Verified media path cannot be verified

[aky-01]

Hi,

I get this VMP error on Linux ARM and Windows x86_64 devices from https://wv-keyos.licensekeyserver.com/ server.
Playback working only on Linux x86_64 and Android devices.
Tested in Leia 18.9 with IA 2.4.6 and Matrix 19.0 with IA 2.6.7 with same results.

Log from Raspberry Pi 2 LibreELEC:

This has been reported here also: #593

Related issues:

• Unable to play DRM protected content on ARM devices add-ons/plugin.video.viervijfzes#69
• Replay [BE] Rtbf Catch-up-TV-and-More/plugin.video.catchuptvandmore#402

My best guess is that wv-keyos.licensekeyserver.com enforces VMP for all platforms, but they have an exception for Linux x86_64, so you can watch from a Chrome or Firefox on a Linux system. It seems they don't have an exception for Linux ARM.

I assume that on Android, the VMP works, since IA uses the system implementation of widevine, on Windows, it doesn't work, since we have no VMP there.
