[LINUX] HOW-TO use VAAPI HW Acceleration on new Intel Sandy Bridge platform

Krautmaster Wrote:is it possible to play interlaced material smooth now having VAAPI enabled...?

Hardware deinterlacing with VAAPI is not yet implemented. With software decode and deinterlacing it plays fine.

There is a huge work going on implementing advanced hardware deinterlacing for vaapi and intel. Check the state here:

Yes, and with <10% CPU load here...

i gonna try now haha thx

okay i build xbmc right now... one problem, i need a xorg.conf for a HD ready tv, 1280x720 or better 1366x768... 25 / 50 hz.

How to?

Maybe someone got one for me... normally it workt without special configs in past.

We will see what happen if i try to use fullHD xorg.conf.


Hm MESA problem:

Quote:configure: error: Package requirements (x11 xt) were not met:

No package 'xt' found

You could try one of these:

I would not use a HD ready TV with a full HD modeline.

thx alanwww1, thanks very much, any ideas on my MESA problem?

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables GLW_CFLAGS
and GLW_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
