[libva error]

I tried to make possible to use hardware decoding on my Beelink tvbox with Armbian-20.10 with Ubuntu Bionic version (with kernel 5.9.0) compiled by @balbes150 but this error message occur:

root@arm-64:~# vainfo 
libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns -1
libva info: User requested driver 'vdpau'
libva info: Trying to open /usr/lib/aarch64-linux-gnu/dri/vdpau_drv_video.so
libva info: Found init function __vaDriverInit_1_0
Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory
libva error: /usr/lib/aarch64-linux-gnu/dri/vdpau_drv_video.so init failed
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

I read a topic Understanding Hardware-Accelerated Video Decoding b

ut I still can't understand:

 

1. Why libva need VDPAU backend libvdpau_nvidia.so because my Beelink box has Mali-450 GPU?

 

2. How it's possible to get libvdpau_nvidia.so file? On Ubuntu bionic this file available in packages only for architectures: [amd64] [armhf] [i386] but not for aarch64 (ARM architecture of my Beelink).

 

3. Maybe need to use exactly some value for LIBVA_DRIVER_NAME environment variable?

Thanks! Via apt-cache search ... apt-get install. If I will use System -> Other -> Switch to other Kernel is it possible to get kernel source also?

[Kernel source packages for native compile on x96mini Amlogic S905w tvbox]

Where is possible to get archive kernel-sources for Armbian to compile kernel on  x96mini Amlogic S905w tvbox?

Thank you, Werner!

[Amlogic S905w TV box - recompile kernel]

Recenly I successfully installed Armbian_20.10_Arm-64_bionic_current_5.9.0.img.xz created by balbes150 (may thanks to him) on microSD in my x96 mini Amlogic S905w tvbox. I need to enable option CONFIG_BINFMT_MISC in kernel

#  uname -a
Linux arm-64 5.9.0-arm-64 #20.10 SMP PREEMPT Wed Oct 14 12:04:42 MSK 2020 aarch64 aarch64 aarch64 GNU/Linux

When I tried steps from this link

on my Ubuntu Focal 20.04 x64  build environment I see only these possible variants according to Amlogic SoC:

- lepotato Amlogic S905x quad core 2Gb RAM SoC eMMC;

- lafrite Amlogic S805x quad core 1Gb RAM SoC eMMC;

- nanopik2-s905          Amlogic S905 K2 quad core 2GB RAM SoC WiFi eMMC;

- odroidc2               Amlogic S905 C2 quad core 2GB RAM SoC GBE;

- odroidc4               Amlogic S905X3 quad core 4GB RAM SoC eMMC GBE USB3 SPI;

- odroidhc4              Amlogic S905X3 quad core 4GB RAM SoC GBE USB3 SPI 2 x SATA;

- odroidn2               Amlogic S922X hexa core 2GB/4GB RAM SoC 1.8-2.4Ghz eMMC GBE USB3 SPI RTC.

 

So actually I'm not sure if I need to use a mentioned tutorial with running $ sudo ./compile.sh

Maybe exists another proper way to recompile my current kernel on tvbox?
