In ticket #5232 libvdpau-0.8 is specified as a new version. I can build it

How do I know it it's being used and if it's working properly?
Anyone know?

for "being used" -
ISTR that I saw messages about its omission (probably on stderr)
when I started xine (ui) on an AMD box. From past contributions, I
think it might get used on intel graphics as well as nouveau, but I
cannot confirm that.
(and therefore, "I have no idea" for the "working properly"
question.)
I got that error too. Installed libvdpau-0.8 and re-ran xine. Now I get:
Failed to open VDPAU backend libvdpau_i965.so: cannot open shared
object file: No such file or directory
vo_vdpau: Can't create vdp device : No vdpau implementation.
I did find this in the ChangeLog for the Intel driver:
"Since 2010, DRI2 supports multiple driver names. That was added to ease
selection of appropriate driver by libvdpau. As for today, intel driver
support only DRI2DriverDRI (== 0), but not DRI2DriverVDPAU (== 1).
Although there is no any hardware-specific VDPAU driver for intel video
adapters at the moment, it would be easier to use generic drivers like
libvdpau-va-gl by creating symlink named libvdpau_i965.so.1. That way
appropriate driver will be selected in run time automatically:
libvdpau_i965.so.1 on i965 equipped machines, and libvdpau_nvidia.so.1
on nvidia equipped ones.
[ickle: Whilst I think this is a workaround for a brainfart in libvdpau
that it defaults to libvdpau_nvidia.so rather than first to
libdvpau_${DRI2DriverDRI} and then to a hardcoded libvdpau_backend.so,
I have no better solution, and this does seem in accordance with the
spec.]"
I don't know how to interpret that.
