DASH + Widevine

[pedrosilvabos]

Hello @l1bbcsg @reeFridge @nomean42
could you please help with the following issue ?

VERSION: 2.7.5
DEVELOPING IN WINDOWS ENVIRONMENT
PROBLEM: Unable to play a DASH content with Widevine DRM under Tizen and Webos.

ATTEMPTED SOLUTIONS (FOR WEBOS):
Followed the drm.md documentation with the playready example (that I tried and works, plays tears of steel) and followed the instructions:

• Created widevine_client.js in node_modules\zombiebox\zb\device\drm\widevine_client.js, to save the mpd URL and the License Aquision Server Url
• Altered drm.js in node_modules\zombiebox\zb\device\drm\drm.js , added the widevine DRM
• Created widevine_hook.js in node_modules\zombiebox-platform-webos\lib\widevine-hook.js , created the widevine hook with the configurations from the WebOS website
• Altered stateful-html5-video.js in node_modules\zombiebox-platform-webos\lib\stateful-html5-video.js, changed to accept widevine and attach the widevine_client to the widevine_hook ALSO added WIDEVINE to isDRMSupported
• Altered player.js in src\scenes\player\player.js before the invocation of the play method, I attach the DRM with the WidevineClient passing in the argument an object with the stream URL and the License Aquision Server URL

All the files I created and Altered are in a zip file attached to this ticket, for your review.

NOTES:
I have not tried for TIZEN, since I would have the exact same approach, and I believe that once I could have it working on WebOs it would be easy to replicate the steps for TIZEN (I think)
The values for widevine_hook(_drmSystemId, _drmMessageType, WidevineCredentialsInfo xml initializer) were obtained by looking at the webos widevine documentation here:
https://webostv.developer.lge.com/develop/app-developer-guide/playing-drm-content/

RESULT:
The player loads but the video never plays
