DRM HAL

This is the underlying HAL implementation for MediaDrm/MediaCrypto (and their NDK counterparts).

Plugin-vendor-specific VTS modules

The interface DrmHalVTSVendorModule_V1 is compatible with all versions of the DRM HAL (hidl 1.0-1.4, aidl).

Please see ./1.0/vts/doc/Drm_Vendor_Modules_v1.pdf.
