Hi,
I need a help with mencoder+vdpau video encoding?
Yesterday I spent some time to figure it out but without much success.
A search in Google did not produce anything usable to get any result.

I can run without any problem "glxgear" and "tux racer" what indicates
that driver works properly.
When I run "mplayer" with "-vc vdpau" I can see that "mplayer"
attempts to decode but I do not get a video in a window and I get an
error
$ mplayer -vc vdpau movie.mp4

Try appending the scale filter to your filter list,

I can play a movie in "mplayer" and encode video with "mencoder"
without "vdpau".
What am I missing? Where should I look for a solution?
Thanks,
Andy
