RE: vaapi-sse4: Deinterlacing Testing - robo989 - 2014-07-27 Thank you fritsch RE: vaapi-sse4: Deinterlacing Testing - robo989 - 2014-07-27 Sorted, sorry vaapi-sse4: Deinterlacing PVR: Helix vs Gotham - ozra - 2014-07-29 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 RE: vaapi-sse4: Deinterlacing Testing - -DDD- - 2014-07-29 What about openelec? RE: vaapi-sse4: Deinterlacing Testing - ozra - 2014-07-29 (2014-07-29, 06:16)-DDD- Wrote: What about openelec? 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.... RE: vaapi-sse4: Deinterlacing Testing - noggin - 2014-07-29 (2014-07-27, 20:23)FernetMenta Wrote: What exactly do I have to look for. Both samples play fine and I can't tell any difference. Tried on i5-4570T Linux, sw multi-threaded decoding and on i7 Windows. 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. RE: vaapi-sse4: Deinterlacing Testing - FernetMenta - 2014-07-29 Could you be more specific on what to look at? Time, region of the screen for example. Quote:I'm wondering if there is some difference in the way 4:2:2 and 4:2:0 is handled 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. RE: vaapi-sse4: Deinterlacing Testing - noggin - 2014-07-29 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 RE: vaapi-sse4: Deinterlacing Testing - Juanjo - 2014-08-02 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 ? Juanjo RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-08-03 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. RE: vaapi-sse4: Deinterlacing Testing - Juanjo - 2014-08-05 ok, i did more testing, some of the files do work.. but i havent found any logic, headers seem the same in both playing and non-playing files.. im posting longs xbmc.log http://paste.ubuntu.com/7956283/ vainfo http://paste.ubuntu.com/7956289/ mesa dpkg http://paste.ubuntu.com/7956296/ id http://paste.ubuntu.com/7956297/ aplay http://paste.ubuntu.com/7956298/ i will try to figure out why some files work and some does not RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-08-05 Quote:20:06:27 T:140663552837376 INFO: ffmpeg[C9198700]: [mpeg4] Video uses a non-standard and wasteful way to store B-frames ('packed B-frames'). Consider using a tool like VirtualDub or avidemux to fix it. 320x240 @ 15 fps? I am quite sure those files won't work with any other xbmc version, too - please provide a sample. RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-08-05 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.
