Been away from the forums for a while and been a bit busy over the S.Hemisphere Holiday period. Been doing some testing as well.
Previously users have been wary of the S912 with it's ARM Mali T820 GPU due to uncertainty with properly implemented Linux Mali GPU drivers which will be definitely be needed for Kodi v19 M. Which is at least a year away.
As chewitt has already demonstrated in previous posts, work is already underway to add such stable T820 GPU driver support for Kodi v19 rendering.
The S912 always had a problem with upcoming Inputstream-Adaptive - Linux / CoreELEC Kodi Leia - ffmpeg (CPU) h.264 decoding and rendering - needed for Leia Netflix Addon streaming. In fact you could not even ffmpeg decode and stream 720p
The Kodi Leia rending performance issue has been hunted down by @fritsch and @peak3d just today and there is now a noticeable increase in ffmpeg decoding and rendering performance on ARM platforms. 720p Netflix now works smoothly with Kodi Leia on the S912.
See the Kodi Leia PR HERE
In fact I can decode and playback 1080p h264 Bluray Rips and (low bitrate) 1080p 10bit HEVC - using CPU software decoding alone on the S912 - MINIX U9.
Be aware I'm using newer libhybris OpenGLES 2.0/3.2 - which I hope to include in future LE / CE versions - they increase rendering performance as well, especially with GLES 3.2 in Android 6.0 onwards.
The GPU Overclocked S912 is now equal quickest S9xx platform I use, rivalling the SDR only Overclocked ODROID C2.
Oh and the S912, Kodi dirtyregions workaround for S912 Subtitle stuttering will no longer be needed for Linux Kodi Leia with the above PR.
Details about that HERE
