[LINUX] HOW-TO use VAAPI HW Acceleration on AMD Zacate (Fusion) platform

It's working fine on my Zotac zbox nano ad10 system.

Just tested it on my HTPC. Worked fine this time .
Only tested it for a few minutes but I noticed the following:
1) Overscan wasn't set properly in Ati CCC. I changed it by logging in to the desktop but a reboot resetted it.
2) Wake on USB doesn't work.
3) The remote stops working after suspending the machine.

I also had these issues on my own Ubuntu installation but didn't have time to fix them yet. Compared to my own Ubuntu install on USB stick this LiveCD boots crazy fast.

There is especially a difference in doing deinterlacing.

If Shared surfaces are disabled & interlacing:
Image data is loaded into a pixel buffer object and deinterlaced in there with opengl the resulting texture is passed to the output
else
Image data is loaded into a pixel buffer object and a texture created and output

With shared buffers disabled you have more CPU Load in both cases (interlaced and non interlaced content), but it works more stable.

Shared Buffers enabled:
Directly passed out by fglrx stuff. Less CPU Load, cause nothing has to be done in between.

if yes, try to toggle fullscreen to window mode and back. After a few secs it should work.

That works, but only when I toggle to windowed mode. Switching back to fullscreen introduces flickering/artifacts. Any idea when new version is released on PPA or when building from GIT source is once again possible? It does seem quite promising thus far.

Hi !

As you maybe know I am trying to make life easyer for Intel users with some guides, patches for VAAPI decoding and other testing stuff with Intel and kernel developers.

I am really impressed what you did here with the AMD support of XBMC. Now it looks quite perfect which was a complete mess months ago before you started working on it. Congrats to all the work done on this !

On Intel side it is also getting better and better. The only thing we miss is VAAPI deinterlacing. Work is already begun, but I am afraid that it will be a long time till we can get that work.

Until that I was thinking to do a software or OpenGL based deinterlacing.
the problem is that i am not so experienced in this area of programming, but I am learning.

Do you think that the way you do it with XVBA, so that deinterlacing is done with OpenGL, can be possible also with VAAPI ?

Thx, Cheers, Alan

VAAPI is really impressive. I installed the htpc of a friend four days ago using your howto on an intel sandybridge system. It works perfectly.

For the deinterlace code. This code was entirely written by Fernetmenta. I am all over happy to understand in the mean time what is going on in there.

But i think it can be adapted more easy than coding the VAAPI internal way, cause the structure and architecture should totally be the same.

I sorted the specific patch out for you:

I'm glad that it worked for you. It will become even more simpler with Linux Kernel 3.2 and even with 3.3.

Thanks for the help. I'll look at it and try to implement it for VAAPI. THANKS

Fritsch pointed me to the fix, switching off Compiz fixes all my issues.

Hello,

It looks like you guys are working really hard on getting hardware acceleration working. I am thinking about buying a AMD fusion system and have been having trouble working out if the hardware acceleration is at a point where it's worth buying a fusion board.

I have no problem compiling xbmc from source etc. So I was hoping if someone could tell me if the hardware acceleration is at a point where it can be used for 1080p playback?

Sorry if I am asking a question that's already answered somewhere else, in that case my google skills are not what they once were!

Thanks

you don´t need to compile it, only if you like to . VAAPI support for HD playback is working very good now. I personally like M´troys guide (page 67) to start with (or you wait for the livecd).
Even better should be XBVA support, but i haven´t tried it yet (there is a new thread about it).

How do you set/configure this? I'll add this to the next version.
