Thank you again mapmot, I have apreciated your concern about my (newbie's) questions. I'll try to solve this mistake and give you a feed-back soon.

Best regards,

Hi guys,

I'm back to give you a feed back of my Odissey building a hardware acelerated version of Debian/Kodi to my Bananapi.

I followed the mapmot's sugestion (thks fellow) doing the right way to build a libmali.so framebuffer version.

In my case, to do that, I built sunxi-mali using the following parameters:

make config ABI=armhf VERSION=r3p0 EGL_TYPE=framebuffer

After that I could lauch Kodi successfully, finaly.

But, I realized that I couldn't play videos because of the following error:

Code:
root@bananapi:~# kodi

Playing: /media/HDExterno1/home/sergiodefontes/Downloads/test.mp4

[lavf] Using subtitle charset: ISO-8859-1

 (+) Video --vid=1 (*) (h264)

 (+) Subs  --sid=1 'Test.pr.srt' (subrip) (external)

[vo/vdpau] Error when calling vdp_device_create_x11: 1

Error opening/initializing the selected video_out (-vo) device.

Video: no video

Exiting... (Errors when loading file)

In other words, I've got the same problem reported by porlock at his post #108.

I tried to follow the subsequent posts, but however, to me, the solution was not clear.... then I've searched on Internet for a solution, spending a lot of time, unfortunely without success...

That's why I ask for you help again....sorry about that...

Well, I'm using sunxi-mali from Mosterta's git: https://github.com/mosterta/libvdpau-sunxi, building it following those steps:

Code:
$cd /root/Sources/video_acceleration

$git clone https://github.com/codesnake/aml-mali

$cp aml-mali/include/EGL/eglplatform.h aml-mali/include/EGL/eglplatform_fb.h

$git clone https://github.com/mosterta/libvdpau-sunxi

$cd libvdpau-sunxi

Edit ve.c - comment the lines bellow

                 #include <valgrind/ammt_reqs.h>

                    VALGRIND_PRINTF("regs base addreess=%p\n", ve.regs);

                    AMMT_SET_REGS_BASE(ve.regs);

           - include line 

             #include <string.h>

Edit opengl_nv.c - replace mem.mem_id with mem

Edit Makefile - change LIBS_VDPAU_SUNXI = -L /usr/local/lib/vdpau -lvdpau_sunxi

Edit h264.c - include line #include <stdio.h>

Edit mpeg12.c - include line  #include <stdio.h>

Edit mp4_block.c- include line  #include <stdio.h>

Edit presentation_queue.c - include line  #include <stdio.h>

$make CFLAGS="-I/root/Sources/video_acceleration/sunxi-mali/include -I/root/Sources/video_acceleration/aml-mali/include "

$make install

cp -v /usr/local/lib/vdpau/libvdpau_nv_sunxi.so.1 /usr/lib/

cp -v /usr/local/lib/vdpau/libvdpau_sunxi.so /usr/lib/

cp -v /usr/local/lib/vdpau/libvdpau_sunxi.so.1 /usr/lib/

cp -v /usr/local/lib/vdpau/libvdpau_trace.so /usr/lib/

cp -v /usr/local/lib/vdpau/libvdpau_trace.so.1.0.0 /usr/lib/

That's my building log: http://pastebin.com/G39fasMe

Running vdpauinfo I have:

sergiodefontes, try libvdpau-sunxi from here: https://github.com/tnmeyer/libvdpau-sunxi, should compile and install without modifications.

The lack of feedback is good feedback. sergiodefontes is probably enjoying watching movies on his Bananapi Big Grin

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - RockerC - 2016-12-15

Can I ask why a VDPAU based solution was chosen over a VAAPI based solution for this implementation?

I know Team Kodi developer fritsch have been working hard for a very long time at perfecting VAAPI in Kodi.

See. http://forum.kodi.tv/showthread.php?tid=231955 (and older thread http://forum.kodi.tv/showthread.php )

Just asking because would think that a VAAPI based solution might see a broader adoption of this, or?

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - rellla - 2016-12-15

Maybe because libvdpau-sunxi was already there and it was easier to extend vdpau instead of writing a new userspace backend.

I have been able to compile and run Kodi following the instructions in this thread, I had several issues resolved by reading it all. However I get a segmentation fault when I try to watch a movie and I am stuck at this point:

Code:
# kodi

Segmentation fault (core dumped)

This is the crash report http://pastebin.com/m5cKhv3M

And some info about my system.

The machine is a Cubieboard 2 using armbian and a recompiled kernel with the CMA config

I use kodi from @tom81 https://github.com/tnmeyer/xbmc branch "Jarvis_vdpau_gles"

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - maggette - 2017-01-07

I have now tried to delete all libvdpau libs, recompile and reinstall. Interestingly I see this when trying to play a video:

Code:
Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory

Which I forgot I tried "fixed" it before by linking to libvdpau_sunxi.so, but it looks like there is a problem here. Why is vdpau trying to load libvdpau_nvidia.so?

Thank you in advance

I've just resolved this problem by doing this in the cli: export VDPAU_DRIVER=sunxi

However I still get a segmentation fault as before when trying to play a video.

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - maggette - 2017-01-08

I have tried it now but I get the exact same segmentation fault. I realized that this problem is exactly the same one that is mentioned by @rellla in the post #115

Code:
#1  0x004602dc in VDPAU::COutput::GLInit (this=this@entry=0xb002bb10) at VDPAU.cpp:4071

But it seems it was never resolved.

I'm going to try to compile kodi 14.2 by @mosterta

I was able to fix the segmentation fault, reading the VDPAU.cpp file I saw it was trying to find the vdpau libraries in /usr/lib/vdpau/ so I copied them from /usr/local/lib/vdpau/ and even I have been able to reproduce 1 video that before was crashing.

However for almost every video I play I'm getting this same error described here, but disabling the VDPAU mixing didn't fix my problem. Any other hints?

Kodi starts up alright, but as soon as I start some video playback, it crashes and I get the following on my console:

Code:
kodi.bin: opengl_nv.c:348: glVDPAUMapSurfacesNV: Assertion `nv' failed.

What's wrong?

Please disable in Kodi settings VDPAU mixing, but keep VDPAU itself enabled.

check that you have the correct (i.e. framebuffer based opengl library in you LD Libarary path)
