This CL updates has several changes.
The document WidevineModularDRMSecurityIntegrationGuideforCENC_v14.pdf
had an incorrect definition of the PST_Report structure. The header
file had the correct definition. This has been updated and the version
number of the document was rolled to 14.1
The unit tests TwoHundredEntries has been modifed to make sure that if
the usage table is full, then OEMCrypto will return the error
OEMCrypto_ERROR_INSUFFICIENT_RESOURCES. This is important for the CDM
layer to correctly delete old licenses and secure stops when this
happens.
Several other unit tests covering corner cases have been added.
The reference code has been cleaned up a bit. Some logging that might
be dangerous has been removed.
This renames the "mock" code to "reference" because that's really what
it is. Also, some code has been moved from the CDM repo to a common
utility directory so that it can be included here, and the oemcrypto
unit tests can now be built without having access to a current CDM
repo.
There are no functionality changes in this CL.
This change updates the copyright notice to make it more clear that
the code is distribued under the Widevine Master License Agreement.
It also updates the unit tests and sample code to correct the useage
of AES 256. AES 256 is used to decrypt entitled content keys, but it
is not used to decrypt key control blocks.
