Systems and methods described herein provide for novel boundary generation features for interleaving additional content into media content. Media content may be received which includes a video and audio portion. An unencrypted encode of the video portion may be generated. A first set of time stamps for the video portion may be generated using a computer vision algorithm. A second set of time stamps for the video portion may be generated for identifying IDR frames using a first algorithm. A third set of time stamps may be generated to serve as boundaries for interleaving additional content into the media content based on a priority algorithm that uses the first set of time stamps and the second set of time stamps. The video portion may be encoded using the third set of time stamps to determine the IDR frames for the media content.

Generating boundary points for media content

A system for utilizing media content reference point information to perform media content encoding, and supplemental content stitching and/or insertion. Media content can be encoded and packaged based on boundaries of the media content. The boundaries can be received from a third-party and/or generated via an automated process. Target boundaries can be selected based on accuracy levels associated with the received and/or generated boundaries. Supplemental content can be stitched and/or inserted into packaged media content based on audio and video content of the packaged media content being aligned.

Media content boundary-aware encoding

Media content boundary-aware supplemental content management

Methods and apparatus are described that relate to stitching different streams of high dynamic range (HDR) content together and handling HDR metadata mismatches between the differently produced content streams.

High dynamic range video content stitching

Methods and apparatus are described for facilitating the client-side caching of media content based on one or more properties of the media content. Information relating to the cacheability of different types of content is communicated to the media player on a client device in the manifest or playlist employed by the media player to request fragments of the media content. The media player uses this information to make decisions about how to cache the corresponding content.

Client-side caching of media content

Techniques for video fragment aware audio packaging that ensure a periodic and best alignment of audio and video fragments at any corresponding audio and video fragments are described. As one example, a video fragment aware audio packaging service determines a number of audio frames for a corresponding video fragment of video frames and generates an audio fragment that includes those audio frames, with flexible choices of video fragment duration, which may be considered and decided for device compatibility or content encoding optimization purposes.
