Amlogic Nougat kernel code is now public so I tried to use it for my LE builds but unfortunately it had some ugly bugs and you'd had to update your device trees so I though I can try porting the most important changes to our current kernel.
A result of this is a new build with Frankenstein kernel to test in OP: 8.0.1b. Please report any regressions in video playback that you observe (known bugs are known!). It's always safe to "update" to 8.0.1a if 8.0.1b does not work well for you, you won't loose your data.
