Mplayer vdpau slow on ubuntu 10.10

I think what may be causing this problem may be these packages
libavcodec52
libavformat52
libpostproc51
libavutil50
libvpx0
xine-vdpau works well with this package installed, mplayer only does give this problems with the packages mentioned above

I did these tests on ubuntu 10:04,

without these package versions that I mentioned above, mplayer works well with the original packages of 10.04

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in mplayer.

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://help.ubuntu.com/community/ReportingBugs.

I can confirm this bug on 10.10 with an nvidia GeForce GTS 250 driver 260.19.06

It also appears in a fairly recent multithreaded version from git://repo.or.cz/mplayer-build.git built with (commit 8a58f701c08d8fbaf8262):
./enable-mt
./init --shallow
make

it has more or less recent versions of libass.a libavcodec.a libavdevice.a libavformat.a libpostproc.a libass.la libavcore.a libavfilter.a libavutil.a libswscale.a statically linked in.
attached the ldd of the resulting mplayer.

I also tried it with the libvdpau1 (0.3-2build1) from lucid without success.

I have to withdraw that confirmation.
For reasons which are a complete mystery to me it works again in repository and git version.
The only changes I did to my system was and placing: vo=xv into my .mplayer/config, watching a few things, reboot and now it works again with -vo vdpau (and change in config reverted)

I can still confirm this bug. I've used both the latest official ubuntu nvidia driver package and the latest one in the X PPA. I've tried Julian's way to 'fix' the issue, but it didn't work at all. Mplayer still isn't faster w/ vdpau than it is with xv output..
I own a Samsung N510 with an nvidia ION LE graphics adapter. The new flash-vdpau acceleration works flawlessly.

from the buglog I conclude that the problem is present in various forks of mplayer. hardware acceleration is provided by the video driver, so I'm reassigning there.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Natty Narwhal. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.
