/**

* IDrmFactory is the main entry point for interacting with a vendor's
|
|
* drm HAL to create drm plugin instances. A drm plugin instance
|
|
* creates drm sessions which are used to obtain keys for a crypto
|
|
* session so it can decrypt protected video content.
|
|
*
|
|
* The 1.2 factory must always create 1.2 IDrmPlugin interfaces, which are
|
|
* returned via the 1.0 createPlugin method.
|
|
*
|
|
* To use 1.2 features the caller must cast the returned interface to a
|
|
* 1.2 HAL, using V1_2::IDrmPlugin::castFrom().
|
|
*
|
|
* The IDrmFactory hal is required because all top-level interfaces
|
|
* have to be updated in a minor uprev.
