S905(x) ALPHA media capabilities testing script



Well, no fancy introduction here, because this doesn't pretend to be a script for the general use, only for testers who want to try the current *very early* status of the media capabilities in the Armbian meson mainline kernel.


Warning: It will replace your current kernel with a pre-compiled nightly 4.19.20.



Download, untar and run. If you need further instructions, then you are not ready for this script (again, it is very unpolished, not for general use).

Things that you can try with this script, on a X session:


  • Use a 1080p@30fps h264 video, and play it with "mpv -hwdec <filename>". You'll see in the logs that it is decoding through v4l-m2mcopy
  • Install and run glmark2-es2
  • Use Chromium WebGL
  • Play a 1080p@30fps video in YouTube in full-screen smoothly. I'm pretty sure it is not really using HW decoding as it claims (there is no  initialization message in dmesg), but it's smooth for sure.


Gstreamer is tested not to work, in some other forum I was told that Bionic version is not enough and I need to compile a newer one.


Performance is not in any way good, but it is a starting point. Anyway, the first TO-DO is getting the mali module integrated into the kernel, so there is no need to compile it separately.

I propose to make a change to the script. Build the MALI module itself directly on the production system with the current kernel. Check for kernel headers, if available, install the sources for MALI and run the build of the MALI module on the current system.

Well, actually I tried to build it natively against the kernel headers, and it didn't work. I had to cross-compile it against the original kernel build tree. I must recognize that I didn't try too hard the first option, though.


However, what we really need is a way to integrate it into the main kernel build which, for some reason, seems to be harder than with other mali flavors. We are having the discussion about the subject on this other thread.

Found a small error in the script. No links to the installed libMali file are created (not copied) during the installation process. In the system at this point is the same files from the shared installation. If manual overwrite these files with links to liBmali, begins to work MPV full screen. Gstreamer I have not yet been able to run, it gives an error, I need to see what can be fixed. I tried the usual Chromium from (not 32 bit) the after fixing the libraries, now the video from YouTube works at full screen with almost no brakes at the desktop resolution 1080 and if you choose a video with the parameter 1080. When displaying video in the browser window, noticeable braking and artifacts.

Here is the log file, running on khadas vim, armbian 5.75., kernel 4.20.5.


Maybe i am missing some packages?



To anyone who has problems with installation, use Midnight commander, it works with it!

It looks like you weren't running the install script from the script's folder, but from some other directory. You must untar the tarball, cd into the created "media-script" directory, and run "./media-s905.sh"
