* The sample Id is used as the IV in CTR mode. Block offset, starting at 0 and incremented by 1 after every 16 bytes, from the beginning of the sample is used as the Counter.

*

* The sample ID for each sample (media object) is stored as an ASF payload extension system with the ID of ASF_Payload_Extension_Encryption_SampleID = {6698B84E-0AFA-4330-AEB2-1C0A98D7A44D}. The payload extension can be stored as a fixed size extension of 8 bytes.

*

* The sample ID is always stored in big-endian byte order.
