nvidia 8200 IGP + VDPAU no luck

Hi,

I've read a number of reports that seem to confirm that the 8200 IGP is
sufficient for VDPAU decoding of HD h.264 material, such as that
produced by the HD-PVR.

I've had no luck with mine.

When I play back 720p the video is smooth for about two or three
seconds, then starts to stuttering and dropping frames.

If I put a dedicated card in (9500 GT), playback is as smooth as butter.

Is there any special build-time configuration that will help? What
about settings in the software, such as deinterlacer (shouldn't
matter--720p), etc?

My configuration:
I've got a SFF Acer machine with an 8200 IGP, Athlon LE-1600 and the
maximum memory allocated to the GPU (512MB I think).
I'm running trunk revision 20949
I'm running on Mythbuntu 9.04 with the default mythtv packages removed.
Nvidia drivers are 185.18.14

Thanks for any tips

Zach

I found the only way to get smooth playback with my 8200 IGP was to
set the scaling_governor to performance or disable cpu frequency
scaling altogether. For some reason the video would stutter when the
cpu scaled down to 1GHz even though the cpu usage would stay below
10%.

I know that Jean-Yves (who backported vdpau to 0.21-fixes) had trouble
with 185.x nvidia drivers and recommended going back to 180.x. Mind
you that was on 0.21-fixes with the backport. Whether that applies to
trunk, I do not know. Heres the post anyway:

According to the mythtv wiki you'll have to adjust the cpuspeed daemon
frequencies:
http://www.mythtv.org/wiki/VDPAU#Troubleshooting

Doing so did solve my issues with choppy playback.

This is still the case, should you use trunk or 0.21-fixes, I can
consistently crash X with 185.18.14 no matter if you use mplayer or
mythtv

190.16 has worked okay for me so far ; provided you disable OpenGL
V-Sync otherwise you get xcb errors which kills mythtv.

Okay, I'll try this. If it works, is there a way to set this
permanently? Can the "cpuspeed daemon" be disabled. I have no
services. Echoing values into /sys from rc.local seems like a hack.

Thanks for the tips.

Okay a couple of tips indicating 185.x might be a problem. I'll roll
back to 180.x. Thanks.

Its a bit of a misnomer saying 'cpuspeed daemon' on any modern system,
as frequency scaling is generally done entirely in the kernel, without
any userspace daemon. There *is* a cpuspeed daemon, but only a select
few systems need this anymore. In-kernel frequency scaling is indeed
controlled by echoing stuff into /sys, or by using cpufrequtils.

I didn't have any problems with instability under 185.18.14, and have
been using it almost two months with MythTV. However I did experience
quite a lot of screen tearing with my Asus M3N78-VM (nVidia 8200 IGP)
combined FE/BE I tried everything to resolve it (including 180.60,
which was worse), and had pretty much given up.

However, I installed the nVidia 190.16 beta driver on Tuesday when it
came out. It cleared the screen tearing right up, as well as other
artifacts I was seeing (e.g., sepia ghosting on black/white
recordings). This is with 720p recordings from an HD-PVR on a 1080p
display over HDMI audio+video). Running current trunk with kubuntu 9.10
alpha. (If you're trying to get a new system going under ubuntu
9.04.... I suggest also moving to 9.10 at this point. The 190.16
driver also installs easily with the current 2.6.31-3 kernel.)

I recommend that anyone with an 8200 IGP give the 190.16 driver a try.

Phil,

I'll give give 190.x a try. I changed my cpu scaling to performance
which cleared things right up. However I am getting the tearing, so
maybe the newer drivers will help that.

I'm also curious about your audio over HDMI, which I'll ask about in a
separate thread.

Thanks

I use 180.x w/ the 8200igp; without openGL sync I had tearing.
Tunning on opengl sync solved that for me at least. Oh, and yes you
need to turn up the CPU for anything to work properly.

I updated to 190.18 drivers and tearing went away. Still getting a
little audio stuttering. It's annoying but tolerable.

Thanks for the tip.

Hi I need to update the wiki you should just need to modify the
/etc/sysconfig/cpuspeed configuration file and modify the following line:

MIN_SPEED=1800000
