[vdr] vdpau experience

So far getting vdpau to work on Gentoo wasn't that difficult.

Overlay vdr-xine was used and then emerged xine-lib-1.2 to bring the
library up to speed. After that I pulled vdr-xineliboutput from cvs.
Compiled and it worked great especially deinterlacing! Only jaw
dropping experience there.

I have before got accustomed to using the cropping feature from
vdr-xineliboutput plugin. Crop converts a 4:3 input to 16:9 format. In
the README it states:

VDPAU

  All video scaling, cropping, and postprocessing options must be disabled
  if the VDPAU output device is used.
  De-interlacing can be enabled with command-line option --post tvtime:
  Examples:
    vdr-sxfe --video vdpau --post tvtime:method=use_vo_driver
    vdr -P"xineliboutput --video=vdpau --post=tvtime:method=use_vo_driver"

In the mean time, I have seen some patches floating on german speaking
forums on how to get cropping feature to work with vdpau.

http://vdr-portal.de/board/thread.php?threadid=86804 Does seem to give
the impression that it is doable. But I'm having trouble translating
that into.. well meaning full non-german speaking end-user noob.

Is there anybody that could explain where these patches fit in?

I use vdr-xineliboutput, pulled in from cvs and tried to apply the
patch   xineliboutput-1.0.4-vdpau-support-v8.diff and failed. perhaps
command line incorrect? any examples?

I don't know how to patch xine-lib either, Gentoo pulls in
xine-lib-1.2 from http://hg.debian.org/hg/xine-lib/xine-lib-1.2/
The first line in the diff file for xine-lib is for vdr.h, which I
cannot find. The find utility only returns

./xine-lib-1.2/.hg/store/data/include/xine/input__vdr.h.i
./xine-lib-1.2/.hg/store/data/include/xine/vdr.h.i
./xine-lib-1.2/.hg/store/data/src/vdr/combined__vdr.h.i
./xine-lib-1.2/.hg/store/data/src/vdr/input__vdr.h.i
./xine-lib-1.2/.hg/store/data/src/vdr/post__vdr.h.i

So I'm stuck, any other Gentoo users here that got those patches working?

Thanks,
Theunis
