We are trying to implement a server side API for encrypting live, DVR and VOD stream. We are able to encrypt live streams with key rotation features using IModuleOnHTTPCupertinoEncryption and METHOD_CHUNK_PLAYREADY. My question is, to encrypt the nDVR streams should we also use the IModuleOnHTTPCupertinoEncryption interface? As we have understood nDVR recorded streams are treated the same way as VOD but everytime a DVR is played the method onHTTPCupertinoEncryptionKeyVODChunk is not being called. Is there any other interface we can implement to set the Cupertino Encoding Info for DVRs in DVR store?
