Add VPU support for HW-accelerated video decoding #1

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
If we cannot get ahold of the source code; we might be able to use the 
precompiled binaries from Android (the libvpu and dependent libs) and write a 
wrapper for video acceleration... maybe.
That could be hard to achieve, but it is doable I think.

Are we missing the VPU code from the kernel source? (I saw the config option 
for VPU; but I did not look for the source and did not try to compile it)

Tried enabling VPU but, as expected, some sources seem to be missing in kernel.

Seem to be missing vpu_service.c (and dependents) --> 
arch/arm/plat-rk/vpu_service.o

This could be of interest....

Maybe we should contact this chenhengming:

robert@owllap:~/projects/rk3066/rk3066-kernel/arch/arm/plat-rk/include/plat$ 
cat vpu_service.h 
/* arch/arm/mach-rk29/include/mach/vpu_service.h

I dont know if you are still missing the vpu_service.c but it can be found here:

vpu_service.c

Hi everybody!
Is there any progress with this issue? I can try to help with the 
implementation of h/w decoding implementation cause I have an MK808 device with 
this chip on board and anyone will point me on where to start from for a quick 
start.

So, Is it possible to make working vpu ?

Original comment by sahab.a...@gmail.com on 8 Jun 2013 at 3:44

GoogleCodeExporter commented 8 years ago 
I think at least we can try. If the VPU sources are compilable and working (see 
comment #8) then everything is much better than it could be otherwise.

This is the showstopper. 90% of the people will use picuntu solely for xbmc.

Hey, we are trying to collect as much information as possible on this as to get 
video acceleration some day.

We have also opened a mailing list to coordinate efforts:
