Windows Server 2003 and Windows XP/2000: MMCSS is not available.

See: Multimedia Class Scheduler Service (Windows)

So it is >= vista

If you check the patch I bet the code is taking care of that (loading the method from a DLL instead of directly linking against it).

Correct - it tries to load "avrt.dll" - if it fails then the MMCSS functions aren't called.

evr.log should say "Successfully loaded AVRT dll" if it's supported, followed by some "AvSetMmThreadPriority" entries in the log.

The new dll works tremendously well here on 1:2 material. That should be integrated into the svn. Thank you very much.

and the sample buffers have been increased from 5 to 10 - plus a few other minor changes. Note - early feedback is showing problems on low-end GPUs at least...

1920x1080x32*10 / 1024 / 8 which is approx 80MB. On top of that MP textures and video decoding memory requirement + AERO. I'm quite sure that the GPU memory usage is causing at least some of the trouble low end GPU users are seeing. It would be better to base the amount of frames to the available / free GPU memory. Some care needs to be taken since it could be that Vista / Windows 7 report the virtual GPU memory as well (that is something we really don't want to use with video playback ).

@ Tourettes, can you estimate how much memory is required on a GPU for the things you mention? Is 512mb enough? Or is this clearly insufficient.?

@ Owlsroost, what is your thouth about the thing I am seeing.... Described >>here<<. FYI, this morning I tried V12. No change on the result...

Thank guys for the focus to improve things even further

You need a more powerful video card....all the symptoms point to that being the problem....

v12 and v13 works equally well on my Radeon 5450 with 512 MB RAM. Even the short stutter at the beginning after switching to a 1080i HDTV-channel (ServusTV HD) is gone now. (not using Reclock)

Hi Edterbak - I am having similar issues to you.

I have a HD4550 with 512MB memory.

I have reinstalled Windows 64bit Ultimate and reinstalled RC4. It does run a bit more smoothly, but the RC4 dshowhelper is terrible for me.

V2 and V4 of Owlsroost are best with V2 being slightly better. I am still getting slight judder on 24hz panning shots on x264 files. I cannot say for sure but with advice given on this thread, I think I have got this smoothed out with ReClock.

However, my problematic 25hz xvids are still hopelessly jerky and reclock makes little difference. I have tried to change the 'Deinterlacing' option if ffdshow to double up the frames and I think this is helping, but far from ideal.

I really am wondering if my graphics card is suffiecient or not. I play back on a Panasonic 1080p plasma tv.

Can someone confirm - I have vector adaptive set in CCC, but where is the vsync setting that edterbak mentions?

I appreciate everyone's guidance. I will try the new dlls tonight.

Arrghh.. thats not what I wanted to hear.. Ghehehe... But if it is so... it is soo
Thanks for the response!

@ Tourettes, You were right in your diagnose (different thread). I am convinced now as well. I needed a little bit extra convicing befor I spend more money again... (my wife isnt going to like it ) thanks for the anwsers in any case. Much appreciated!

@ Jet70, I have a HD4350 with 512MB. In general I have no issues with playback mediafiles. Only 1080i files judder.
I use SAF5.0 latest *unlocked*. I recommend you use ATI catalyst 10.4+ because of the DXVA reference frames limitation in mediafiles with >5.1high profiles.
The V-sync settings you can find in CCC > 3D menu > All settings. If you scroll down you have a slider with V-sync settings. I have it set all the way to the right (always on), but havent noticed a big change if its all the way to the left. Does this help?

 

[jet70]

I'm using 10.5 ATI - I will try the Vsync setting when I get home and maybe try SAF 5.0 - at the moment I am SAF 4.0 unlocked.

What do you use as your audio decoder for xvid/mpeg?

I really am at a loss ast to why I get so much judder with certain xvid files but will experiment tonight and post back on the forum - thanks.
