Don't be a NUClehead. DIY FTW!

Now stop messin' in my thread all of you!

The truth is i dont see a difference between lac3 and bikubic, so i assume xbmc just shows me bukubik. The truth is also it looks daam good on my 55st50 Panasonic. So?!?

Something is wrong with the development build - even if I choose Bilinear and "normal" Bob (not the VAAPI BOB) for interlacing, I get tearing with the 576i video. On 4.0.2 Bilinear+Bob works fine with or without SW filters enabled.

Jep. That build has the X11 patches we ship in OE since 2 years removed, so you only get "mainline gotham xbmc SDL" which produces that tearing.

Perhaps we get a rebased xbmc build done the next days.

Owners of Q1900-ITX or similar, what temperatures do you get on idle and full load? I've noticed that my Q1900-ITX gets quite hot even in idle - ~61C (after the night of XMBC on, idling) and after an hour of playing blue-ray movie to 80C+. The room temperature is about 21C and there isn't any of airflow going around the room since all windows are closed, however, to comensate that I keep the top lid of case open. The heatsink gets really hot to the touch. The case that I use: http://www.minicase.net/product_E-I5.html
Installed like so: http://i.imgur.com/JCburUF.jpg
Setup: 2x2gb 1.5V ram, 320gb HDD, pci-e wifi card (unused), 60W PSU.

I do not think it should be getting THAT HOT, how about your setups?

In other areas everything works beautifully, the performance is really awesome.

Can you check the HDD temperature? That will rather be too hot. Also 10W devices can get hot, when there is no proper airflow.

Surprisingly the HDD temperature is OK.
sudo hddtemp /dev/sda
/dev/sda: WDC WD3200BPVT-22JJ5T0: 37°C

EDIT: I also tested the Deinterlance method: VAAPI Motion Adaptive on the 576i video as you requested with the advanced config. It worked fine, the FPS stayed at 50 without any noticeable drawbacks.
The 1080i example performs the same as previous with VAAPI BOB. Freezes, drops and so on.

EDIT2: Could someone who has J1900 check what is their Vcore voltage in BIOS?

Not bad for the 576i. I currently prepare another build that has the X11 changes again.

Hi,

Do you know with certainty if J1900 supports SSE? In this Intel data sheet http://ark.intel.com/it/products/78867/I...o-2_42-GHz isn't specified, but here http://www.cpu-upgrade.com/CPUs/Intel/Ce...J1900.html SSE (1,2,3 and 4) are present.

cat /proc/cpuinfo will tell. Last time I looked it was 4.2 - but can easilybe checked.

Here is another test-image: https://dl.dropboxusercontent.com/u/5572...1fdec9.tar - That one should fix at least the tearing.

All fine :-)

My "NUC Alternative Inspired":

Temperature:
12 hours Prime95: Case get a bit warm (40 C I guesss) . Readings --> Motherboard: 48 C, Cores 65-67 C, CPU 58 C.

Our sustem is very close, only differency is you have that HD metal backet over the CPU grill! Only obsavation I can come up with!

Testing this build with the 576i and 1080i samples I can tell that there is HUGE improvement.
The 576i sample plays fine both with the VAAPI BOB and VAAPI Motion Adaptive, just like in the last build
However, when it comes to 1080i now it is watchable and there are no longer 3sec freezes after every second. Now the video plays "somewhat" smoothly without any freezes.

1080i with VAAPI BOB:
Frame rate moves between 48-51 FPS most of the time, sometimes staying stable at 50 FPS during some scenes, there are no noticeable freezes, maaaaaybe a tiny bit of slowdowns for few miliseconds at some scenes, but this is very hard to tell if its the video source 'slowing down' or an actual hardware.

1080i with VAAPI Motion adaptive:
Frame rate moves between 46-52 FPS most of the time, sometimes staying stable at 50 FPS during some scenes, however, unlike VAAPI BOB there are noticeable micro stutters or "frame jumping" At some scenes it feels like there is "shaking" effect or video jumping between frames back and forth for a second, then it goes back to normal again then few seconds later same happens again. I would call this unwatchable.

On top if - I can confirm that the screen tearing is also gone.
