Sure, with VDPAU it looks good, but my hardware can only bring me up to around 12 fps... (Asrock E350M1 (Fusion) )

Crossing my thumbs that this will be fixed further ahead, but for most movies current support is great!

Thanks spocky184 will try this. I think the key is to add these lines and the 11.8 drivers.

I think I had some Problems with the xorg.conf and the refresh rate. @spocky184 could please write me an PM with your xorg.conf? Or perhaps a screenshot of the ati control center. Could perhaps help me. In xbmc, are you using the "Adjust display refresh rate to match video " option?

Quote:Controll if you have also these two sections in /etc/X11/xorg.conf:
Code:

Section "Extensions"
Option "Composite" "Disable"
EndSection

Section "ServerFlags"
Option "AIGLX" "off"
EndSection

I build the mainline yesterday with the patches from FernetMenta, it also works quite well. The "big pixels" I also noticed in some videos.

Seems everything is getting well :-)

@ErikB

I too have the "big pixel" affect on some 1080p and it's definately related to the level that FernetMenta mentioned. My ramblings here documents my findings

So, today I'm thinking about doing the same process but with ubuntu server instead of ubuntu desktop. Will I succeed?

Why, you ask?
Because when performing installation like i mentioned before - I run too low on disk space. I have a 16GB USB stick, which was partitioned to leave 3GB for linux-swap etc, and in the end i have less than 1GB free when everything is installed. not enough, sadly.

So, any advice not-to do it before I start?

- Balinus - 2011-09-06 19:43

ErikB, I'm surprised that you only have 1GB left after your installation. 16GB should be more than plenty for Ubuntu desktop version.

Side question : Is there a lot of files that are encoded in "H.264 content over HP@L4.1" ?

No, but that seems to help if you have stuttering playback while playing mkvs.

Actually I got it to work even in the ubuntu server!
Just basically the same procedure as before, only using a minimal amd64 install!

Code:

(first - minimal install of ubuntu server 64bit) 

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install wget dh-modaliases ia32-libs

apt-get install dkms 

apt-get install xorg

cd ~; mkdir catalyst11.8; cd catalyst11.8

wget http://www2.ati.com/drivers/linux/ati-driver-installer-11-8-x86.x86_64.run

chmod +x ati-driver-installer-11-8-x86.x86_64.run

sudo sh ./ati-driver-installer-11-8-x86.x86_64.run --buildpkg Ubuntu/natty

sudo dpkg -i fglrx*.deb

sudo aticonfig --initial -f

sudo aticonfig --input=/etc/X11/xorg.conf --tls=1

reboot

sudo apt-get install -y libkms1 libdrm-dev pkg-config vainfo

cd ~

mkdir vaapi; cd vaapi

wget http://www.splitted-desktop.com/~gbeauchesne/xvba-video/xvba-video_0.8.0-1_amd64.deb

sudo dpkg -i xvba-video_0.8.0-1_amd64.deb

cd /usr/lib/dri; sudo ln -s /usr/lib/va/drivers/fglrx_drv_video.so fglrx_drv_video.so

sudo nano /etc/environment

insert:

LIBVA_DRIVER_NAME=xvba

LIBVA_DRIVERS_PATH=/usr/lib/va/drivers

sudo reboot

sudo apt-get install python-software-properties

sudo add-apt-repository ppa:lars-opdenkamp/xbmc-pvr

sudo apt-get -y update

sudo apt-get install xbmc

sudo adduser xbmc video

sudo adduser xbmc audio

reboot

xinit xbmc

Now I just need help how to get the server to automatically run "startx" upon boot. Right now I need to ssh into the server and run startx to run.
How can I get it to run that by it self?

When I boot the server, the monitor connected to the server only shows a blinking "_" in the top left corner - until I ssh to it and run startx.

Thanks

maybe try this:

Code:

echo 'case "`tty`" in' >> ~/.bash_profile

echo '   /dev/tty1) clear && startx &>/dev/null;;' >> ~/.bash_profile

echo 'esac' >> ~/.bash_profile

and if you also want to start xbmc automatically:

Code:

echo 'exec xbmc --standalone' > ~/.xsession

only tested on ubuntu alternate not on server installation.

hope that helps

Thank you, but I don't really succeed..
What happens is that the server boots, quickly splashes the "ubnutu 11.04" loading background, goes to black with a _ in top left corner for a few seconds and then goes all black. Seems like it started startx, but does not start xbmc or any console there, just goes black.

If I dont add contents to .bash_profile screen stays in blinking "_" - mode.

BUT! I've found another solution.
I can boot the server, with no .bash_profile, and then connect with ssh, and then run "startx&".
The & makes it run in the background and then I can logout from ssh and xbmc keeps playing on my server. Nice.
Only drawback is that whenever I reboot I need to ssh to start xbmc.

Strange, should be able to automatize something like that.

ErikB Wrote:Strange, should be able to automatize something like that.

Actually, you can. By doing this!
create a file, for instance xbmcstarter, and put it in /etc/init.d

Content:

Code:

#!/bin/sh

startx

And finally run chmod +x xbmcstarter

When starting the server like this, xbmc starts after bootup.. but when starting a movie xbmc instantly restarts, for some reason.
Guess there is some difference between starting from /etc/init.d and from ssh...

EDIT: Maybe it has to do with the fact that startx is run as root instead of as xbmc - and root doesnt have video or audio privileges.. Will try adding root tho those groups tonight. (or maybe the other way around or something else login-related)
