Still, RDP and VNC are not secure enough to open a port directly to Internet.

I rather suggest x2go, which is much more secure (works over ssh), and also a lot faster. Plus, it allows forwarding of sound, local folders and printers.

Although the battery connector allows to keep the RTC running while board is powered off, there is no PMIC to control power of the board from some kind of WakeUp Alarm.

THE MEDIA SCRIPT IS DEPRECATED, IN FAVOR OF THE LEGACY MULTIMEDIA INTEGRATION. PLEASE REFER TO THIS TOPIC:
 
So finally we have the first version of:
The UN-official, UN-supported, etc...
RK3399 MEDIA TESTING SCRIPT
 
This is the first release of the RK3399 media testing script. The script provides a functionality similar to its RK3288 equivalent:
Installing all the libraries and system configurations necessary for GPU accelerated X desktop, Chromium WebGL, full VPU video play acceleration up to 4k@60 10-bit HEVC (the maximum supported by the SoC), and GLES 3.2 / OpenCL 1.2 support. Three video players supporting full VPU acceleration (RKMPP) and KMS display (GBM or a X11 DRM "hack", as described by the authors), namely: MPV, Gstreamer and Kodi. Two example programs using the OpenCL functionality: Examples form the Arm Compute Library, and a GPU crypto miner (an old version, but small and simple). A library that will act as an OpenGL to OpenGL-ES wrapper, allowing you to run programs that use OpenGL 1.5-2.0. Two additional features, that have no big interest from the Armbian development prospective, but I find them interesting to play with:  Chromium browser with support for Flash and DRM-protected commercial web video streaming (tested with Amazon Prime, should also work with Netflix, Hulu, etc.), and a simple Pulseaudio GTK equalizer using LADSPA.  
Here is a more thorough documentation:

Prerequisites:
You need a fresh Armbian Bionic desktop image with legacy kernel installed.  
Instructions:
Download the file above Untar it: tar xvf media-rk3399_*.txz cd media-script ./media-rk3399.sh  
Notes:
This script is not officially supported by the Armbian project. It is just a community effort to help the development of the main build, by experimenting with a possible implementation of the media capabilities of this particular SoC. Therefore, questions about the script should not be laid out as support requests, but as commentaries or community peer-to-peer assistance. That being said, all commentaries/suggestions/corrections are very welcome. In the same way, I will do my best to help solve any difficulty that may arise regarding the script.  
Enjoy!

No, I mean for the future. When focal is released, still leave Bionic for rockchip legacy desktop as an available download in the main page. Only for legacy desktop, not current

Here is an update about multimedia integration: I have been trying to make all the Rockchip-legacy stuff work on Buster, and I am not able to get accelerated X desktop. I cannot find the exact cause, apparently something is making eglInitailize() fail. My guess is it has something to do with mesa libs, but could not debug the exact cause.
 
In Rockchip, they are working in a completely new approach, using exa instead of glamor acceleration. They need to use for that another particular feature of their SoC's, called Rockchip-rga, which in turn needs its special kernel driver and userspace libs (similar to their rk-mpp). So far, it does not seem to be working in the 'stable-4.4-rk3288-linux' branch we are using, and the stable-v2 branch does not compile ATM. I wasn't even able to make it work with their own linaro image.
 
So my proposal is that we keep the download option of Bionic Legacy Desktop for all the rockchips, with the link to the media-script thread, for those who need to use some of the features that are still only available in legacy kernels. ( @Igor would it be possible to keep it for a while? Bionic still has three years of support ).
 
With newer releases (Buster, Focal), we will focus on mainline, and hopefully at some point legacy won't be necessary at all.
 

Yes, it is a known issue with glamor, that instead of "accelerating" it slows down certain 2D operations. In the case of Rockchip's modified glamor to work with OpenGL-ES, It is even worse. It is the trade-off for having the possibility of an accelerated canvas for 3D, video playing, browser, etc.
 
However, in the mainline kernel and current X server, they are tweaking glamor to be much more efficient. Hopefully we can see a stable version soon.

The media script is only functional with the rockchip 4.4 kernel.  The upstream decoder support is incomplete, and incompatible with the Rockchip driver.

Well, they have backported mesa to bionic-updates, up until 19.2 so far. So it is very likely that in the near future they will backport 19.3 too.
 
Maintaining our own package for mesa 19.3 would be a source for trouble, IMO.
I propose to disable glamor in /etc/X11/xorg.conf.d/01-armbian-defaults.conf, by adding something like this:
Section "Device" Identifier "Default Device" Driver "modesetting" Option "AccelMethod" "none" ### "glamor" to enable 3D acceleration, "none" to disable. EndSection This will do the trick for the time being, and will make it very easy to enable acceleration when the necessary libs are available.

I'll try to make it for Jan 25 with the integration of multimedia support into the build script

Run for your life...!!!

Hi Igor,
 
it would be an honour to help you on your project. I highly respect this forum and I'm really interested in ARM Technologies and Debian based distributions. My hat's off to the guys at Armbian to manage a huge project like this
Besides that I'm using SBCs for server solutions another attempt to get a deeper look into ARM technology was to deal with Banana Pi products on Amazon. This attempt cost me a lot of time and in the end I almost lost my company too. The product line of SinoVoip or Bipai Keji (HK) Limited got messier each month. After they fired my main supporter anything got worse. Since then I'm seeking for a new opportunity for my company to get a footstep into the ARM world. Especially the Armbian Forum.
 
I ceased the Amazon sales last week. Therefore I have a few hours left each week for a new project. So the time would be perfect to support an opensource project. If you're interested, I'd looking forward to get to know each other on the Armbian Forum.
What might interests you as well is that I worked as a first level supporter, almost for elder people, for 3 years. So I know my place if something gets out of control and people gets angry or confused.

The only problem I may see is if you need moderators with short reaction times or too much hours each day. I think I can handle work like once, maybe twice, a day for something around an hour or so - 12/5.

I'm looking forward to read you
Best Regards, _r9

As a result of all the work that Armbian developers put into the upgrade to kernel 4.14 for the XU4 board family, now we can enjoy many new features. One of them is the access to the SoC video encoding capabilities.
 
Emby Media Server can take advantage of the Exynos 5422 MFC video engine for transcoding. That means lower CPU usage, lower temperatures, and the possibility of encoding in real time higher resolutions or more simultaneous streams. In my tests, I've been able to transcode one HEVC 1080p and one 480p at the same time, or five 480p (though it will depend on the bitrate of the source material).
 
However, the ffmpeg version shipped with official Emby is quite unstable when using this feature. For that reason, I compiled a better and more stable version from @memeka's repo. I've been using it for over a month without a single crash.
 
So this is a step-by step guide on how to make everything work:
 
0. [PREREQUISITE]: You must be running an Armbian Strech XU4 "Next" image, like the one you can download here.
 
>> DOWNLOAD the emby and ffmpeg packages from this link << Install them (Note: this will install Emby Server version 3.5.3, which is the last at the writing of this tutorial. It has been tested to work with this version, and may or may not work with any other): $ tar xvf emby-server-stretch-xu4_1.0.tar.xz $ sudo dpkg -i ffmpeg/*.deb $ sudo dpkg -i emby-server/*.deb $ sudo apt -f install  
Hold the ffmpeg packages, so they don't get upgraded:  
$ sudo apt-mark hold ffmpeg-doc ffmpeg libavcodec-dev libavcodec-extra libavdevice-dev libavfilter-dev libavfilter-extra libavformat-dev libavresample-dev libavutil-dev libmysofa-dev libmysofa-utils libmysofa0 libpostproc-dev libswresample-dev libswscale-dev  
Add the user "emby" to the video group, so it can have access to the transcoding engine: $ sudo usermod -aG video emby  
Modify the emby executable, to use our custom ffmpeg (Note: you will need to repeat this step every time you update the emby deb package): $ sudo nano /opt/emby-server/bin/emby-server # Change the following line: ffmpeg $APP_DIR/bin/ffmpeg \ # to: ffmpeg /usr/bin/ffmpeg \  
Restart the service:
$ sudo service emby-server restart  
Now, you can open the web browser, point to your Emby server (e.g. http://odroidxu4.local:8096), and configure it as described in the official tutorial (https://github.com/MediaBrowser/Wiki/wiki/Installation).
For last, you need to enable Hardware video transcoding in the web interface. The option is under the "Transcoding" submenu. Don't forget to click on "Save" when you are done:
 
 

 
And that's it!
 
As an additional tip, I recommend disabling UPnP in Emby, because it causes the program to crash frequently when enabled (this is just a general recommendation, it has nothing to do with hardware encoding).
 
Enjoy! And please, share your experiences and comments here.

The ffmpeg provided in the thread above should work, if you are using Debian Stretch. Please follow these steps:
Install the ffmpeg packages, and hold them to avoid upgrades, as described in the thread above Make sure your user is part of the "video" group: sudo usermod -aG video <yourusername>  
Then reboot, and try the following command line: ffmpeg -i <infile> -an -vcodec h264_v4l2m2m -b:v 2M -pix_fmt nv21 <outfile>.mp4  
Post here the results. 

The UN-official, UN-supported, UN-timely, UN-derrated...
Exynos 5422 MEDIA TESTING SCRIPT
 
Yes, the script is somewhat untimely, because it comes when including kernel 4.14 in Armbian next images is getting troublesome. And underrated, because this old SoC seems to be losing the focus of attention in favor of some more modern powerful ones. But it is still a great SoC, and it is worth trying to get the best out of it.
 
The script will provide the installation of all the libraries and system configurations necessary for GPU accelerated X desktop, Chromium WebGL,VPU decoding/encoding acceleration through MFC, and GLES 3.1 / OpenCL 1.1 support.
It will also install two media players (MPV and Kodi stable) and FFmpeg, all of them using VPU acceleration.
Two example programs using the OpenCL functionality: Examples form the Arm Compute Library, and a GPU crypto miner (an old version, but small and simple).
Two additional small packages, that have no big interest from the developer prospective, but I find them interesting to play with: Support libraries for commercial web video streaming (tested with Netflix), and a simple Pulseaudio GTK equalizer using LADSPA.
 
Since all the features require the 4.14 kernel to work, the script will also give the option to install an archived 4.14.43 Armbian kernel, in case some other version is detected in the system. Of course, the best option is to use armbian-config to perform a kernel upgrade, but we are providing the archived version just in case the 4.14 packages disappear temporarily from Armbian repos.
 
Also, this script can be tailored for desktop or headless installation, by selecting the appropriate options in the main menu.

It should run as your regular user. Can you launch the browser from console (as your regular user), and post here the output?

You're right, now I remembered there are some arm64 SoC's that don't have crypto extensions because the manufacturer didn't pay the license. For example, Amlogic S905 (though S905X has the extensions). So we can also discard Odroid C2 and Nanopi K2.

Wow, the discount is huge. Though, since shipping and toll fees will be much more than the board itself, you need to order several units to make it worth.
 
Good choice!

Let's see if I get a chance to look at it. Thanks!

Maybe it's time to try creating a set with HW acceleration of full screen video playback based on the new kernel 5 ?
All necessary components are already working (tested using LE images with kernel 5 for rk33xx and HW).

It should be working only for encoding, according to the ffmpeg output you provided. But, since it is doing SW decoding, therefore the high CPU usage. Just try this command line instead, for both HW decoding and encoding:
ffmpeg -vcodec h264_v4l2m2m -i <infile> -an -vcodec h264_v4l2m2m -b:v 2M -pix_fmt nv21 <outfile>.mp4 It should run steadily at a little less that 60fps, with minimal CPU usage.

Well, AFAIK hardware encoding is not yet supported with the FOSS Cedrus library, which is the only one you can use in mainline kernels. If you want HW encoding on Allwinner, you would need the old and controversial closed-source CedarX binaries for that. They only work with older 3.4/3.10 kernels. So the reason why your SoC is getting so hot is probably because it is using mere CPU power for software encoding.
 
If you want to do h.264 hardware encoding, your best options are rockchips (rk3288, rk3399 and rk3328, ordered by preference), or Odroid XU4/HC1. All of them can do HW encoding with Armbian, if you use my media packages.
 
Notice that rockchips will use gstreamer, while XU4 will use ffmpeg.

If you follow the link I posted above, you will see at the status matrix that, indeed, encoding is not yet implemented.
 
It has the most standard and easy to implement and use interface, v4l2-m2m
 
XU4, MC1 and HC1 are sold now for less than $50, which I consider cheap considering its power, features and stability. Take into consideration that one of these can do the work of four to six H3 boards, for example. And if you want to build a farm, you can stack several HC1 or MC1, and put a fan on them, which will make them run steadily at maximum frequency.
 
If you still want something cheaper with HW encoding, then you can go for a 1Gb Rock64, but these boards are having lots of stability problems lately.

Hello, I've the Rock64 4G v2.0 - 2017-0713. I tried to install different OS but I get similar errors and problems as yours. The SBC stuck after a while or lost the connection after high I/O traffic with my SSD on the USB3.
If It can help you, I describe here how I could installed a clean Armbian on my rock64:
- Download u-boot-flash-spi-rock64.img.xz from here and use Etcher to write to a new micro SD card; I used SanDisk Ultra 16GB microSDHC, Class 10. 
- Download OS image “Armbian 5.69 Ubuntu Bionic default, Kernel 4.4.167” from the archive here and use Etcher to write to the SSD.
- I both a new power supply because I get some under voltage errors. But I still have to measure the differences. I've got this by amazon. 
- Insert the SD card into Rock64 and boot it. It will automatically flash the SPI memory. Wait until the white LED on Rock64 blink once per second. Wait for some more time just to ensure the writing is done and then remove the SD card and power off the board.
- Connect network cable to Rock64 and attach the SSD to USB 3.0 port and then boot Rock64. Log in only with HDMI monitor and Keyboard and change the pw and user name. 
- Connect the SSD to another linux and check and repair the partition (job 1) and extend it till the end (job 2).
- Re-connect the SSD and go to armbian-config and then freeze the Kernel and File System. Check desmeg results. Try also to connect with ssh.
 
I get now a clean and stable board and I´m happy after many month trials. If I can help someone would be nice. Let me know.
