Parameters

drmInfo

DrmInfo built by the HLS manifest parser

Returns

the helper

Implemented in AampWidevineDrmHelperFactory, AampPlayReadyHelperFactory, AampVgdrmHelperFactory, AampClearKeyHelperFactory, and AampVerimatrixHelperFactory.

appendSystemId()

virtual void AampDrmHelperFactory::appendSystemId ( std::vector< std::string > &  systemIds ) const
