but must have got something wrong as I seem to get rendering ("o" shows whats going on but the display is black) and audio but no display with all VAAPi methods: I will reinstall from scratch as its probably my fault. To jump over local issues I:
Tried Openelec image
Latest ??)

Hardware: Intel Baytrail Celeron j1900 Gigabyte -Brix 4Gb single channel and HDMI connected to 1080P display.
Bilinear
1080i50 (serverus sample) with MADI / MCDI deinterlacing on a 1080p display: no skips or drops, skips when displaying "o"
1080i50 (BBC News sample) with MCDI deinterlacing on a 1080p display: no skips or drops, skips when displaying "o", tearing/artifacts on ticker.
1080i50 (BBC News sample) with MADI deinterlacing on a 1080p display: no skips or drops, skips when displaying "o", no noticable tearing/artifacts on ticker.
576i50 with MADI / MCDI deinterlacing scaling to 1080p: no drops or skips, smooth scrolling but obvious artifacts on both MCDI and MADI
4kp30 with MADI / MCDI scaling to 1080p: perfect
4kp60 with MADI / MCDI scaling to 1080p: perfect but occasional ( not noticeable) skips when playing, skips when "o" is pressed to give results or overlay displayed
Lanczos3
576i50 & 720p50 Upscale & 4k downscale skip a lot and not fluid (MADI / MCDI / VAAPI-BOB) - BoB + Lanczos3 does not skip until "o" is pressed.
couple of questions. I read a large number of the 1900 odd posts , but the story is so fast changing due to the excellent work going on, it is now hard to follow.
I came to Kodi from mythtv as a frontend, ( for predominately 576i50 or 1080i50 off air recordings ), as I was "upgrading" from my old Acer revo to a shiny new nuc like BRIX. Mythtv has virtually no usable support for VAAPI and I had heard good things about kodi/openelec as a frontend.
post #1 states "If you are running a Baytrail NUC or a 847 Celeron NUC or comparable - choose Scaling: Bilinear and Deinterlace-Method: BOB"
"VAAPI-MCDI is not available on a Baytrail as this is an IVB based chip." [is post 1 just very out of date ? ]
I was so disappointed with the j1900 display quality after ion. I was about to replace my new j1900 with a 2975U, or possibly a 3050 nuc, hoping to get back to decent (ion) video quality, but now am confused whether the video quality is the same on baytrail and on haswell and braswell, with the current state of this code. My use case is predominantly UK HD Freesat, so 1080i50.
The story was quite clear ( buy a chromebox/2955u/2957u) before you inconveniently made the code so much better :-) :-)
I know this is not the " what hardware thread" but a summary of current hardware dependent capabilities would be really useful in the first post.
