+--- Thread: Bay Trail-D motherboards (/showthread.php?tid=184930)
RE: Bay Trail-D motherboards - fritsch - 2014-08-10
VPP drivers are reworked. Gwenoule mailed us two days ago that he is redoing the VPP functionality. It looks like we get forward + backwards reference frame this time. So there is a good chance we will end up with HQ deinterlacing - but yeah for the Baytrail with the f**uped GPU and the 4EUs I don't see a chance yet - happy to be proven wrong.

That's one of the benefits of the Haswell Celeron 2955U in the Chromebox and Gigabyte Brix (and if you don't watch 24p stuff, the Ivy Bridge Celeron 1007U and 1037U in other boxes). They have the CPU power to do YADIF 2x de-interlace of 1080/50i, which is significantly better than Bob. It's a pity that Intel's Linux drivers are so poor in de-interlacing terms (aka VPP)
Isn't the J1900 actually (slightly) faster than the 1007U and 1037U in terms of CPU power?
Obviously the GPU is rubbish.

Can anyone recommend a replacement CPU fan for the J1900 as the stock one is very noisy.

My j1900 doesn't have any fans what motherboard do you have?

It's from this desktop PC http://www.acer.co.uk/ac/en/GB/content/model-datasheet/DT.SULEK.004
The fan you see on top of the CPU heatsink is a
SUNON® DR MAGLev Axial Fan 12V DC 40 x 40 x 10mm ME40101V1-000U-G99, this one http://www.digikey.com/product-search/en?mpart=ME40101V1-000U-G99&vendor=259
I don't really want to replace the fan with the same one, I was looking for a better compatible fan for a quieter solution...
Any help would be appreciated...

I've never brought a silent 40mm fan but maybe one idea would be to get a reducer (80mm to 40mm)and get a 80mm fan which should run slower than the 40mm one . that's if you have room, if not I think a good internet search should turn up the quietest 40mm fan

Cheers, did a quick search for a 40mm - 80mm fan adapters but couldn't find any, plenty of 40mm - 60mm ones, will have to open the case and see if space will not be a problem so will decide which fan and adapter to get to replace the stock one...

Guys to all of you that experience problem with deinterlacing this huppens with windows also? I wanna buy a j1900 that's why I'm asking
RE: Bay Trail-D motherboards - -DDD- - 2014-08-11
Seems to work with windows: http://www.vdr-portal.de/board18-vdr-hardware/board84-allgemein/p1199749-review-asrock-q1900m-intel-bay-trail-d/#post1199749

I suspect the Windows drivers allow for better-than-Bob de-interlacing in hardware.

What do you think about it?
[UPDATE]
The so-called "UHD-AVC playback: XBMC OpenELEC 4.1.3 (choppy) versus MPC-BE (smooth)" youtube demo were replaced with an
OE with Dual Channel Memory Mode vs OE with Single Channel Memory Mode vs MPC-BE with Single Channel Memory Mode (demo, 76MB)

Debug Log and screenshots of the OpenELEC settings under Video -> Acceleration, please.
RE: Bay Trail-D motherboards - fritsch - 2014-08-12
And a codec info would be nice inlcuding mediainfo - thx.
