So now I'm looking for a ppa providing the libva package too, that will add the h264 support...

Your problem is not the version of the libva library. It is that your intel drivers are outdated. Just use the xorg edgers ppa, the way i did it in the guide.

BoBeRzE Wrote:@ alanwww1
is it necessarily to add ppa:team-xbmc-svn/ppa an a few stps later ppa:lars-opdenkamp/xbmc-pvr? Or need we ppa:team-xbmc-svn/ppa to install libva1 libva-driver-i965?
bye BoBeRzE

I reworked the complete guide and tested it on a minimal Maverick install. Sorry for the fist one. That had some things missing or confusing. SHould be ok now.

But what's not working for my setup is my television switching modes, I mean: when I play a 23.something movie my tv used to switch to 24p mode. And when playing a DVD my tv used to switch to 50Hz mode. That was with a Nvidia card. But I cannot get that to work on my new computer. Could you please let me know whether you got that working?

Yeah i have the same problem. I added this to the "not working" list.
I found out that the problem is not in xbmc. It is already there when X starts. I checked the xorg.log and there is only one refresh rate read out from the EDID data. I think this is closely related to the hdmi multichannel lpcm problem. The available screen and audio modes don"t get properly read.

The annyoing is that i can not set fixed modelines to use here. I tried it in a way we did it with nvidia cards, but nothingg happens. You can check the available refresh rates if you run xbmc in standalone mode with the --standalone switch. This way at video settings you can "choose" from the available one rate. This is the xorg.conf i tried. But i think this is useless:

I will report this problem to the Intel developers, but i want to collect more confirmation.

Yes, I know. I tried the same but I couldn't get the modelines to work. Hope you get some response from the Intel developers.

Thanks, indeed, that does the trick!

An other question: You have remove from your how to the use of the ppa "pvr" for xbmc ? You now suggest to compile from svn? Why exactly if I may ask?

Regarding the refresh problem: I begin to suspect that the Intel chipset just does not support 24p mode. When I read the EDID values I get the following result on my Panasonic 42G20:

I know my tv has more valid modes, last week I tried an Nvidia card and it gave me the following results:

So I know the EDID information can be read from the Panasonic but it looks like the I3 IGP doesn't support it or something.

Yes i suggest compiling. It has two major reasons:

- This ppa contains a modified source for the needs of LiveTV watching.
These modifications could distort results. Would be better to have reproducible results.

- This ppa has packages that interfere with the Ubuntu Xorg update packages.

So i ask if you could use the manual compile we could have consistent results.

I am pretty sure it supports it because on Win7, with xbmc it works. So it is a Linux only problem.

Ok, I've never tried Win7 so I didn't know that.

I just installed the latest DRM Intel Next kernel om 10.01 to see if that helps. It helps in several other areas (alsamixer for example gives a lot more options) but not on the refresh side of things. EDID output is still the same, unfortunately.

Hi,

ok, I compile my xbmc (rev 35584) today.

Trying to decode videos with the vaapi is indeed not really usable for now... I get a lot of stuttering and freezing.
Even in 720p (these were ok using only the cpu i330)...

I tried to use mplayer to see if the problem was only using xbmc, but I can't manage to get the vaapi output to work Confused

...

Code:

typhoe@ns10:~/gpu_accel/mplayer/mplayer-vaapi-20100713/mplayer-vaapi$ vainfo

I get the sound, but no video (as stated in the terminal output).
The vaapi doesn't seem to be known by mplayer... ?

any idea what I missed?

Thank you.
