RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - porlock - 2016-03-31
I use kodi from Tom81 that is https://github.com/tnmeyer/xbmc branch "Jarvis_vdpau_gles"
./configure --config-cache --prefix=/usr/local --disable-x11 --disable-sdl --disable-xrandr --disable-joystick --disable-gl --enable-vdpau --disable-vaapi --disable-openmax --enable-neon --enable-gles --disable-mysql --enable-airplay --enable-airtunes --enable-debug --enable-optimizations --with-ffmpeg=force --with-platform=allwinner-mali
I use a libvdpau-sunxi from https://github.com/mosterta/libvdpau-sunxi master branch
I revert te commit b709664 recompile and install libvdpau-sunxi but no luck it crash anyway

@tom81 Hi! I'm trying to compiling your version of xbmc and I got stucked in a very strange linking problem;
Quote:/usr/bin/ld: xbmc/windowing/egl/windowing_egl.a(EGLWrapper.o): undefined reference to symbol 'eglTerminate'

I strictly followed the build procedure in first post and all object file have been built.
It just failed in linking kodi.bin
did I missed something or did something wrong? Please help me!
PS: I believe symbol does exist in libEGL_Mali.so

RE: hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy) - tommy6555 - 2016-05-08
Hi all,
I'm trying to build Kodi on a A20-OLinuXIno-LIME2-4GB platform.
I created a libavcodec/vdpau_msmpeg4.c file with only an empty main function to workaround the missing file problem and now the Kodi building stops with the following message:
/xbmc/tools/depends/target/ffmpeg/ffmpeg-install/lib/libavcodec.a(allcodecs.o): In function `avcodec_register_all':
/xbmc/tools/depends/target/ffmpeg/ffmpeg-2.4.6-Helix/libavcodec/allcodecs.c:361: undefined reference to `ff_msmpeg4v3_vdpau_hwaccel'
collect2: error: ld returned 1 exit status
Makefile:533: recipe for target 'kodi.bin' failed
make: *** [kodi.bin] Error 1
I tried googling for the "undefined reference to `ff_msmpeg4v3_vdpau_hwaccel' " error, but I did not find anything about it.
Do you think this error is still due to the lack of the true vdpau_msmpeg4.c file?
Thanks

As I replied over here http://forum.kodi.tv/showthread.php?tid=251413 perhaps a better idea for acceptance would be to port this from VDPAU to a other API like example OpenMAX instead?

OpenMAX codecscan be made compatible with OpenGL & OpenGL ES, ARM & x86, Linux & Android.
It's technically possible to use this piece of software with kodi, but it needs some adaptions. We cannot use it directly as a VDPAU backend, because KODI uses the nv_gl_interop feature. This is missing on ARM, because we have OpenGL/ES here and btw. vdpau wasn't designed to be used on arm anyway.
....
Another one would be, to drop the vdpau idea and write our own decoder class, using the knowledge of reverse engineering, that is implemented in the libvdpau-sunxi backend already.
https://www.khronos.org/openmax/
And by that I am not suggesting to just write a OpenMAX wrapper for the VDPAU backend, but instead to actually make native OpenMAX codecs for Allwinner which does not rely on VDPAU at all.

It should however be noted that VAAPI, like VDPAU, is designed for x86, not ARM. Which is why I suggested OpenMAX instead of VAAPI, and strongly suggest to checkout OpenMAX for Allwinner.

I am not really familiar with openmax, but do you have zero-copy approach from hardware to the display engine? And I don't mean OpenGL(ES) output (because Mali/memory bandwidth is too low for full HD), but access to the disp device/hardware layer to display the decoded frames with zero-copy..
this is crucial if you don't have much power as on an A10 or A20..

This headers must to be used for building Kodi not only for libvdpau, so it is needed do put them in system patch tree.
I successfully build Kodi, now im fighting with a krenel, it was compiled successfully but stuck on bootingi'm searching what can cause that.
Hi porlock,
I've same problem compiling DVDVideoCodecFFmpeg.cpp (error: ‘EGLSyncKHR’ does not name a type EGLSyncKHR fence)...what do you mean when you say "so it (the headers) is needed do put them in system patch tree."? Could you give more details about what you have done?
For the record: I've built my own kernel with mosterta's patches and followed succefully twisted_tits's tutorial (https://twistedlinux.wordpress.com/2016/03/14/build-a10a20-with-hardware-acceleration/). I've tried to use CFLAGS pointing to the new EGL headers to compile Kodi, but i had no success at all...
Could you help me budy??
Thanks in advance for yours great jobs guys.

sergiodefontes,
You need to put the libraries from https://github.com/codesnake/aml-mali/tree/master/include in /usr/include in your system, preserving the folder structure, i.e. you should have /usr/include/EGL, /usr/include/GLES and so on with respective files inside.

Valentin

sergiodefontes, wrong libMali.so. You need the framebuffer version, not the x11 one.
