The developer who was contracted to work on the decoder went down the rabbit hole of persuing a stateless implementation. This would be awesome to have since it means no closed-source firmware blobs, but it turns out Amlogic doesn't expose a bunch of low-level stuff needed and this was not discovered until he'd already burned through 4-5 months worth of funding. There is still a strong commitment for further work (starting over with a stateful implementation) but right now the war-chest is lacking funds and we'll need to wait a while until business profits refil the coffers. It's annoying, but c'est la vie, this kind of setback does happen.
I wouldn't expect any real-world changes from LE11 images to LE12; ffmpeg and Kodi evolved a little but the underlying kernel is currently the same and that's really what dicates how things behave. I'm working up enthusiasm for a bump to Linux 6.5.x but most of the development in the kernel since Linux 6.1.x is refactoring (rearranging deckchairs on the titanic) and the early stages of adding support for new hardware generations (but nothing we'll be able to use).
I have no interest in aarch64 LE11 images. You can try to create them yourself, but there were build issues when LE12 first switched so you'll probably hit issues and need to backport things. IMHO it's not worth the effort. And LE12 nightlies will eventually turn into LE12 release images .. but with the same LARGE BOLD TEXT warnings on state and usability (nothing has really changed). The number of people using the AMLGX images continues to increase with time, but the image won't flourish without better decoders, and chasing user numbers has never really been a personal motivation or team objective.
