2001
An attempt was made to play back a Fairplay protected stream, but no DRM configuration was provided in the drm.
In order to play back Fairplay protected content, it is necessary to specify a AppleFairplayDRMConfig in drm, as the DRM licenses required to decode and play back the content can otherwise not be requested by the player.
An example Fairplay DRM configuration can be seen in AppleFairplayDRMConfig.
