Hello,

 

I just intalled the new Armbian 5.10 on my orange pi mini. I tried to play a video, but after i start it there was only black screen and audio. If i changed the vo to X11 it's worked but with vdpau it's not. Can someone help me how to make it work?

 

Thanks,

Hello,

apparently you are logged in as root. you must create a Standard user.
You can try to connect via ssh: ssh root@ip. password: 1234
normally it should launch an account creation process.

You must replace ip by ip of our machine or by name.

 

On allwinner CPU only vdpau output is able to play video.

 

Your user must be in video group.

Hello,

 

I created an orangepi user. I also checked all files which need to play video and i have all in the video group.

 

But i still get black screen only

orangepi@orange:~$ id orangepi

Your user must be part of the group video normally is the case but it's worth checking.

This command will list the groups to which the user belongs : 

groups orangepi

you can post your kernel command line with:

cat /proc/cmdline

Hello,

 

orangepi is part of the video groups. The kernel commands is below.

orangepi@orange:~$ groups orangepi
orangepi : orangepi dialout sudo audio video plugdev netdev


orangepi@orange:~$ cat /proc/cmdline
console=tty1 root=/dev/mmcblk0p1 rootwait rootfstype=ext4 cgroup_enable=memory swapaccount=1 hdmi.audio=EDID:0 disp.screen0_output_mode=1920x1080p60 panic=10 consoleblank=0 enforcing=0 loglevel=1

Hi,

 

The results seem good. But you can test with 1920x1080p24 because video is rarely in 60 fps and blueray are in 24 or 25 fps.

 

You can test with mplayer which also support vdpau.

Hi,

 

You can change your screen resolution by the kernel command line.but it surprised me that the problem comes from this.

 

have you tested another video player?

Hello,

 

I just tested with mplayer2 and i think the problem is the codec, which cannot be loaded.

Do you have a ffmpeg version with vdpau support compiled in? And stay with mpv, mplayer2 is deprecated iirc.

I think yes

ffmpeg library versions:
   libavutil       55.17.103
   libavcodec      57.24.102
   libavformat     57.25.100
   libswscale      4.0.100
   libavfilter     6.31.100
   libswresample   2.0.101
ffmpeg version: n3.0

No, this is not the case. mplayer2 always show this h264 error. If you want it to work correctly, build mplayer from source. And i suggest you to to the same with mpv, ffmpeg and maybe libvdpau-sunxi. I can show you how i do it, even if it's a little noob way, but it works for me. But of course @rellla could be of more help here.

Hello,

 

@rellla:

I installed ffmpeg codecs and the result is the same,

 

@RagnerBG:

I think i'll install my whole system from the begining and use the non desktop version, so I'll know what's are installed and what's not.

 

If i stuck somewhere I'll ask help :).

What does ffmpeg -codecs and ffmpeg -decoders say? You have to compile it yourself, because ready built arm ffmpeg packages normally don't have vdpau support because of arm.

1, libvpau --> ffmpeg --> mpv

I am using this order, actually - libvpau --> some codecs --> ffmpeg --> mpv. But bear in mind that mpv have it's own build in ffmpeg, if you build it from source and i am not sure it using external ffmpeg at all. You can pass build options for it in ffmpeg_options file, in mpv-build directory. For example:

echo --enable-vdpau >> ffmpeg_options

Hi Sp0T,

check this out: http://linux-sunxi.org/User:Rellla/Armbian

 

It's necessary, that you don't install ffmpeg, libvdpau or mpv from the repositories (even not deb-multimedia.org) because the arm packages do not have vdpau support compiled in. You have to build them yourself. All packages should find the available dependencies themselves. But you can check config.log after you did ./configure what flags (espec. vdpau) are enabled.

Thanks rellla.

Just one more question. At this part:

  • "configure kernel with CMA enabled and sized to 192"

 

Do you must have to hardcode CMA into kernel or does "sunxi_ve_mem_reserve=192" is enough in the boot.src

 

Thanks,

Sp0T

If CONFIG_CMA is not set, you have to set sunxi_ve_mem_reserve. 150+ would be a good value. In Armbian default it is not set.

If CONFIG_CMA is set, sunxi_ve_mem_reserve= is ignored. By default, the CMA memory is hardcoded to 80MB.

 

So, if no patch activates CMA, you don't have to care about that, but just set sunxi_ve_mem_reserve. In this case, you also don't need libump and must not compile libcedrus with USE_UMP=1.

To let Mali and the VE use the same memory area for zerocopy features in the future (for the upcoming vdpau_gles_interop feature e.g.) you need to use UMP with CMA memory as backend. And then you have to increase the hardcoded 80MB depending on how much surfaces etc. your app uses.

 

I hope, this was kind of understandable ;)

 

Regards

I tried to get "https://github.com/rellla/lib/tree/ump " which not exist so i git cloned the "for_upstream brach from your github. Than i try to build a kernel for my Orange PI Mini A20 and the following error popped up:

[error] ERROR in function source [main.sh:113]
[error] Board configuration does not define valid kernel config

With orange pi A20 it's working.
