Hi
Christoph !<div><br></div><div>For the stuttering problem it is cause by lack of shader horse power to use HQ upsacling AND deinterlacing together.</div><div>Please try to set the upscaler from auto to "bilinear" or even "nearest" at the worst case.</div>
<div>Also if you are using xbmc in a composited environment please turn off all compositing or even try to run xbmc in a separate Xsession.</div><div><br></div><div>If that does not help, you probably will never have it working stutter-free with Clarkdale.</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>
<br>
I know what is the problem. For some reason, the native pixel format<br>
for MPEG-2 decoding on Clarkdale is I420, however the input pixel format<br>
of deinterlacing is NV12 in the driver, so the driver doesn't support<br>
deinterlacing for MPEG-2 on Clardale. We will try to fix this issue but<br>
don't expect it too soon.<br>
<br>
BTW you can send all VAAPI related mail to <a href="mailto:libva@lists.freedesktop.org">libva@lists.freedesktop.org</a><br>
as well.<br>
<br>
Thanks<br>
