The Navigator.requestMediaKeySystemAccess() method returns a Promise for a MediaKeySystemAccess object.
Syntax
Navigator.requestMediaKeySystemAccess(keySystem, supportedConfigurations).then(function(mediaKeySystemAccess) { ... });
Parameters
- keySystem
- A
DOMStringidentifier of the key system. For examplecom.example.somesystemororg.w3.clearkey. - supportedConfigurations
- A non-empty
ArrayofMediaKeySystemConfigurationobjects. The first element with a satisfiable configuration will be used.
Note: Firefox implements an older version of the specification and does not require the second, supportedConfigurations, parameter to be defined. This is likely to change in the future (bug 1180482).
Return value
A Promise that resolves to a MediaKeySystemAccess object. If the given keySystem is not supported or none of the the requested configurations are satisfiable, the returned Promise is rejected with a DOMException whose name is NotSupportedError.
