I come back with some bad news unfortunatly.

Video playback in youtube as ElBoluTony say work fine, like youtube.

The reason why we can"t play 1080p (and 720p, it's not pleasant...) is because the Netflix addons and the Amazon prime video extension use the CPU to "decrypt" windevine DRM protected content.

Our rock64 has only L3 Windevine, while we need L1. So that L1 is "emulated" and use a lot of CPU ressources, because the GPU is in this case : totally useless , that's why the playback is not good, Rock64 is not powerfull enough...

Don't know what we can do more, i love that device, but seriously i start to hate it, we can do nothing on it... Android TV, you can dream to use netflix or amazon prime video app, even if it was, it will be SD video playing because of L1 DRM

Unfortunatly on lLibrelec, we have a chance but the L1 emulation use too much power, don't know if it fixable

I already posted several LibreELEC builds for MVR9, Rock64, ROC CC with 720p Netflix software decoding support.

But seems no one even uses it. Search for it in the forums.

Devices like the RockPi 4 RK3399 can even decode 1080p Netflix in LibreELEC with my image.

Hi

Please test this image for the added audio jack code.

Hello I have a rockpi4b sbc with libreelec LibreELEC-RK3399.arm-9.1.501-rock-pi-4.img.gz installed. I have problems enabling audio out from the analog 3.5" jack directly from libreelec. I get only audio from HDMI or if I plug a USB dac.

I have tried HDMI, analog and ES8316 analog and nothing seems to work.

if I run allay -lL I get the options indicated in the attached pictures. Please advise to enable analog out.

Regards

Hi

I fixed the audio jack problem.

You will have to wait until I build a new image in a day or 2, then you can test if it works.

Everyone getting crackling audio

Please post LibreELEC debug logs if you can, then it can help Rockchip to look into the issue faster and determine the cause.

What happens if using interactive governor?

Have you tried setting the refresh rate switch form 'On start/stop' to 'On start' only in the Display Settings?

Rockchip devices doesn't work the same as Amlogic.

You have to write a new ir remote driver for the kernel if your remote doesn't work.

I have problem with playing video with resolution 960x540 qHD with hevc, playing only sound. Other videos no problem.

I have installed release LibreELEC-RK3328.arm-9.1.501-rock64.img.gz

What could I set?

Can you post some sample videos?

It would be interesting to test it on different Rockchip devices.

I build a new image for RockPi 4 if anyone is interested.

Does not work on mainline linux

It's for Amlogic devices running Android Kodi or CoreELEC so won't work on Rockchip devices.

I already tested it on an Amlogic device and it worked, shows a lot of useful video and display info.

But I hope someone will be able to modify the addon to get Rockchip video parameters so it can be displayed when you press 'o', would be very interesting.

I see some new patches for H.264 decoding : LKML: Ezequiel Garcia: [PATCH v5 00/11] media: hantro: Add support for H264 decoding

Is it good for us if this land mainline ?

Yes, since Linux OS's like LibreELEC, Armbian, Manjaro etc. will then also have out of the box video playback capabilities if using the latest mainline kernel without any tweaking, special drivers or old kernels that need to be used.

Only H265, VP9 I think must still be added since mpeg2, mpeg4, H264, VP8, HDR, HDMI CEC I think are already far developed for the mainline kernel.

The open-source Mal GPU Panfrost, Bitfrost drivers landing in the mainline kernel will also help a lot for the graphics acceleration to have a complete Linux experience.

Quote from phv0v

Can anyone help me???

No, it doesn't have any Linux support.

You need a RK3328, RK3399 or RK3288 device.

Quote from buximze

thanks mo123 , another question, i have a rock64, but i'm inclined to buy a rock64pro just to get the pci express dual sata card to connect 2 Hard disks.

the question is does libreelec have drivers to support this card? so i can build a libreelec with 2 hard disks connected to the system?

Best regards.

You might need to add the drivers or make dts changes to the LE kernel and build your own image to support that or ask Pine64 if it works.

Quote from buximze

does the rock64/rock64pro can output them correctly in HDR? did anyone made the tests?

Best Regards.

With the mainline HDR support Kwiboo is working on and the driver only recently being created by Intel, it should be possible later.

Hello colleagues,

i'm trying to load the LibreElec firmware onto my VS_RK3399, but the upgrade_tool uf LibreELEC-RK3399.arm-9.1.002-sapphire.img command fails:

Code

1. ./upgrade_tool uf LibreELEC-RK3399.arm-9.1.002-sapphire.img

The output is:

Code

1. Program Data in /root/.config/upgrade_tool
2. Loading firmware...
3. Loading firmware failed!

And that's it.

The board is in recovery mode and is also recognized by the upgrade_tool:

Code

1. [email protected]:/opt/dev_boards/rk3399/linux/rkbin/tools# ./upgrade_tool LD
2. Program Data in /root/.config/upgrade_tool
3. List of rockusb connected(1)

Any ideas?

Many thanks!

How do you want to use an Android flash tool to write LibreELEC to EMMC?

You write LibreELEC with etcher to a micro-sd card.

I'm not aware of any compatible LibreELEC image for VS-RK3399.

Someone can perhaps build an addon like this but for Rockchip devices?

GitHub - roidy/script.amlogic.colorformat: Amlogic color format information script.

It can be very useful to test display mode, color depth, color space, color range etc.

Quote from Ant123

Hi, guys. First of all, let me congratulate everyone for making amazing progress on making LibreELEC work as perfect as possible on Rockchip devices.

I thought I'd give feedback regarding my overall experience after testing various current images for RK3328 devices and hopefully this feedback will help improve any future releases.

First off, I am running an R10 RK3328 Android TV Box.

Second, my preferred LibreELEC build is the latest MVR9 image (LibreELEC 9.2 Alpha) which you can download right from this site: Rockchip – LibreELEC

I have tested all the LibreELEC 9.2 Alpha images for RK3328 devices. They all boot into LibreELEC but MVR9 image works best for me because I get Internet connection via Wi-Fi (wired connection doesn't work) and I get sound from my speakers via AV port by selecting the I2S analogue sound option in Kodi settings.

Regarding other LibreELEC 9.2 Alpha versions I tested, some of them don't have Internet at all / others have Internet via Ethernet but no Wi-Fi, but those images don't have the I2S analogue sound option so I get no sound to my speakers.

Okay, that would be my feedback regarding sound and Internet.

Now, to the second part, which is video playback.

Again, LibreELEC 9.2 Alpha MVR9 image works best for me. There are only two small problems: a) colors in 4K videos seem to be a bit washed up. That's especially apparent if I bring up navigation bar during playback. Then the colors become even more pale

b) MPEG-4 files are extremely choppy as LibreELEC 9.2 Alpha doesn't yet use HW acceleration for those files, so I guess that's where the problem lies.

The two latest developmental images I've tested have other bugs, but they fix these two video playback problems for me.

First off, regarding washed up colors in 4K videos, the latest MVR9 LibreELEC version on this link (LibreELEC-RK3328.arm-9.80-nightly-20190719-235fdbc-box-trn9.img.gz) has better colors, but here videos get a bit choppy when bringing up the navigation bar.

And secondly, regarding choppy MPEG-4 videos, the latest image by Kwiboo (LibreELEC-RK3328.arm-9.1-devel-20190512173254-bdfaff1-box-trn9.img.gz) fixes that problem, but the playback of other video formats has gotten worse and very, very buggy.

So, if you could somehow merge the official RK3328 MVR9 image with the good points from these two other images, it would improve things a lot.

I guess my recommended list of fixes would be:

1) HW acceleration for MPEG-4 files

2) improved 4K video colors

3) Ethernet connection available on MVR9 image.

Thank you for reading.

Gigabit ethernet is broken for all RK3328 devices at the moment., Kwiboo said he will look into it.

It is working on the old 4.4 kernel images that are now discontinued.

By running the MVR9 images on your device, you must make sure your device also uses DDR4 RAM otherwise in the long run it will cause wear & tear on your RAM chips and can also cause stuttering video playback if used on a DDR3 device.

Kwiboo , we really need new images for testing, please

Hi all,

I am new to LE OS and I want to install it on a chinese tv box, Beelink A1 model

Specs for the box are:

Processor: RK3328

CPU type: Quad Core ARM Cortex-A53

GPU: Mali-450MP2

RAM: 4G RAM DDR3

ROM: 16G

I don't know what version of LE to download. The versions I found are:

Early mainline images for RK3288, RK3328 and RK3399

Rockchip – LibreELEC (Generic Rockchip Box - LibreELEC-RK3328.arm-9.1.001-box.img.gz)

Are there any stable releases for this type of android box/CPU?
What version of LE should I install?

Thank you!

Display More

No support for that Beelink device.

But you can try all the images, maybe one will boot but wifi, bluetooth and ethernet will most likely not work.

The device was also discontinued by them 3 months after release, so you also won't get any Android updates.

TICTID, MVR9, ROC CC, Rock64 RK3328 are the only ones with mainline LE support.

Quote from Trillian59

Hi Folks!

I just bought me some Rock Pi 4s to replace the old Raspberries here running Librelec.

So far, it looks good, even 4k films can be played (sometimes )

But I have noticed that Audio Passthrough to an external Amp really does not work with the Rock

Only static noise comes out of the Speakers (I've learned it the hard way last night, very late already.... bad karma...)

The Amp does not recognise any Dolby Digital or DTS Frames, instead it keeps on playing PCM, which explains the evil noise fairly well.

I found this thread, read it and hoped, there will be a solution, at least somebody is working on it right now.

But, I cannot make head or tails out of it, one says "yes", others say "no", one points to the "nightly" or "development" image (I've tried it right now, still no go )

So, at the end I feel quite lost.

a) is this problem known ?

b) does somebody work on it already?

c) if the answers are "no" what is the best place to report it???

You have to wait until mainline Linux support is added for Rockchip devices.

4.4 kernel images don't support audio passthrough.
