[Libva] Unfiltered scaling using libva together with mplayer and Intel IEGD 10.3 in rotated mode

[andreas.larsson at multiq.se]

Hey guys!

We're currently trying to use libva together with mplayer to accelerate 
our video playback.

Our platform uses the Intel Atom CPU together with Intel Poulsbo chipset. 
The video driver we use is IEGD 10.3 Beta and our Linux distribution is 
based on Fedora 10.

The problem we see is that when the display is rotated (via options in 
xorg.conf to IEGD) the video playback gets pixelized. It's clearly visible 
that the scale filters have been disabled, i.e. the scaling employs a 
simple nearest neighbour algorithm.

I've pointed out this problem to our premier support at Intel, but they 
sent me to you instead:

"Hello,

Have you contacted the Linux community about this issue? We handle the 
IEGD driver portion of the graphics in this group. Here's a link to the 
VA-API site. There are forums that could be accessed as well as contact 
information at the bottom of the page:

Kind Regards"


Can you guys shine any light on this problem?
