If im using nouveau there is no way to use vdpau with it?

Question

Im using ubuntu 12.10 and im using the opensource driver which came reloaded with the distro tried to install the proper driver but I failed, so now im using the opensource driver and its okay, but the only problem is I want to use vdpau coz it accelerate the videos on youtube and smplayer and play it with less cpu usage.

my question is: is there a way to enable vdpau with the opensource driver or do I have to use the proper driver from nvidia ?

As far as I can see we'll have to wait for Debian to fix it.

And there's an unofficial PPA software source you can check out

See http://nouveau.freedesktop.org/wiki/VideoAcceleration/. Depending on your graphics card, it may or may not be supported.
