@whitewind
Whats your CPU usage when you play this 720p video?

When playing 720p:
kodi.bin: 150%
X: 45%
When playing 1080i:
kodi.bin: 180%
X: 25%

Could you say what are You patching in libMali.so ?

<__egl_platform_swap_buffers+40> ldr r3, [pc, #36] <__egl_platform_swap_buffers+42> movs r2, #0
<__egl_platform_swap_buffers+44> add r4, sp, #24 ; There was #28
<__egl_platform_swap_buffers+46> add r3, pc
<__egl_platform_swap_buffers+48> ldr r0, [r3, #4]
<__egl_platform_swap_buffers+50> movs r3, #0
<__egl_platform_swap_buffers+52> str r4, [sp, #16]
<__egl_platform_swap_buffers+54> strd r2, r3, [sp]
<__egl_platform_swap_buffers+58> strd r2, r3, [sp, #8]
<__egl_platform_swap_buffers+62> ldr r0, [r0, #4]
<__egl_platform_swap_buffers+64> bl 0xb6f5cf64 <DRI2SwapBuffers>

Copy code

See comment in line <+44>
I think it's a bug in call to DRI2SwapBuffers. I'm not sure, but it seems that last parameter is something like some_struct *s and someone passed wrong pointer, so stack gets corrupted when DRI2SwapBuffers tries to write something to &s

This is software decoding.

Yes, but this is hardware rendering. With software rendering it wasn't possible to play HD videos with reasonabe FPS

So basicly , GPU is doing some work, but actual h264 is still inactive.

The only thing that bothers me is that Kodi segfaults somewhere in libc from time to time. I'm using kodi-odroid, so I'll try to rebuild from source.

Here is my repository with patched libMali.so, updated headers and pkg-config files from @raoulh:

And what are You thinking about eglSwapBuffers not DRI2SwapBuffers

Guys you won't have hardware video acceleration fo kodi working with mali !!!
Mali is for "3D" accel ...

Please enlighten me because I don't understand.
Mali is the Orange PI GPU, right ?
Is any other "Processing Unit" used (and working) for
hardware video acceleration in Kodi for Android ?
