Shaka Player Demo Fails to Play Streams from Shaka-Streamer

[PanikParty]

I deployed the shaka-streamer to a compute instance on GCP and configured both VOD and live pipelines to emit DASH to a public bucket. The clear content worked as expected, but playback of the WideVine protected content fails with "NO_LICENSE_SERVER_GIVEN".

The encryption settings for both pipelines are identical, and taken from the included examples, they read as follows: encryption:

  # Enables encryption.
  # If disabled, the following settings are ignored.
  enable: True
  # Content identifier that identifies which encryption key to use.
  # This will default to a random content ID, so this is optional.
  content_id: '1234'
  # Key server url.  An encryption key is generated from this server.
  key_server_url: https://license.uat.widevine.com/cenc/getcontentkey/widevine_test
  # The name of the signer.
  signer: widevine_test
  # AES signing key in hex string.
  signing_key: 1ae8ccd0e7985cc0b6203a55855a1034afc252980e970ca90e5202689f947ab9
  # AES signing iv in hex string.
  signing_iv: d58ce954203b7c9a9a9d467f59839249
  # Protection scheme (cenc or cbcs)
  # These are different methods of using a block cipher to encrypt media.
  protection_scheme: cenc
  # Seconds of unencrypted media at the beginning of the stream.
  clear_lead: 10

Does the player require an explicit declaration for the license server? If so, is it the same URL used as the keyserver URL in the pipeline config?

My apologies, looking at some of the previous posts, I understand that the player must be explicitly configured to use the UAT server. The following changes to the player application made all the difference.

const licenseServer = 'https://cwip-shaka-proxy.appspot.com/no_auth';

  player.configure({
    drm: {
      servers: {
        'com.widevine.alpha': licenseServer
      }
    }
  });
