Are you sure your ION can play 1080i with temporal? What is the source? I
have tried a lot of HD-channels on Thor 0.8W without success and I have to
use bob deinterlace filter or else the hardware drops frames.

Well, video.output.vdpau_enable_inverse_telecine:1 is the one that stoped the 
problem with it freezing and then runing fast
forward. The buffer settings help reduce droped frames as does the chroma 
setting, though it's not a big impact and I see no change
in video quality. Having it deint chroma doesn't seem to have any effect other 
then eat a few more gpu cycles.

 video.output.vdpau_honor_progressive:1 simply turns off deint if you have a 
progressive video. No need to deint was isn't. I do
know that as per other recomendations I had the video buffers up around 1 
and audio down at 5 for awhile and I had more droped
frames with high buffer setting. I could only use bob and the inverse_telecine 
setting is only for spectral.

the main reason why nvidia chooses to deinterlace always even if you use an

be eventually solved (albeit not perfectly) by scaling both fields 
independently.

The main reason is: even with VDPAU there still exists no synchronization 
between stream and video timing.

That means there will be an arbitrary amount of lost/doubled fields with
current VDPAU implementation.

Nvidias workaround now is to deinterlace all content in any case. As a 
result these field losses are (mostly) not directly visible to the human eye.

Ceasing from deinterlacing here would reveal field sequence problems 
(caused by missing stream-synchronization) immediately.

I accept that they prefer always deinterlacing because they didn't
implement proper field parity in their architecture / api /
implementation. But I still think they screwed up. The matrox mga
450/550 cards do field parity pretty well, with a simple api, and in
98% of cases with predictable results and with manageable clock drift
workarounds. Too bad they offer no mpeg2 or h.264 acceleration.

You have the setup I'm looking to get soon.  I want to be able to
transmit video + 7.1 sound over HDMI, do you know if your ION can do
this?  From the screenshots I've seen, the difference between temporal
and spatial-temporal deinterlacing isn't enough to warrant using a
regular size pc (which I have now sitting behind my tv) over the much
much smaller  power not-hungry ION.  Temporal should suit my wants
just fine.

Initially you might think you do, since you'd like to playback bluray

h264 and VC1.



Initially you might think you do, since you'd like to playback bluray
material in the future. But in fact, most of the time you'd be
displaying h.264 from HDTV transmissions, and deinterlacing it, if
it's 1080i. Not all the different GPUs can do the advanced (temporal)
deinterlacing for 1080i material.

In most cases, a 9500gt is the better choice, since it can do just
that, even though it doesn't support VC-1 decoding in hardware, while
a 8400gs can do that, but not deinterlace it.

For a more thorough answer, have a look at the mythtv mailing lists.
  
Well, my ION board with 9400m does temporal deinterlacing of 1080i HDTV 
just fine in xbmc. The question was about the best silent solution and a 
computer with just an Atom and a 9400 requires a lot less cooling than 
something with a discrete graphics card.

did you try the temporal_spatial with 1080i ?

Hi Goga. No, it's not available in xbmc. For some reason xineliboutput 
has never worked as well for HD as xbmc does.

 That's all and well but you should be slapped for that last sentence.

Ah, yes :), here's a couple of non mythtv references;

In my experience, you just have to do deinterlacing in vdpau with
interlaced content, even when displaying on an interlaced display. If
you try to output interlaced material directly, you get ghosting since
the weaved frames are copied to the progressive surface, and the
output resolution might be different than the weave pattern.

It's a shame they didn't get it right when they implemented interlaced
support in this framework.

Spatial termporal deinterlacing is the best one, so get a 9500gt at a
minimum, and forget about vc-1 decoding until there is actually a
working open source bluray player.

 Ämne: [vdr] HD clients for vdr
 
 I recently saw the popcornhour and the HD demo on the popcorn wasn't
 what I expected. It felt like the early adopters of the first DVD
 players that came out. It was more jittery than a Blu-Ray disk on a
 PS3. So now I am wondering, what is the best silent/cheap client out
 there? That actually does 100% smooth playback like a normal DVD
 except at HD resolution/video bandwidth? Are there popcorn
 alternatives? Or is the best now to get a nvidia 9400/9500 to do video
 decode acceleration with a Core 2 Duo type processor of about 3GHz?
 
 What are you opinion?

Hi. My opinion is that nvidia's ION platform with vdpau and XBMC gives the best 
result. The atom's cpu load is 10% playing 1080p h264 so forget the 3GHz core2 
unless you want to play Flash HD movies or other non-vdpau formats.
It's not very cheap yet but you can build a fanless one for €200. For example a 
http://www.cartft.com/catalog/il/1072 together with 2G ram and a pico-psu.

Isn't Flash HD content usually encoded in H.264? That's the case in
youtube, at least, and the clips play fine using vdpau decoding in mplayer.

Just got my ION A up and running as a NAS. Quite a bit of overkill there 
as all I need are the SATA and LAN connectors, plus VGA+KBD to get 
everything set up.


Both fans running at 7v (Case and CPU) and it is pretty quiet. Not sure 
about running the ION A fanless though.



So I will turn that board into my HD client for VDR as soon as I get a 
board more suited to be a NAS.
