API Changes

See https://github.com/video-dev/hls.js/blob/v1.3.0-beta.1/docs/API.md for API details and examples.

Config changes

• Added drmSystems for defining key-system specific license urls and certificates
  • drmSystems['com.widevine.alpha'].licenseUrl replaces widevineLicenseUrl (deprecated but still supported)
• drmSystemOptions takes additional optional arguments used for defining MediaKeySystemConfiguration
• licenseXhrSetup
  • includes additional keyContext and licenseChallenge arguments
  • is optionally async: takes a return value of a Uint8Array, a Promise which resolves with a Uint8Array or undefined (returning a value transforms the licenseChallenge license request body)
• licenseResponseCallback includes an additional keyContext argument
• Changes to the integration of EMEController and KeyLoader may impact custom config.emeController implementations
  • A new keyLoader constructor argument has been added to StreamController, AudioStreamController, and SubtitleStreamController via BaseStreamController (this allows all stream controllers to share a common KeyLoader instance)
  • KeyLoader utilizes an instance of EMEController for handling HLS Keys

New Error Event ErrorDetails constants have been added to help with identifying issues when negotiating with CDMs

• New KEY_SYSTEM_ERROR type error details:
  • KEY_SYSTEM_SERVER_CERTIFICATE_REQUEST_FAILED
  • KEY_SYSTEM_SERVER_CERTIFICATE_UPDATE_FAILED
  • KEY_SYSTEM_NO_INIT_DATA
  • KEY_SYSTEM_SESSION_UPDATE_FAILED
  • KEY_SYSTEM_STATUS_OUTPUT_RESTRICTED
  • KEY_SYSTEM_STATUS_INTERNAL_ERROR

Event object additions

• MANIFEST_LOADED event data includes sessionKeys
• MANIFEST_PARSED event data includes sessionData and sessionKeys
• KEY_LOADED event data includes keyInfo

Fragment object changes

• The levelkey property has been replaced by an array: levelkeys
  • (levelkey has been deprecated and will not be supported)

LevelDetails object additions

• encryptedFragments property has been added (assists in dealing with "clear-lead" streams where initial segments are not encrypted)
