Abstract
Embodiments of a system and method for local generation of streaming content with a hint track are described. Embodiments may include receiving a first version of encrypted content comprising encrypted content samples that each include media content and non-content information. Embodiments may also include receiving a hint track including packet header information for a stream of media packets from which the media content was sourced, and offset information identifying locations of encrypted media content within the encrypted content samples. Embodiments may include generating a second version of the encrypted content for streaming, which may include, based on the information of the hint track, identifying the location of media content within the encrypted content samples. Embodiments may include generating media packets within the second version of the encrypted content, each of those media packets including header information from the hint track and the identified media content from the encrypted content samples.
