VDPAU in mplayer shows no CPU difference on 9600M GT
I have a HP dv5t laptop with a Nvidia 9600M GT. I have installed the 180.44 driver. In mplayer, I've switched to the vdpau video output driver, but the CPU is still hovering at around 35-40%, which is the same cpu usage as under xv. I've even tried switching to ffh264vdpau as the video codec, but that caused the video to not play at all. Mplayer complains that the video_out device is incompatible with this codec.
Is the 9600M GT supported by VDPAU at all?
