[LINUX] HOW-TO use VAAPI HW Acceleration in Intel Core i3 / i5 / i7 integrated GPU

alexb38 Wrote:Any idea?

Not really, since the problem appears to be in your build of XBMC. If I were in your position, I would try to create a clean machine (perhaps a virtual machine or a live CD of a distro) get the latest production drivers and stack and then get the required libraries for building XBMC from standard repositories, not have any XBMC 10 on it at all and see if that 11 build works when vlc is working on that configuration with hardware decoding (this testing cannot be run from a virtual machine but you can run it from a live cd boot).

This is just in case all the testing and downloading earlier resulted in some incompatible libraries being added and to make sure that there is no possibility of any contamination with XBMC 10 files (since the symptoms you have are exactly the same as that of XBMC 10).

I am running into an error when trying to compile XBMC


I started with a fresh ubuntu 10.10 x86 server install and ran through every step including the ones for the minimal install just in case.

I tried
which failed so I tried copying the dependancies out of the README.linux file which is a real pain because instead of a list of packages to install some of the dependancies are in other packages and even if they weren't someone thought it a good idea to add commas after every one.

Anyway I wound up with this

Which seems to have done the trick and XBMC compiled ok. I have not compared the Build-depends in the guide to this list so I don't know all which were missing but I suspect it was the last one in the list at least libyajl-dev.

Also when running make install I got an error /bin/bash: gtk-update-icon-cache: command not found
so I did
which got rid of the error.

try this:

Here we can see that VLC is really using VAAPI :

Code:

libva: libva version 0.32.0
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib64/dri/i965_drv_video.so
libva: va_openDriver() returns 0
[0x1f60f60] avcodec decoder: Using VA API version 0.32 for hardware decoding.

same problem here:
10.10 server, x4500hd with correct vainfo output but when i try to play MKv in xbmc 11pre with VAAPI enabled it crashes back to Desktop.

any idea?

new upstream vaapi for lucid, I thought some of you may want newer drivers

just wanted to check what the status of intel X4500MHD is, still just able to decode mpeg2 right? Starting to doubt intels intentions of actually developing support for h264 under linux.

There is a branch living for libva just for G45 h264 decoding.

http://cgit.freedesktop.org/libva/?h=g45-h264

It is not merged into mainline libva, but you might can try the branch out. I think after git checkout you can change to the g45-h264 branch and build that, instead of the mainline libva.

Hope it helps...

Thanks, tried it, vainfo reports the correct info but xbmc crashes back to console as soon as you try to start playback of a h264 file with vaapi enabled. Works great without it though =)

Hello and thank you for the guide!

I am experiencing stuttering when vaapi is enabled with 1080p mkv files,
runs smooth when i disable vaapi, you have any idea what the issue might be?

I'm running a fresh install of ubuntu 11.04 on a asrock core 100ht-bd --> http://www.asrock.com/nettop/overview.as...20100HT-BD

I have the same issue here. The Problem seems that the GPU Clock
is not adjusted automaticly. On Windows you can see with GPU-Z that
the initial GPU Clock is at 480mhz. After starting xbmc and playing a 1080p file
the Clock speed is at 684mhz. So I went to the Bios and set IGP to 677mhz. After that 1080p plays smooth with vaapi. So I think the GPU Turbo dosn't work with the actual intel drivers.
