Derived from WidevinePsshData. The JSON format of this proto is used in Widevine HLS DRM signaling v1. We cannot build JSON from WidevinePsshData as |key_id| is required to be in hex format, while |bytes| type is translated to base64 by JSON formatter, so we have to use |string| type and do hex conversion in the code.

• repeated string key_ids = 2

• optional string provider = 3

  Content provider name.

• optional bytes content_id = 4

  A content identifier, specified by content provider.
