I took the EGL includes from the Amlogic Mali libraries which had all the necessary defines. Some other things needed modifications to get your kodi version to build. Here's the patch against your github tree: http://pastebin.com/8xb52BgX

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?

the question is not studid, this is something I already forgot about: I modified valgrind to add more features, but which you probably don't need. you can remove the include line + in ve.c the line with
AMMT_SET_REGS_BASE.

Thank you for your answer. I've already tried to remove "#include <valgrind/ammt_reqs.h>" in ve.c, now i've tried to remove "AMMT_SET_REGS_BASE(ve.regs);" line also. But i end up with the same error:

At first i thought it is because i have X11 version of mali driver, so i install it for framebuffer, but the file is still missing. So i manually create file eglplatform_fb.h in /usr/include/EGL, with the content from here - sunxi-mali/include/EGL/eglplatform_fb.h and i make some progress, but end up with another missing file error:

I tried the same scenario and manually create the file in /usr/include/EGL, with the content from here - fbdev_window.h @ 3bf3af7b, but still something is not right because i end up with another error:

for which i don't have an idea. I will appreciate if you give me some more clues .

Yes, this almost do the trick, thank you. But i had to rename/copy eglplatform.h as eglplatform_fb.h, because i noticed it is the same file, renamed when i install mali driver for framebuffer. After this, the error was about missing vdpau-sunxi in ld or something, so i installed libvdpau-sunxi from here first, then your version finally make and installs without errors. Now i have new libvdpau_sunxi.so and some libvdpau_nv_sunxi.so.1 in /usr/local/lib/vdpau. I also copy vdpau directory in /usr/lib as is mentioned in above link, do ldconfig, reboot etc.
The problem is i can't use this new version for some reason. When i try to open file with mplayer or check with vdpauinfo i have an error:

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

Is this some permission problem, or something else?

I got it working now, disabling the video mixer solved my problem. So I did some tests with a number of video files, mainly h264 1080p and 720p. I also tested XVid and MPEG2 videos.
Results:

- H264 stuff generally works up to 1080p (as expected), but I had to decrease ve_size in sunxi_cedar_mod to 80MB or lower (I had 128MB), otherwise 1080p playback crashes Kodi and

Code:

[ 3567.081631] UMP<1>: Failed to allocate needed CMA memory 401408 bytes
[ 3567.087041] UMP<1>: _ump_ukk_allocate() failed in ump_ioctl_allocate()
[ 3567.092643] UMP<1>: Failed to allocate needed CMA memory 1597440 bytes
[ 3567.098820] UMP<1>: _ump_ukk_allocate() failed in ump_ioctl_allocate()

appeared in my kernel log. sunxi_cedar_mod grabs mem in CMA when loaded, maybe vdpau-sunxi tries to grab another chunk of CMA via UMP and fails? Does vdpau-sunxi use the mem allocated by sunxi_cedar_mod?
- H264 and XVid files played fine, but I noticed some skipping every 20secs or so. The video freezes, about 4 frames are skipped (according to counter), then playback continues.
- MPEG2 videos fail completely, audio plays fine but there's no video at all.
- CPU usage is a bit higher as compared to the old AW blobs, around 30% on both cores (blobs had ~10%). Shouldn't be so important though.

I uploaded some kodi log files for the different codec playback attempts, maybe they help solving the stuttering and MPEG2 issues.

Hope this helps a bit.

(2016-02-07, 21:19)tom81 Wrote: Thanks for the feedback. I tested your updated code and I can confirm that MPEG2 video playback now works. Without debugging compiled in, the stuttering is also gone.
Some more things I noticed:
- Your latest FFMPEG patch seems to be missing a file, avcodec/vdpau_msmpeg4.c. I re-added it from an earlier revision of the patch.
- Forward/backward skipping in videos is broken for any codec: If I fast-forward the video to some different time, I get some green flashing screen with the last few shown frames repeating in between over and over again. Audio continues to play normally, though.
- XVID/MPEG4 playback seems to be a mixed bag. Some files I have work nicely, others have some sort of block artifacts, tearing, choppy playback or no video at all. Maybe the options the videos were encoded with are important, I'll try to produce some "broken" test videos for debugging.
I also tried to port your code to the latest Kodi version (16rc), but I'm afraid I messed something up: I only get a red screen instead of any hw-accelerated video. Something important has changed between 14.2 and 16 I didn't take care of...

Best,
tom

(2016-02-05, 15:24)mosterta Wrote: libvdpau_sunxi.so is loaded by libvdpau. It determines that from the location of its installation and adds the path vdpau (e.g. libvdpau in "/usr/lib" then libvdpau_sunxi.so must be installed in "/usr/lib/vdapu") (all AFAIK, since I dont have the code here)

There is also a hardcoded path for libvdpau_nv_sunxi.so.1 in kodi: This lib is currently expected to be in /usr/lib/vdpau. (AFAIK)

(2016-02-07, 22:47)mosterta Wrote: Cool, you tried already porting it. I tried to intermediate step to 15.2, BUT a/v sync in 15.2 has changed a lot and video display skipped lots of frames. Then I wanted to skip 15.2 and concentrate on the latest 16rc, but I did not even start. Maybe be can do the port to 16rc together.. Btw if you see a red screen when you display a video, this means that all values in the UMP buffers are 0. Then after YUV to RGB conversion within the GLES shader the color get converted to red.
I had a similar problem in CLinuxRendererGLES::Render. Check that
- the textures are uploaded to OpenGLES by a function with name similar to uploadTextures
- for single pass rendering that there is NOT just the bold marked line. RenderSinglePass called with the parameter m_currentField uses the wrong index, hence the wrong (empty) texture is used. Therefor I have added the RenderProgessiveWeave function, which uses a different index (internally)
case RQ_SINGLEPASS:
if (m_format == RENDER_FMT_VDPAU_420 && m_currentField == FIELD_FULL)
RenderProgressiveWeave(index, m_currentField);
else
RenderSinglePass(index, m_currentField);

VerifyGLState();
break;
