<div class="Ih2E3d">> Am I mistaken? What am I missing, if anything?<br>
<br>
</div>OK - so I've been spending far too much time playing with VDPAU today<br>
to resist responding :)<br>
<br>
As I type I've got mythtv playing live tv using vdpau for playback.<br>
Double rate temporal deinterlacer, standard def MPEG2 source, (mostly)<br>
working osd, core2due 2.4gz, 8800GT and 1GB ram. Current utilisation<br>
hovers at around 1-2%.<br>
<br>
Switch to the 1080i/h264 channel (think high bitrate) - 1-2%.<br>
<br>
Switch to an old BBC HD h264 recording (again 1080i/high bitrate) - load 1-2%.<br>
<br>
No tearing, vertical sync seems to work 'out of the box' and<br>
deinterlacing quality is reasonable (though the implementation is<br>
simple and some further work could improve it).<br>
<br>
The main downside at the moment is picture quality (and the same<br>
issues apply to mplayer - so appear to be related to the state of the<br>
api/driver):-<br>
<br>
- all my h264 streams break up intermittently. I think nvidia have<br>
acknowledged that higher profile streams still have issues. Otherwise<br>
quality is very good.<br>
- all my mpeg2 streams and recordings exhibit some form of vertical<br>
'blockiness'. It varies by source and I even see it on the nvidia<br>
'reference' clips.<br>
<br>
All told, a pretty impressive start from nvidia - but it needs work.<br>
<br>

</font></blockquote></div><br>I don't wish to take this thread OT but is this VDPAU included in newer drivers? I have an 8800GT and would love to see what the fuss is all about (as if Mark doesn't make a compelling case as it is!). I am using 177.80 drivers from nvidia's site. I saw a post on reddit a few days back linking to the VDPAU section of <a href="http://download.nvidia.com">download.nvidia.com</a> but I did not see any source or binary packages, just oodles of technical jargon that had me baffled lol.<br>
