Tizen persistent license support

According to the Tizen media specification (https://developer.samsung.com/tv/develop/specifications/media-specifications) Tizen 4.0 and newer implement a version of the EME spec (5th July 2016) that should support persistent DRM licenses. 

 

I've tried implementing this license persistence according to the EME spec (https://www.w3.org/TR/encrypted-media) but it fails to update the keySession on my tizen 4.0 TV with the error "Updating session failed. (99999)". The only information about that error is an open issue for shaka player and persistent license support on Tizen 3.0 (https://github.com/google/shaka-player/issues/894).

 

I could not find any concrete information on this topic online so my question is: Does Tizen(4.0 or newer) actually support drm license persistence via the EME?

 

kind regards,

Hannes
