Fixes

• Video playback stuttering when using external Subtitles on S912 devices

Notes

• 444,10bit settings should only be used on a HDMI 2.0 connected 4K 10bit capable display.
  Otherwise expect a permanent black screen.
• Update compatible with kszaq LibreELEC releases. Not compatible with CoreELEC.

Tips

• Suggestion is to leave the Kodi GUI at 1080p50/60Hz so a 4K TV can upscale all non 4K video.
• AML LE Kodi autoswitches 1080p <<-->> 4K anyway when playing back actual 4K video.

Known Bugs

• There is no 4:2:2 Chroma Subsampling support for those with 4:2:2 only projectors.
