Hardware decoding (with licenses) will still work on RPi2/3.
Major issues on RPi2/3 are that the video driver currently has a severe problem (video cuts out and needs reboot), GPU accelerated HEVC decoding and deinterlacing doesn't work (deinterlacing also doesn't work on RPi4).
Therefore we decided to do the initial LE10 releases only for RPi4 - RPi2 will follow later, when the major bugs are ironed out.
Thanks for quick info..I asked as I v seen a post elsewhere that has nothing to do with LE, which made me wonder:
There is no support for hardware accelerated VC-1 or MPEG2 on Raspberry Pi, even on existing devices where codec packs have been purchased.
There is also no deinterlacing for Live TV with hardware acceleration on Raspberry Pi, but we are hoping that support is introduced later at some point with a Kodi 19 point release. This should be less of an issue on Raspberry Pi 4, which should be able to handle deinterlacing in software.
