21/**
22 * IDrmFactory is the main entry point for interacting with a vendor's
23 * drm HAL to create drm plugin instances. A drm plugin instance
24 * creates drm sessions which are used to obtain keys for a crypto
25 * session so it can decrypt protected video content.
26 *
27 * The 1.1 factory must always create 1.1 IDrmPlugin interfaces, which are
28 * returned via the 1.0 createPlugin method.
29 *
30 * To use 1.1 features the caller must cast the returned interface to a
31 * 1.1 HAL, using V1_1::IDrmPlugin::castFrom().
