currently partly broken / unmaintainted on kodi side, which is propably the cause why DTS works only sometimes). There is also an part-fix for compressed audio pt which didn't make it into beta2 release - its available in current nightlies.

Please check latest realease / nightlies and my reply RE: LibreELEC (Matrix) 10.0 BETA1 the Remote-Control dos does not work

Please don't double post: see Rock Pi 4 and old Sony TV

You're obviously using old 9.2.x image. Please check 9.95.2 or latest nightlies.

Besides a different device tree there are more requirements to be able to support RK3318 which might get added some day. For now it remains unsupported - images won't boot.

zeus24  NVMe support for RK3399 is enabled in latest nightlies.

There are still some oddities with the upstream cec-driver, this however, seems to work for my TV (Samsung).

Note that takes up to 10 secs to "recover" the connection. Can you paste the output of cec-ctl -m somewhere when switching TV on/off? It should look something like this: http://ix.io/2ZFX

There should be no reason to disable HW decoding for MPEG2 on RK3328 - I never heared of or had any sample which wasn't decoded correctly.

This, however, doesn't mean that it doesn't exist

Could you share one or more samples (the more, the better) which don't work for you? It will help to track down the issue.

As I said I am newbie, with very little knowledge of Linux, I have tried and tried he tutorial, and I cannot make the remote work. I went back to version 9.2.6. which the remote works.

Yeah, you've said that before and I could have been a bit more verbose

I checked which keymap we had in LE9.2 for rock64 - it was pine64. So all you would have to do is to login to your box via ssh - and execute

echo "* * pine64.toml" > /storage/.config/rc_maps.cfg

re-check if content of that new file is OK with:

cat /storage/.config/rc_maps.cfg

which should give

* * pine64.toml

after that

reboot

After that your remote should be working again.

HansRJ : In mainline kernel RK3328 roc-cc doesn't have a preconfigured keymap defined, which makes sense, since the device isn't sold with a paticular remote - so you'll have to create a keymap your own following the tutorial at Infra-Red Remotes - LibreELEC.wiki. We also have a lot of preconfigured rc keymaps installed as kernel modules which you can find at ls /lib/modules/*/kernel/drivers/media/rc/*.

Other options to control the device is via USB/BT keyboard or CEC.

Edit: sorry: I mixed devices up: but the same is true for rock64.

XFS formatted hard drive works in the latest nightly built (nightly-20210311-3f55efc). Files can be copied using SMB as well as plays well.

Thanks for testing.

(1) Rock64 - not providing 1440p resolution for 32" monitor. (Actually all LE10-nightly)

Its a feature, not a bug.

I'm tryiing to stay as less technical as possible: RK3328's HDMI phy supports only a very limited number of (TMDS/Pixel)-clock rates. In previous (vendor kernel) versions they were alll supported within a given min-/max-range which is not correct and resulted in non-working screens for many people (and no possibility to easily change it). In mainline kernel we support only exact rates (+/- 5% which is the VESA standard) and 1440p respectivly 241.5 MHz TMDS-/pixel clock is not natively supported by RK3328's hdmi phy (even if might have worked for your particular screen). This might change if the vendor provides settings for more rates in upstream kernel. In short: stability beats compatibility here (again).

Note that the report is about vendor kernel stuff while we are now using mainline kernel. The (huge amount) of work of last months/years was to port vendor code to mainline kernel / ffmpeg and it is possible that some shortcommings were ported as well - I'm confident they will be ironed out with ongoing work.

The whole HEVC/HDR, VP9 and the 10 bit output are all WIP and is what makes this a beta release for Rockchip and should be seen as technical preview.

Thanks for reporting this - the issue seems related to this check: linux/drm_gem.c at master · torvalds/linux · GitHub and is not limited to Rockchip - it could be reproduced on Allwiner H6 also.

Now that panfrost devs are involved I'm pretty confident the issue (which seems really is only about this warning, since I couldn't see any issues with the actual output) it will be resolved soon.

Due to the lack of time of Kwiboo I added his latest work to LibreElec recently which also adds some functionality:

• H264 Hi10 decoding and rendering (RK3399 and RK3328)
• proper decoding of H264 field encoded content on all SoCs
• USB3 support for RK3328
• HDMI / DRM addtions to support 2160p@60Hz on all SoCs (RGB444 on RK3288/RK3399, YUV420 on RK3328)
• WIP patches to support VP9 and HEVC decoding on RK3328 and RK3399 (keep in mind: WIP!)

They are included in latest LE nightlies on Index of /

There are no updates in regards of HDMI passthrough and this won't change any time soon.

Also there are some shortcommings in some upstream devicetrees (no hdmi sound enabled for example for RK3288 miqi) which I will be addressing in a follow-up PR.

Note: Due to the lack of upstreamed devicetrees not all devices that were supported in LE 9.2 can be supported in future. (its very unlikely that LE will add support for devices that do not have a devicetree in mainline kernel since it will add additional overhead with rebasing and adapting this with every kernel update). So: If you want to your device to be supported: You'll have to go the "extra mile" and submit it to mainline kernel (or at least suggest it there and hope somebody else is doing the work for you)

Also: please don't use update functionality for LE 9.2 -> LE 9.8 and use an extra SD card for this tests.

There were some updates pushed recently to LE master recently which consits of serveral functional additions for RK3399:

- up to 4K@60Hz HDMI

- Hi10p (H264 10bit) decoding

- HEVC/VP9 decoding (WIP!: There are still some HW related issues especially on RK3399 and also not all streams/videos are decoded correctly)

See Rockchip update by knaerzche · Pull Request #4988 · LibreELEC/LibreELEC.tv · GitHub for details.

So: feel free and test latest nightlies on Index of / and share your impressions

Any instructions how to extract device tree from Android? I'

The easiest way is probaly with adb: so connect your device via usb or network to your working machine and do:

adb pull /sys/firmware/devicetree/. backup

this should copy all the files an directories in there to your PC.

after that you can decompile to a readable devicetree with:

dtc -I fs -O dts backup/base

Note: I wrote this from my memories ... might be that syntax is slightly different.

EDIT4: Temp is 208ºF (98ºC) when playing videos, is that reading correct? Holy crap!

unfortunately: yes.

-Is a new release on the horizon? Latest is from April 2020 and I saw many commits on github, including Kodi 18.8.

Maybe yes - honestly in my little spare time I'm trying to port more and more needed stuff to mainline kernel which I'm far more interessted in ... but I can do some builds ... in the meantime everbody else can build his on images which is really, really easy: You need just a linux computer (preferably with ubuntu 18.04 for LE 9.2), follow instrucations on Compile [LibreELEC.wiki], clone my repo and execute any command from LibreELEC.tv/README.md at libreelec-9.2 · knaerzche/LibreELEC.tv · GitHub which suits your device.

Hi!

Any chances for LE9.2.3 with Kodi 18.7.1?....

Yeah, I know I'm late I will add some new builds this week. Everthing RK322x releated is already merged in my repo ... you could build yourself if you like
