Description
Have you read the FAQ and checked for duplicate issues: yes
What version of Shaka Player are you using: 2.1.3
Can you reproduce the issue with our latest release version: yes
Can you reproduce the issue with the latest code from master: unknown
Are you using the demo app or your own custom app: custom app - cannot access Chromecast remote debugging in demo app
If custom app, can you reproduce the issue using our demo app: N/A
What browser and OS are you using: Chromecast 2
What are the manifest and license server URIs:
Cannot provide at this point (our signed licenses expire after 5 minutes) but it wouldn't surprise me if it was reproducible with the PlayReady test assets in the demo (which error when casting as well).
We use DRMtoday with both PlayReady and Widevine schemes in our manifests.
What did you do?
Play a DASH video that supports both PlayReady and Widevine on a Chromecast 2
What did you expect to happen?
The license request (either PlayReady or Widevine) should succeed and the video should play.
What actually happened?
The license request failed with a 415 unsupported media type, as it is sent with Content-Type: text/html.
Manually adding request.headers['Content-Type'] = 'text/xml; charset=utf-8'; to the license request filter resolves the issue (as does removing PlayReady license servers from the configuration to make Shaka use Widevine instead, which works fine).
The exact same code works fine in Edge/IE11 with PlayReady (in 2.1.1 / 2.1.3).
I suspect the issue is caused by the correct header not being added in https://github.com/google/shaka-player/blob/9d9d1c70/lib/media/drm_engine.js#L1122
