/**
|

|
|
* 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 1.4 factory must always create 1.4 IDrmPlugin interfaces, which are
|
||
|
|
* returned via the 1.0 createPlugin method.
|
||
|
|
*
|
||
|
|
* To use 1.4 features the caller must cast the returned interface to a
|
||
|
|
* 1.4 HAL, using V1_4::IDrmPlugin::castFrom().
