Hi All,
Thanks to fritsch and everybody for their hard work.
Big thanks to this thread and ppa:wsnipex/xbmc-fernetmenta-master for improving my PVR experience on Intel NUC D54250WYK
Did not realize how poor the deinterlacing was until after I bought it. Fortunately I found this thread!!.
Using TVHeadend for PVR. vaapi-sse4 for deinterlacing SD of PVR.
Currently I am running xbmc-fernetmenta-master from 30 Jun 2014 or 09 Jul 2014.
They seem to work OK but occasionally there are glitches.... to be expected with Alpha software.
My Question:
Which is the best build to run that incorporates the vaapi-sse4 changes for my PVR usage but does NOT use Helix requirements for the PVR menus yet?
I am running Aeon-Nox skin and with any build past 9 Jul 2014 of xbmc-fernetmenta-master, PVR menus are missing as they need to be in Helix format not Gotham.
Ideally.... I would like Gotham but with vaapi-sse4 changes for my PVR deinterlacing.
Any suggestions?
Thank You

Thanks for the suggestion. I find the lack of fstab etc and not being able to build eg: tvheadend clients from git etc on openelec quite constrictive.
Including running my backup scripts for nightly thumbnail cleanup and thumbnail preloading/populating etc and backing up to my nas.
Things I do as standard from Ubuntu.
How far away is Openelec from Standard Ubuntu?
Am reading up on it now....

The i5 is approximately at 50% CPU playing the 4:2:2 sample with yadif.
Look at the motion of fast moving elements with high-saturation chroma and relatively low luminance - the blue light beams on the wide shots, the foreground audience in the fast tracking shots etc.
The 4:2:0 clip has full 50Hz motion on these elements, the 4:2:2 clip appears to have some odd 25Hz motion artefacts on them, yet other areas of the picture are fine with 50Hz motion (i.e. it isn't a case that the sequence isn't being de-interlaced).
I'm wondering if there is some difference in the way 4:2:2 and 4:2:0 is handled, particularly in chroma terms? It's really odd. I'm running an i7-2600K with Intel drivers.
Could you be more specific on what to look at? Time, region of the screen for example.

I can't find anything in the code which would point in this direction. The only difference between 4:2:2 and 4:2.0 is that 4:2:2 has twice as much chroma samples.

Will try and post times and screen grabs. Not near PC at the moment - probably later this evening.
Have sent PM with links to screen caps and timings.
Checked on two Intel machines. i7-2600K running Ubuntu and the fernetmenta build (temporarily compiled with YADIF not W3FDIF!) and an i5-4250U NUC running OpenElec 4.0.6
I just noticed mjpeg videos stopped working, and the thumbnail picture is kinda decolored, from what my kids told me they stopped working like 20-25 days ago. audio comes out fine, but screen gets jumpy with no video at all.
I just have this XBMC build installed, cant test with regular builds.
i get this error in xbmc.log
ERROR: CDVDVideoCodecFFmpeg::FilterOpen - avfilter_graph_create_filter: src
would debug enable show deeper error logs ?

I hope so - try to upload those.
Edit: Fernet won't reply for the next 10 days - he currently is a long distance away from keyboard - it's summer.

I am quite sure those files won't work with any other xbmc version, too - please provide a sample.
Seems intel has "fixed" - better to say workarounded - one of the hangs we are seeing:
https://bugs.freedesktop.org/show_bug.cgi?id=81447
Please someone that is able to build libva-driver-intel from source could verify this with the sample posted in the above bug.

ah yes, lol, i said it was an old camera
. they all used to play fine in the past, but i dont have any backups of anything older than trusty to test.
https://dl.dropboxusercontent.com/u/2086....42.58.AVI is one that does not play
anyways, if the info doesnt help or its not a minor glitch (aka too hard to fix) dont worry too much
thanks a lot
Juanjo
