CAUSE
Generally speaking, users can get asset information by using Backlot API like /v2/assets/(embedcode) . Note that the “Widevine Asset ID” is not included in this result.
Note: “Widevine Asset ID” is a unique ID which is required by Widevine DRM process. A transcoding system should generate / assign it to each asset. The “Widevine Asset ID” may be required when Widevine stream would be used as a remote asset.
HOW TO RESOLVE
Users can get “Widevine Asset ID” from “/v2/assets/(embedcode)/drm_attributes/widevine” Backlot API. This ID is determined by Ooyala Transcode System (OTS) during the initial transcoding. This ID will not be changed, even if the asset was reprocessed.
API Sample:
GET /v2/assets/(embed_code)/drm_attributes/widevine
->
{
"id": "25447739",
"drm_type": "widevine"
}
