just wanted to post to say thanks for this guide. Its been most useful, informative and is so well written it even makes sense to me! And i barely know anything about any of this xorg stuff!

I haven't tried the hw acceleration as i'm not overly bothered (computer in another room so not bothered by fans) however i have applied your xorg.conf fix to get auto refresh rate switching to work running on XBMC Live Dharma. Previously it always set itself to 50hz and even with smooth video it was noticeable.
However now it switches to 24hz (or 23.976hz) and looks much better. Thank you.

On that note i do have a couple of (hopefully) quick questions, apologies if they were answered elsewhere in the thread.
Earlier in the thread you said:

If the refresh is actually set to 23.976 then surely the smoothvideo feature would not be needed, as the refresh rate matches the fps exactly? Or am i missing something?

The OSD while a video is playing still says "refresh: 24". Is this just anomaly with the OSD? I notice that the fps fluctuates between 23.98 and 24.00 which suggests (to me) that smoothvideo is doing its magic.


Not that i've noticed any quality issues so far, just interested

Thanks again,

Afaik intel hardware does not manage 23.976 fps, so its smoothvideo doing its work as you say.

Thanks sandos.

So it's basically the same thing as on Windows then?
I thought that was a driver issue rather than hardware.
Unless they're able to copy large chunks of driver code (I know absolutely nothing about driver coding) then it seems a bit nuts they've implemented the same issue twice!

Oh well, like I said I can't tell with smootvideo magic anyway :-D

Well, anand (of anandtech) says its a hw issue, Im not sure myself.

Yes. Thats the info I know and Intel seems to only correct this "problem" with Ivy Bridge at the end of this year. But with smooth video i think this is not an issue for us. Only for the not so advanced media player applications :-)

Here is the article:

I stand corrected.

I read a bit about it and how sandybridge had the same issue. There was a fix for sandybridge (no idea if it actually worked) and apparently turning off UAC in windows helped. So I assumed it was software.
Doesn't matter, smoothvid@24 looks excellent to me.

Thanks again to you both for the info and fix.

The patch for stuttering has been commited: https://github.com/xbmc/xbmc/commit/76b5...95d571f783

No need for patching because of this anymore. I updated the guide. The refresh rate change patch because of smoothvideo still needed. Not commited yet.

with this tutorial a Zacate plays 1080p smooth under linux!

That's awesome! I was wondering how the new Zacate can handle 1080p content. Great that we have now more options than ION for a great XBMC experience! Thanks for the feedback.

yep, under windows 7 it's even working ootb.

12W idle :-)

This is also not too bad, but with a 2.5Ght Dual core CPU which is waaay faster and has the same power numbers:

The not yet released Intel Core i3-2100T. Check out this review. I think this is also a strong competitor.

yes, but they cost much more! If you only want to stream and to use XBMC, a Zacate is enough i think.

Yep, you are right. It is a great choice.

Is the GUI smooth enough ? Is projectM working with 50-60fps. I have a problem with ProjectM with Intel CPUs. The Opensource driver has a horrible shader performance compared to the Windows Intel drivers.

Gui is very smooth.

projectm always stops compiling with:

Quote:CMake Error at projectM-libvisual/CMakeLists.txt:41 (MESSAGE):
libvisual 0.4 not found! Please visit http://libvisual.sf.net and download
the module.

but libvisual-0.4-0 is already installed.

What OS are you using. On Maverick and Natty it compiles with no problem. Maybe you need a simlink for the .so file.

it's ubuntu Maverick 64-Bit,

what libvisual*.so file does projectm need? - and in what directory? :-)
