Hallo all,

i trying to test current libva, but have problem to play H264 video.
If i'm correct this board ( intel DG45ID (GMA4500HD), Vendor: 0x8086,
Device: 0x2e22, Revision: 0x03 (A3)) should support it, mpeg2 videos are
played correctly.

mplayer return this error:
libavformat file format detected.

i use libva from git master, ( last commit e9c00fc43e "Fix vaGetImage()
bounds checking code."), libdrm 2.4.21 from ubuntu ppa. And ubuntu
kernel 2.6.35-7-generic.
