Public bug reported:

https://bitmovin.com/demos/drm
I did a DRM check, but it is said to be "No, DRM".

chrome: // media-internals /
Although I confirmed it with,
It does not decrypt as "encryption scheme: Unencrypted" as shown below
What does not do DRM check
Is it a specification? (An audio codec error appears in other chromium builds 
and can not be played back.)
