gstreamer-vaapi does not work with g45

["Niccolò Belli" <darkbasic@linuxsystems.it>]

Hi,
OS is Gentoo amd64 and my laptop is a Samsung X360 (so gm45).
I'm using x11-libs/libva git (g45-h264 branch) and 
x11-libs/libva-intel-driver bit (g45-h264 branch).

media-libs/gstreamer-0.10.36
media-libs/gst-plugins-base-0.10.36
media-libs/gst-plugins-bad-0.10.23

Using media-plugins/gst-plugins-vaapi git.

Also using:
linux 3.4.0-rt7 (realtime patchset)
libdrm git
x11-drivers/xf86-video-intel-2.19.0 (sna off, vaapi is much slower with 
sna on)
media-libs/mesa-8.0.2
x11-base/xorg-server-1.12.1.902
"SwapbuffersWait" "off"
"vblank_mode" value="0"
kwin desktop effects off

vaapi h264 works flawlessly with mplayer:

mplayer -vo vaapi -va vaapi test.mkv
MPlayer SVN-r33094-4.5.3 (C) 2000-2011 MPlayer Team

Riproduco test.mkv.

Unfortunately it doesn't work with gstreamer-vaapi:

Hope you can help, no one is going to maintain mplayer-vaapi anymore and 
there is no hope for mplayer2-vaapi. I also tried vlc with vaapi but it 
sucks hards (it stutter, you just can't watch a video with vlc and vaapi).

Thanks,
Niccolò
