Thanks... would love to have @Koying's input here on S912 and what kind of 3D decoding to expect. I haven't been keeping up with S9xx happenings as there so many variants and gotchas, but looks like we may have some gems.

It can however decode MVC and output as SBS/TAB 3D.If so, still something with a cheap box being able to do 24p, 4K HDR, full HD audio & decent 3D via Kodi.

Dolby Atmos.
Plus there is no need to manually fiddle with any Kodi settings all the time, its Auto everything. Set and forget.
And that is pretty much running a near bug free Kodi Krypton where all Kodi's core features work including PVR TV viewing clients with proper, reliable high quality deinterlacing.
Even 4K HDR playback on a non HDR 4K 10bit TV looks pretty decent, with no washed out colorspace mapping.

I just tested kszaq build on my s905 minimx, I can't get 3D iso to play in 3D, I don't have time now but in a few hours I'll move the s912 box to my 3D tv and test..

On Nougat, the procedure is:
* Working post process manager for 3D is needed. I remember on some older kernels this was borked; which is why Memphiz added support for SW fallback for 3D -> 2D.
* Enable FP in amports
* Set 3D mode to ON (signalled with AV Infoframe). This is why auto 3D switching doesn't work properly under AML.
* Set fp mode in sysfs (there's a bug here, because AMLogic thinks the VIC mode is the same; so it needs to be reset twice).
* Need proper hints detection so that Kodi sets codec to VFORMAT_H264MVC and pre-header feading works for amcodec.

I believe you need a demuxer for that

probably i still have Kerbers kodi 16 build in the devices internal storage, 3d ISO playback works there.. i dont think i want to remux all my 3D ISOs, i rarely watch 3D anymore anyways ;-(
I am talking about changes to Kodi; not a need to change container type

@ dukester, is this the box you have? Wonder if any/most S912 boxes would work?
yes thats the box im using, the 8gb version, im just running libreelec off SD card and its been really good so far using BT harmony remote paired up as Microsoft Kodi Box
John Wick 2 is a pretty good flick with HDR.
