I have a Palit 9500GT Super+ 1GB, (which has DDR2), and am unable to use vdpau with it.
My m/b has a 750a SLI chipset, and using the onboard gpu, I am able to get vdpau working, though not smoothly.
I am using the 185.19 drivers.
With the command
mplayer The\ Simpsons.mpg -vo vdpau -vc ffh264 > ffh264.txt
I see a green screen, then mplayer crashes.
mplayer The\ Simpsons.mpg -vo vdpau -vc ffh264vdpau > ffh264vdpau.txt
gives no mplayer window, and just prints error messages.
I had the following set in my shell.
I also have NVRM: Xid errors in my syslog.
Is there something I am overlooking here?
