Hi Christian, All,

thank you for fast reply

i'm using gentoo and i merged the vdpau backend (actually i tought it
was only for nvidia cards) but it seems not really working

vainfo
libva: VA-API version 0.32.0
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib64/va/drivers/r600_drv_video.so
libva: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

maybe i need to symlink that to the r600 to vdpau shared object.

I'll test later and report when i'm at home.
