nvidia_vid vidix driver won't scale down to fit in fullscreen

Description

When I watch a video fullscreened with a resolution higher than the screen
resolution using -vo xvidix it is not scaled down to fit the screen. It gets
cropped, and you don't see all of the image. I would really like to see all of
the image.
I originally noticed this problem when I was trying to watch DVD resolution
videos at 640x480, and it was cropping off the subtitles. NO FUN.

I'm running Slackware 8.1, with kernel 2.6.8.1. I have a Nvidia Riva
TNT2/Vanta, and am using Xfree86 4.3.0

According to the users guide for the video card, the overlay "features smooth up
and down scaling with multitap X and Y sub-pixel interpolation", which I think
means it should be able to do this properly.

It does seem to work properly on other video cards, with different drivers (I
tried with a Radeon 7000), so I think it's something wrong with the nvidia_vid
vidix driver.

Owner: changed from alex@… to saschasommer@…

I just compared a few registers when downscaling with -vo directx on windows and
it seems like the overlay engine in the riva128 (should be the same as TNT/TNT2)
can't downscale. When the src image is bigger than the destination a smaller
image gets passed to the overlay engine. This image then gets scalled up.
Interesting enough shrinking the image in the X direction is not possible at
all. Maybe the driver simply does not copy a few lines when doing the
downscaling. It is also possible that the card can do downscaling the same way
as it does the yv12 to yuy2 conversion, but I have really no idea how this
works. The best is probably to shrink the image with -vf scale to be smaller
than the screen resolution. There is currently no way for MPlayer to do this
automatically.

Last comments sounds like this is a wontfix, thus closing. If you have any
information on the hardware how to do downscaling please reopen.
