requestMediaKeySystemAccess method
- String keySystem,
- JSArray<
MediaKeySystemConfiguration> supportedConfigurations
The Navigator.requestMediaKeySystemAccess()
method
returns a Promise
which delivers a MediaKeySystemAccess
object that can be used to access a particular media key system, which can
in turn be
used to create keys for decrypting a media stream. This method is part of
the
Encrypted Media Extensions API,
which brings support for encrypted media and DRM-protected video to the
web.
This method may have user-visible effects such as asking for permission to
access one
or more system resources. Consider that when deciding when to call
requestMediaKeySystemAccess()
; you don't want those requests
to happen at inconvenient times. As a general rule, this function should
be called only
when it's about time to create and use a MediaKeys object by calling the
returned MediaKeySystemAccess
object's
MediaKeySystemAccess.createMediaKeys method.
