Abstract: 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.
