I am testing DRM and found viblast goo d but unfortunately when I try to configure it it does not play my video.
I am attatching my code used for it
The stream plays well with your page and we see the request to widevine server.
Do you load the test page via HTTPS protocol?
With the recent versions of the Chrome browser there are restrictions related to the playback of protected content - the page must be loaded via HTTPS or if you want to test to access it locally (to serve from localhost).
I found out that the player doesn't even make connection to licensing server
