Further testing shows that with Android, all videos are decrypted properly. See Xiaomi 4K HDR 'Mi Box' (Android TV set-top box) where wrxtasy describes his solution. It works for me with the wetek hub and Android M.With LE, only videos that are using an older encryption can be decrypted. I did not notice it at first, because the series I am binging on currently all use the older encryption.
Do we know which videos use the older encryption? I am currently using LibreELEC 8.0.1 Kodi 17.1 on Raspberry Pi 3 with Amazon VOD installed and set-up, and ran the bash line code to install the widevine DRM thing. It installed correctly but I still cannot watch the content. Any ideas or work around known right now? Does anyone else have this still working?? I'm in the US by the way.
