Hi,
I've been doing some tests, (before I try jumbo frames), and I've notice that while playing a DVD (VOB) from my NAS to my Core/Hybrid, or to a MD, xine has been running at 79-80% CPU.
This is with both hardware acceleration & De-interlace quality set to vdpau with video card defaulted to GeForce.
Picture looks great but it seems strange that CPU % is so high.
I've tried stuff but with little success at reducing CPU % (which I didn't think would be that high in the first place).
Am I'm wrong thinking this is an issue?
Cheers

Hi,
Found this post...
http://forum.linuxmce.org/index.php?topic=13332.0
...have changed Shared Memory Size on Core/Hybrid mobo from 256 to 512.
No luck.
unfortunately, you did not specify what vid card you are running. Some are better able to utilize vdpau than others. I ran a 1st gen atom based board with nvidia graphics chipset, and never had a cpu load that high driving a 1080p display.
Hi,
I've been testing this on my Core and it has an onboard Nvidia GeForce 8200 with a Nvidia GeForce 8500 GT PCI Express.
I'm not using SLI because I don't have enough memory on board (need at least 2Gig).
The main adapter is the 8500 GT.
The MD is an Acer 330 ION 9rev b1)
I haven't looked at the second MD performance yet but if I remember correctly it's a Nvidia 9500 card.
Cheers
Don't use the 8xxx series cards with VDPAU...the 8300 does not support it correctly, and the 8500 is the first gen, which doesn't do all that much to help you.

OK,
So take vdpau out of webadmin settings. Leave GeForce as video card?
What would recommend for acceleration? Stick with xv? Interlacing?
Thanks.
That, or... get a newer video card, perhaps? :)

Hi,
I guess that would mean change out the video card on my Core/Hybrid, scrap and replace my ACER 330 ION and my AOpen DE7000.
It doesn't matter how deep my pockets are, when I get to the bottom there's still no money.
* heavy hmm *
The ION should not have a problem.
Hi,
Unfortunately, my ION is running at 80% with xine-player (see earlier reply) which is why I am "what the heck" because I can't see why I would have an issue with the Core/Hybrid in the first place because it has the "POWER" (desktop unit, faster CPU, etc., etc.).
I'm also at a loss why the ION and DE7000 can setup 9000 mtu speeds and the Core/Hybrid (both ethX) craps out above 7000 MTU. I tried 8000 as the next setting but it was a no go. (Does this have something to do with having to swap network interfaces?.)
So my next head scratcher was what happens with iperf and transmission speeds over the network @ various MTU setttings using a test VOB (the same VOB, over and over and over and over) from my NAS to the Core/Hybrid, Acer 330 ION and DE7000!
Did you try without deinterlacing?
Hi posde,
vdpau with no interlacing, xine-player = 80% CPU via top
xv with no interlacing, xine-player = 20% CPU via top
opengl with no interlacing, xine-player = 40% CPU via top
System was rebooted after each change.
Mobo = ECS GF8200A Black Series, 2 Gig RAM, AMD 5200+ x2
That's not the ION is it?!
Hi posde,
Sorry I took so long to reply but I installed the April 16 28950 snap and had to generate the MD.
The ION results are as follows...
Standard video card - xv acceleration - no interlacing = 20% CPU via top
" - opengl acceleration - " = 35 %
GeForce video card - xv accelaeration - " = 20%
" - opengl acceleration - " = 35%
" - vdpau acceleration - " = 85+%
" - " - Vdpau interlacing = 85+%
ION MD rebooted each time after changes.
Same VOB played each time.
For some reason Picture Viewer was running @ 100% on vdpau/vdpau. I rebooted Core/Hybrid - NAS & ION MD.
It's OK now.
Cheers
/me had disabled the picture viewer on the ION, and also chose the UI2 masked instead of alpha (don't know which one you have)
Hi posde,
I'm using second choice - medium.
It wasn't Photo_Screen_Saver that was peg at 100% but Picture_Viewer.
Or are they part of the same mechanism?
Thanks.
Not sure, but I would disable it as well
Hi,
I've been working @ this. I have my CPU cycles way down.
When I get some time, (got a new [24/7] job), I have a couple of tests to nail what I did wrong, or what others might do wrong.
[Core/MD/kernel version/nvidia version drivers (Core/MD's), nouveau drivers, ubuntu-restricted-extras, dist-upgrade, blah, blah, blah.
My ION has good % now without disabling stuff.
Cheers
two good news: A new job, and getting CPU cycles down! Congrats on both :)
