Is it because HD audio passthrough and auto frame rate switching work in Kodi? Anything else that would be an improvement over 8.1?

Install latest Kodi v 18 stable release, go to settings enable expert mode, in System settings enable audio pass through and see if it lists DTS HD and Dolby Tru HD under pass through options. Also please install any tv live streaming apps like Redbox and see if all channels play smooth. Enable all hardware acceleration settings in Kodi and see if 4K high bitrate videos play without problems.

Thanks for checking. I am not sure if KODI requires a receiver with HD audio decode capabilities connected to show the options. If you already had that then nothing much to rejoice. Hardware acceleration options are usually enabled by default and shows under player settings page. Did Kodi run stable without crashes for watching an whole movie? Other than lack of HD audio support the issues i have in 8.1 KM9 are occasional crashes when playing movies from SMB share, and Amazon prime add on not playing anything although it can show movie list and all. I hope KM9 still has Widevine L1 in pie.

So, I was able to build an Amlogic burn package (.img file) of the latest Android Pie OEM firmware from a partition dump provided by DerKammi. It passes the basic smoke tests, but hasn't yet been fully tested. I did confirm that it installs fine on my old KM9, despite reporting as being based on the newer Amlogic u212 reference board.
KM9-PI-V1.20190220.151755.img
Note that while this is compressed as a ZIP archive to make for a faster download, it's not something you can install from stock recovery or TWRP. You need to unpack and install the IMG file using the latest Amlogic USB Burning Tool or BootcardMaker. I also want to emphasize that the Amlogic SDK 9.0 won't be final until at least the end of this month, so you should consider these Android Pie builds beta quality (at best).

Just tested this new Magendanz's mod on my Mecool KM9 and here is what I have found. First, it is dated, Feb, 20, KM9-PI-V1.20190220.151755. It does use the touch screen version of Android.
Kodi version, 18.1 runs very well, including high bitrate 4k rips.
This firmware, just like the original ATV version, supports Dolby Digital, AND DTS, but NOT the HD audio codecs.
Ethernet and WiFi both work very well. I am testing my high bitrate 4k rip using the 5 Gz band, and there is NO buffering.
As with all of the Amlogic boxes, movies encode with VC-1 codec, struggle with the video stuttering.
Emby and Plex clients refuse to use the ATV version and will only install the touch screen version. The playback of media using these two players, is sub par and not usable.
Netflix as expected plays in DVD quality with stereo only.
YouTube plays 4k videos flawlessly. This is using the 5Gz WiFi connection, and not Ethernet.
At this time, I don't see any difference between Android 8.1 or this Android 9. But perhaps I am missing something.
But as usual, I love Magendanz's mods............ I run his mods on most of my boxes............
Waiting for his ATV version that he will be doing next month.
Edit: For the touch screen version of Android, I use this air mouse remote and it works great. It is an actual air mouse with an RF dongle, for less than $11 USD.

Now that we have an OEM firmware for Android 9 for KM9 (non ATV), am I correct in assuming we will not have any problems building custom ROMs from Amlogic 9.0 ATV SDK? I mean device specific files, drivers and other components can be used from OEM firmware for a fully functional custom ROM? If so its pretty exciting!!

In theory, yes, but it's always a challenge to build the first custom ROM on a new SDK...particularly when the SDK isn't yet final. They tend to make subtle changes to build tools without telling us, and we don't have access to SDK downloads directly from Amlogic. There's an inherent lag between when the OEMs start work and when we can.
