What did you do?
I wish to enable offline playback of my DRM videos. I am able to download the video if it is not DRM Encrypted, or if it is encrypted with Widevine. When i try to do the same with Playready encrypted videos, i get the following error : https://shaka-player-demo.appspot.com/docs/api/shaka.util.Error.html#value:6006

Shaka Error DRM.FAILED_TO_GENERATE_LICENSE_REQUEST (Failed to execute 'generateRequest' on 'MediaKeySession': Failed to create MF PR CdmSession (2154823689),NotSupportedError: Failed to execute 'generateRequest' on 'MediaKeySession': Failed to create MF PR CdmSession (2154823689),)

• Load the mpd url into the player, along with the license server url. The video plays in Microsoft Edge. When i try to download it, it throws the above error. When i loaded a widevine packaged url along with the license server url, i was able to download it and play it offline.

What did you expect to happen?
I expected the playready content to get downloaded and play offline.

What actually happened?

Are you planning send a PR to fix it?
