This is a software only implementation of the OEMCrypto library for testing the rest of the DRM code. It currently implements the OEMCrypto_DecrtyptCTR function using a clear key. I've included the license request code so the rest of the group can play with it, but I have only tested part of it. This patch also has some makefiles and an integration testing. You should be able to generate the shared library libclearkeydrmengine.so with cd vendor/widevine/libclearkeydrmengine; mm You can create some unit test and integration test programs from the directories: vendor/widevine/libwvdrmengine/oemcrypto/test vendor/widevine/libclearkeydrmengine/test vendor/widevine/libclearkeydrmengine/inttest vendor/widevine/libclearkeydrmengine/crypto/test This change also addresses some comments about comments in OEMCryptoDASH.h which were made in https://googleplex-android-review.googlesource.com/257323 Change-Id: Id6899b9f8d2f09e09be2ea493baa83a6b929073b
