according to the SAMPLE-AES encryption method cited by the HLS spec (informational RFC called draft-pantos-http-live- streaming). This encryption method is being incorporated in the Common Encryption specification ISO/IEC 23001-7 3rd Edition as the 'cbcs' scheme. Parsing of the stream requires it to be prefixed with extra TS packets that carry encryption metadata. These packets are formatted according to ISO/IEC 23001-9 "Common encryption of MPEG-2 transport streams". This CL is dependent on a prior CL (1490613005) that allows conveyance of the extended encryption metadata through the pipeline.
