Prime Instant HD Video in Kodi with inputstream: R.I.P

Google/Amazon changed something : see

In future only SD content can be played :rage:
For HD or better we need Google widevine L1 Certificate devices.
Kodi doesn´t have and won´t get certificate

details here :

Well that’s understandable. It should be the same in Google Chrome or isn’t it?
Even though I have Amazon Prime I rarely use it for video because the Official Amazon App is plain crap. They try to sell their Fire TV devices.
Only way is to use Android but then you can just use their apps too.
