VDPAU and 9500GT
My understanding is that the 9500GT should be powerful enough to run the
Advanced deinterlacers with VDPAU, but that isn't what I observe. If I
try to use the "VDPAU High Quality" or "VDPAU normal" playback profiles,
I get very jerky playback. "VDPAU slim" (Bob deinterlacer) produces
clean playback. Am I mistaken about the power of this card, or is there
some way I can debug why it's not doing what it supposedly can do?

I am using version 185.18.36 of the Nvidia driver on Fedora 10 x86_64,
if that matters.

--Greg

I wonder how much the memory on the card matters. When VDPAU first became
available I recall it was said you needed at least 512MB, I'm not sure if
this is still true, or if the amount of memory makes a difference in what
de-interlacers are supported.

Anybody have recent data on the memory requirements for VDPAU?

I have a 9500GT w/512MB on Fedora 10 32-bit and mythtv 0.22-fixes. I am
currently using NVidia driver version 190.42 and video playback is very
smooth. Video playback has been quite smooth on my system for quite some
time, but I have been keeping current on the NVidia driver versions as they
have been released.

I would concur with the recommendation that you try 190.42.

I had lots of issues with tearing with the 185 drivers. I grabed the the
190 driver from avenards repo. Does anyone know why/when 190 makes it to
Mythbuntu? The 190 drivers are listed on nvidia.com as the official
release.

I tried upgrading the Nvidia driver to 190.42; no joy. Still get jerky
playback (on both H.264 files from the HD-PVR and MPEG2 files from the
HDHomerun) unless I use VDPAU-Slim playback profile.

Not re-read this whole thread but have you gone through the list of
things here http://www.mythtv.org/wiki/Vdpau#Troubleshooting and the
following section on CPU Frequency Scaling (the latter is a common
successful fix)

Probably something dodgy with your videocard, I've seen this before.

Try the vdpau testing program:
http://hftom.free.fr/qvdpautest-0.3.tar.gz

and see what benchmark you get ...

I have two 9500GTs w/ 1GB ram on two different systems on VDPAU high (debian 5 and opensuse 11.2) using 190.42. Both run smoothly, both for H.264 and mpeg2 material.

I would suggest backing up xorg.conf, deleting the original and creating one from scratch using nvidia's utility or by reinstalling 190.42 and letting it create the file (again, from scratch).

Yianni.

Mine only has 512MB, but from what I have read, that should be enough.
Am I wrong? Do I need the 1GB version for the Advanced deinterlacers to
work with VDPAU?

There is more than one type of PCI Express slot that is larger than the x1,
but you probably mean the x16, which is the one usually used for graphics
cards.

I don't think so. As someone previously mentioned, you either have a
bad setting or flaky hardware. I have an 8400GS 512MB and I can run
Temporal 2X on 1080i and Advanced 2X on 480i content.

Correct, it is x16.

I did these things. Probably should have done them one at a time but I
didn't have that much time. It appears that Fedora 10 also uses the
"ridiculous" 95% up_threshold for CPU frequency scaling. I didn't know
what was a reasonable value so I used 50.

The result of all this: VDPAU High Quality still produces jerky
playback. Still can't do Advanced deinterlacing. However, the VDPAU
Normal (Temporal deinterlacing) now does work without jerkiness. So some
improvement, but not as good as it ought to be.

I haven't had a chance to play with the vdpau testing program yet
(http://hftom.free.fr/qvdpautest-0.3.tar.gz) but will hopefully have
time for that over the holiday weekend.

Unfortunately I spoke too soon. I am still getting jerky playback unless
I go to VDPAU Slim profile. I will try to find some time this week to
use the testing/benchmark program

Just so you know 5 minutes will suffice. You just run it and it spits
out results. There isn't much to it.
