Accelerated H.264 and HEVC video decoding with Cedrus
#1
Starting with Kernel 3.10.65-2-pine64-longsleep-43 the media modules are included. This means one could use the hardware video engine on the SoC. So i felt why not try it - and surprisingly it worked Smile.

Pine64 decodes 1080p H.264 and HEVC just fine and smooth with Cedrus from linux-sunxi community.

You can do it yourself following the Cedrus build instructions on http://linux-sunxi.org/Cedrus

Pine64 SoC temperature is stable at around 70C while decoding HEVC 1080p (without a heat sink, no enclosure).

For easy mplayer launches with the correct parameters feel free to use https://github.com/longsleep/build-pine6...er-play.sh


I will not support this overly much, but it confirms that the BSP Kernel has everything which is needed to use the media decoder in the Pine64.

Cheers
Simon

This is a development that may please a lot of people, thank you for your efforts.

Yes, because Jens Kuske (jemk) has done the job, required for supporting Allwinner A64 - https://github.com/linux-sunxi/libvdpau-...e85f2c97c7 Wink
And it reused a lot of the earlier Allwinner H3 related code, that's why the Allwinner A64 patch is so small.

You should add that your Pine64+ is not even wearing a heatsink Smile

If you would spend the 50 Cent for an el cheapo heatsink then the temperature would be below 60°C already.

BTW: Using VDPAU you can then also use VLC (2.2.0 or above, no support for HEVC currently) or mpv to watch video HW accelerated (also in a desktop environment).

Done. I also forgot to mention that this temperature was HEVC [email protected] Decoding spreed-1080p.mkv which is HEVC [email protected] is 55-60C around 65C (again without heat-sink).

I tried VLC (from Ubuntu Xenial repository) and it does freeze with H.264 after a couple of seconds - so for now mplayer it is.

In Armbian we include an own mpv package since a few days:

Code:
[email protected]:~$ mpv --version
mpv 0.16.0-git-9d2980d (C) 2000-2016 mpv/MPlayer/mplayer2 projects
built on Sat Mar  5 16:11:21 EET 2016
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

I just tried it out with a desktop/GUI build for the old slow dual core A20, connected an USB disk that was lying around, double clicked a huge .mp4 and to my surprise even this 1080p/H.264 file was played absolutely smoothly on this old board. I will try to build a .deb for Pine64 the next days and post a link.

Thanks to jemk and longsleep.

Hi,
I'm really a n00b with this stuff, but I need to run RTMP stream smoothly on Pine64+ 2GB
Any suggestions how can I do this?
I've tried with mplayer, mpv, cvlc, and all of them are really slow, dropping frames and such.
I suppose any of them isn't HW accelerated?

Thanks! Smile

EDIT:
And I've tried to install vdpau, pixman and all dependencies.
And every time I get this error when trying to make and make install "libvdpau-sunxi": 
Code:
fatal error:"pixman.h: No such file or directory"

Any idea what's wrong? Thanks!

I am probably stating the obvious but you are missing 'pixman.h' in the include path.

Ye, kinda solved that.
But now when I try to play I get that this is missing: libvdpau_nvidia.so
