RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - matrzh - 2017-04-15

No, no cross compile . I compile on Debian (jessie).
The funny thing is: I added a '--verbose' to the ld-line in the makefile and I see all included libs when "collect2" is called. It's an enormous line with many libraries in there 2 or 3 times.
The order of the "cannot find -lxcb-xfixes" is exactly as in the command line that is printed.
However, it contains also lxcb without xfixes etc.
This does not seem to throw an error. libxcb.so.1 is in the exact same directory (and nowhere else on my system).
libxcb.so.1 is version 1, all the libxcb-xfixes.so.0 are of version 0. Could this yield conflicts? I tried to make a symbolic link and even a copy to libxcb-xfixes.so.1, but this did not work either.

--edit--

So stupid. For some reason the symbolic link libxcb-xfixes.so was missing in the library directory, it only had libxcb-xfixes.so.0 etc.... Confused
libxcb.so existed, however.

Compile went through Cool
I will let you know tomorrow, if it actually works Wink

Is it correct that there still seems to be some X11 stuff in it?

It's working in principle! I keep getting segmentation faults, after some time, though. Could be because I am running squeezelite in parallel that is also using ALSA and sound cannot be allocated. Will fiddle around a little and think I will get there. Thanks for your help!

check that your user running kodi is part of group "audio", otherwise kodi lacks the rights to open /dev/snd

do you have a backtrace from the segfaults? can you run kodi in gdb and provide the backtraces?

I am running as root to test, I know I shouldn't Wink

############# END STACK TRACE ###############

At one point, I had to repair my SD-Card filesystem which left some files corrupted and I had to reinstall some packages, including some python stuff, but I think everything is good again, now.
Do you see any shared library above that seems to be not working?
ldd -r works on all of them.

the last lines of the crashlog / logfile are as follows:

So the crash seems to be coming without many warnings. I can play some formats locally, but have not been able to play any web streams.
If it does not know how to display the stream, I would expect it to tell me instead of crashing with a segfault Undecided

Still no audio. I do not get any warnings / errors if I stop squeezeserver and squeezelite, but still have a red "no sound" logo on the top right and cannot make it go away.

I would also like to have sound via HDMI (soundcard with index 2). How can I tell Kodi? The selection under Settings->Audio is grey and cannot be selected.

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - mosterta - 2017-04-17

regarding the crash: the current (my) implementation expects that the library libvdpau_nv_sunxi.so.1 can be found in /usr/lib/vdpau. There is no fault handling done if it is in a different directory, but crashes with executing address 0x0000000 (which is the case in your backtrace). so check that the library is available in this directory.

regarding sound: have you checked with the program alsamixer, that the output is enabled and the volume is at a reasonable value? From your log file everything seems to be fine.
HDMI can be used in kodi via configuration in the settings menu (system/audio). When ALSA recognizes your HDMI output sink then you can choose the HDMI output sink there. When it is greyed out as in your case, then either Kodi does not recognize any sound device or within ALSA there is only one sink configured. You can see whether HDMI is available in the program alsamixer (you need to change the device via F6 key within the program). If there is no sndhdmi device available then your alsa configuration is not correct. please refer to how to configure ALSA. I do not know right now, since HDMI was recognized immediately on my Mele (A10) / bananapi / orangei.

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - matrzh - 2017-04-17

Thanks for the hint. I would not have been able to make any sense out of the backtrace.
Now I get a
kodi.bin: opengl_nv.c:352: glVDPAUMapSurfacesNV: Assertion `nv' failed.

In the file there is indeed the code "assert(nv)" on that line.
Any idea? In any case, the backtrace is a bit more meaningful, now.

As for the sound: In alsamixer I can choose the other cards, but I get a message "This sound device does not have any controls"
I suspect I am missing a kernel module (I may just have to load it, but need to figure out which).

Getting there, one step at a time Wink

---edit---
Just saw your previous post from the beginning of this thread where you mentioned to disable the vdpau mixing. It is now working !!
Still need to figure out the sound, and I do have a slight stutter every 2-5 seconds. Could be a streaming issue, but the internet is fast, in principle.
I also do see the cursor blinking on the top right. Is this normal or can this be shut off (it is from the login screen before starting kodi)

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - mosterta - 2017-04-18

very well. the stutter is from writting debug information into the log file (~/.kodi/temp/kodi.log). When you recompile without debug or disable debug the stutter should be gone.

the blinking curser must be disabled outside of kodi. I created a udevd rule which switched blinking off when the sysfs is loaded:
bananapi@bananapro:/etc> less udev/rules.d/95-sysfs.rules
#rule to switch off console curser blinking
KERNEL=="fbcon", SUBSYSTEM=="graphics", ATTR{cursor_blink}="0"

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - matrzh - 2017-04-22

blinking has gone and big improvements over the stutter when cutting off all debugging through the GUI.
Sound is being played over the headphone jack without problems. However, I cannot get it through HDMI which is the only thing left before I can actually enjoy kodi Wink
But I did not really progress here over the last days, as everything seems in principle fine:
I can stream sound through the HDMI card with speaker-test or mpeg321

aplay -l displays:

**** List of PLAYBACK Hardware Devices ****
card 0: sunxicodec [sunxi-CODEC], device 0: M1 PCM [sunxi PCM]
Subdevices: 1/1
Subdevice #0: subdevice #0

Subdevice #0: subdevice #0
card 2: sunxisndhdmi [sunxi-sndhdmi], device 0: SUNXI-HDMIAUDIO sndhdmi-0 []
Subdevices: 1/1

mpeg321 -o alsa -a hw:2,0 somemusic.mp3 works perfectly. However, Kodi only shows as audio output a greyed out, unselectable "sunxi-CODEC" (which goes to the headphone jack)
Any ideas?

As mentioned: the cards 1 and 2 can be selected in alsamixer, but do not have any controls (this is not displayed as error, but more as information and apparently at least the HDMI can stream).
It kind of seems reasonable that HDMI is digital and has no volume control, though.
I was stumbling over this http://alsa.opensrc.org/Softvol, but it seems a bit cumbersome and I cannot imagine that this is necessary to make Kodi work...

Is there any other place where I can set Kodi on passthrough mode, when I cannot select the HDMI?

I have found the issue: The devices are named differently when I look to different platforms A10/A20 (linux-sunxi kernel) and H3 (H3 kernel)

there is a sunxi dedicated whitelisting in the code, which searches for substring "sunxi" in the alsa device name. But the device names in H3 do not contain the substring "sunxi", while the A10/A20 device names do.
Which kernel are you using and which processor? (I just saw that your device have the sunxi substring - strange since the devices should be found. I will have a look at the code if the whitelisting is really required or can be done in a better way.
The other option is to install pulseaudio and try that. That worked for me as well, but since I do not have multiple sound generating applications I removed it from my system.

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - matrzh - 2017-04-23

Quote:there is a sunxi dedicated whitelisting in the code, which searches for substring "sunxi" in the alsa device name.
I am wondering, now...is there something missing in this code? I cannot find any "sunxi" whitelisting. I searched for the string in all *.h and *.cpp files.

I used the xbmc version from https://github.com/tnmeyer/xbmc branch Jarvis_vdpau_gles

With the info below, I was digging a little into the code and got to
xbmc/cores/AudioEngine/Sinks/AESinkALSA.cpp
Code:
.....
else if (baseName == "front")
      {
for (void** hint = hints; *hint != NULL; ++hint)
  {
    char *io = snd_device_name_get_hint(*hint, "IOID");
    char *name = snd_device_name_get_hint(*hint, "NAME");
    char *desc = snd_device_name_get_hint(*hint, "DESC");
    if ((!io || strcmp(io, "Output") == 0) && name
        && strcmp(name, "null") != 0)
    {
      std::string baseName = std::string(name);
      baseName = baseName.substr(0, baseName.find(':'));

      if (strcmp(name, "default") == 0)
      {
        /* added already, but lets get the description if we have one */
        if (desc)
          defaultDescription = desc;
      }
      else if (baseName == "front")
      {
        /* Enumerate using the surroundXX mangling */
        /* do not enumerate basic "front", it is already handled
         * by the default "@" entry added in the very beginning */
        if (strcmp(name, "front") != 0)
          EnumerateDevice(list, std::string("@") + (name+5), desc ? desc : name, config);
      }

      /* Do not enumerate "default", it is already enumerated above. */

      /* Do not enumerate the sysdefault or surroundXX devices, those are
       * always accompanied with a "front" device and it is handled above
       * as "@". The below devices will be automatically used if available
       * for a "@" device. */

      /* Ubuntu has patched their alsa-lib so that "defaults.namehint.extended"
       * defaults to "on" instead of upstream "off", causing lots of unwanted
       * extra devices (many of which are not actually routed properly) to be
       * found by the enumeration process. Skip them as well ("hw", "dmix",
       * "plughw", "dsnoop"). */

      else if (baseName != "default"
            && baseName != "sysdefault"
            && baseName != "surround40"
            && baseName != "surround41"
            && baseName != "surround50"
            && baseName != "surround51"
            && baseName != "surround71"
            && baseName != "hw"
            && baseName != "dmix"
            && baseName != "plughw"
            && baseName != "dsnoop")
      {
        EnumerateDevice(list, name, desc ? desc : name, config);
      }
    }
...
But if I do aplay -L, I get:
Code:

    sunxi-sndhdmi,

plughw:CARD=sunxisndhdmi,DEV=0
    sunxi-sndhdmi,

I do not really know the Alsa API and what the method 'snd_device_name_get_hint' does compared to aplay -L, but my guess is that this excludes all cards from the listing...
Default is somewhere defined before, I do not quite see where, but only the description is added (and I see the sunxi-CODEC sunxi PCM in the GUI).
Then, sunxisndhdmi and sunxisndspdif all have the excluded names as "base name".
Should I allow the "default"?

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - mosterta - 2017-04-23

it seems that the tnmeyer repository misses some code (for whatever reason), where in my repository this code is included.
This is the missing code (see else branch)

else if (baseName != "default"
&& baseName != "sysdefault"
&& baseName != "surround40"
&& baseName != "surround41"
&& baseName != "surround50"
&& baseName != "surround51"
&& baseName != "surround71"
&& baseName != "hw"
&& baseName != "dmix"
&& baseName != "plughw"
&& baseName != "dsnoop")
{
EnumerateDevice(list, name, desc ? desc : name, config);
}
else
{
/* sunxi whilelist */
std:Confusedtring strDevice = std:Confusedtring(name);
size_t found = strDevice.find("sunxi");

if(found != std:Confusedtring::npos)
EnumerateDevice(list, name, desc ? desc : name, config);
}

This white listing does work for your kernel, you will see a lot of devices in Kodi (this is an Ubuntu bug, whereas I use openSuse which does not have the issue). A fix including Ubuntu is to restrict the white listing for the device "sysdefault".

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - matrzh - 2017-04-23

It's working! I added the code and filtered for baseName=="sysdefault" and have 4 devices showing (default and the first being identical). You are my hero Wink
Now I still need to compile without debugging enabled and hopefully I can get rid of the out of sync problem between audio and video.
Thanks again

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - mosterta - 2017-04-24

you're welcome.
Now that you have been able to compile that version and enjoying the videos, you can do your next step and compile kodi version 17.1 with improved video output. The GLES version is based on Kodi 16.x and has performance issues with full HD video resolution. In the kodi version 17.x I have replaced the GLES output by using a more hardware centric approach (i.e. I used the hardware layer mechanism instead of build the layers via OpenGL). This version displays videos much smoother, especially in Full HD resolution.
I don't know whether it is in the tnmeyers respository, but it is in mine on the branch "master_allwinner_layered_vdpau". So if you want to compile a bit more and even get a better experience on watching videos, then try this one.

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - matrzh - 2017-04-27

Hi. I succeeded to compile your version, but now I get again Segmentation faults when trying to play the videos.
Actually, before I tried to turn off debugging in tnmeyer's version (which remained in there in a really stubborn way, trying it with advancedsettings.xml etc., but this also led to a crash.
It could be that Libudev was additionally configured after I cleared the cache?
crashlog is will be added below.
I cannot see any unresolved lib-calls, but I am a little guessing around, here...

Your compile went through very smoothly. However, I tried a previous version of yours before I checked out the master_allwinner_layered_vdpau that had an old ffmpeg. could it be corrupted?

Your compile went through relatively straight forward Smile
In xbmc/windowing/egl/EGLNativeTypeA10.cpp I had to comment out #include <os_adapter.h> and get drv_display_sun4i.h from a cedarx-lib that I found somewhere (may I could also comment it out, did not try).
xbmc/cores/VideoPlayer/DVDCodecs/Video/Makefile did not have HwBufferAllwinner.cpp in the source variable.
and my sunxi_disp_ioctl.h was in the video subdirectory whereas you include it from the linux subdirectory in HwLayerAllwinnerA10.cpp
Probably a kernel difference? (I am on 3.4.111)
