How to Install XBMC PVR Xvba for AMD/Nvidia/Intel GPUs

Quote:The Killa sampla runs perfectly except that at ~7secs the screen goes black for about 1/10 sec if I have enabled A/V sync

Note that killa samples switches fps. It start with 23.976, then switches to 23.952

->> CalcFrameRate framerate was:23.976024 calculated:23.952096

This triggers re-configuration of renderer.

For now I could only test this with E350, E450 on Ubuntu 12.04 and flgrx 12.6b.
Make sure to really X stoppend, when you modify amdscdb.

Great! So the post on phoronix actually worked... Thanks for all efforts to make AMD the best x86 HTPC chips.

Testing as we speak, with the killa sample and some horribly encoded anime DVD @ High@L5.1 >_>.

Edit: both work fine . 9% on CPU0, 36% on CPU1.

Having a hard time finding samples that are bad enough.. I found a bunch of samples here and tested War Horse which is 1080p L4.1 with 5 ref frames. I also tested a 720p sample which was L3.1 with 5 refframes. Unfortunately neither had defects even with yesterday's setup.

A sidenote: I wonder how people manage to create out-of-spec videos. I e in Handbrake there are no instructions that say you should avoid refframes >4, but there's also nowhere to select level, I think it sets level automatically based on your other choices.

@Robotica:
It was a kind of "libamdxvba.so" reengineering :-). I found that key months before - but always enabled it at the wrong position :-). But happy it works now.

As Kano pointed out, this should also work while xserver is running:

Nice works great! Only thing left now is the HD audio :-)

@DavidGGG:
It is not only reframes. At 720p you can do alot more. See the latest patch in fernetmenta's trunk. There you see a calculation.

EDIT: Easier method: thx Kano for pointing this out

Code:

sudo amdconfig --set-pcs-u32=MCIL,HWUVD_H264Level51Support,1

alternative method:

Code:

sudo service lightdm stop
sudo cp -p  /etc/ati/amdpcsdb  /etc/ati/amdpcsdb.bak
sudo sed -i '/UvdEnabled=V1/ a HWUVD_H264Level51Support=V1' /etc/ati/amdpcsdb
sudo reboot

Please report back with results and following info:
- What GFX card do you use
- uname -a
- dpkg -l | grep fglrx

I'm having a Zotac AD02 with OpenELEC on it so just entering this command in console should be enough?

sudo amdconfig --set-pcs-u32=MCIL,HWUVD_H264Level51Support,1

Is there a way back in case it fails?

@schumi2004:
yeah, there is an easy way back:
Disable: sudo amdconfig --set-pcs-u32=MCIL,HWUVD_H264Level51Support,0
Enable: sudo amdconfig --set-pcs-u32=MCIL,HWUVD_H264Level51Support,1

Btw. some users could not get this work with a running X. I talked to a gentoo guy yesterday.
So, if /etc/ati/amdpscdb does not enable it at all, please do the following:



@All:
Catalyst 12.6 final was released. I could not get it running on either E350 or E450. You get a green unsupported watermark (yeah, could remove this). Worse aticonfig tells you "Unsupported Hardware" and does not do any settings. So I would suggest you waiting for an upgrade, till these things are sorted out. I did not have enough time yesterday night to see what additional files are missing, to workaround this behaviour. I downgraded to 12.6b.

afaik openelec does not use sudo, so just run as root. setting it to 0 disables it again. You can also backup for driver config as shown in the alternative method.
To be sure, ask the openelec guys
