### Description
Trying to play a video displays the loading icon for a few seconds (sometimes twice (icon appear, disappear, appear, disappear and that's all)), then disappear and nothing is being played. No errors on the screen, simply it doesn't work.

## Context (Environment)

### Installation

* [x] I installed the plugin via zip from the Releases page
* [ ] I´m using the Netflix Repo
* [ ] I´m using a different source (Please tell which)

Tried master and msl2 branches on various days: anyone works. Tried to remove preferences directory, cdm directory... Nothing works.

### Operating System

* [ ] Linux (x86/x64)
* [ ] OSX (x86/x64)
* [ ] Windows (x86/x64)
* [x] Linux (ARM)
* [ ] Android

#### Additional informatin on the environment
LibreELEC (Milhouse): devel-20181123210219-#1123-gcf48bb0 [Build #1123]

## Debug log
[http://ix.io/1uCY](http://ix.io/1uCY)

Start by reproducing playback on LibreELEC (Linux ARM) with the current release, then inspect the linked debug log at http://ix.io/1uCY. Compare the master and msl2 branches and verify whether removing the preferences and cdm directories changes the result. Done means the video starts playing without the loading icon stopping indefinitely.
