Lima woke from slumber about 4-5 months ago and started showing progress and we've been engaged with Yuq since - the video you've posted was created this morning by LibreELEC team member koenkooi and an equivalent LE image is my task this evening. We've also been engaged with the panfrost developers for some time and recently persuaded a couple of them to accept S912 boards so development can be done on a modern mainline kernel instead of Chromebooks that require an ageing Rockchip 4.4 codebase. We are being our usual helpful and supportive selves and Kodi support is seen as a worthwhile panfrost objective. I'm confident panfrost will be the missing piece of the long-term jigsaw puzzle we need for S912 support, but things are still at an early stage and it will be some time before panfrost code is in a mature state that's sensible to use (we did get it to show bits of the Kodi GUI tho!). I'd guess another six months is needed - the midgard/bifrost chips are mind-bogglingly more complicated (and completely different) compared to the older utgdard chips.
Thank you for a detailed reply, chewitt! Can you comment on the state of Maxime Jourdan's work on Amlogic video codec? Can we expect fullfledged open source video decoder for modern formats like HEVC 10-bit in not so distant future? I'm sorry to bother you, but this information is really scarce on the Internet.
