Abstract: Methods and apparatus are described for estimating the peak bit rate for content and specifying the BANDWIDTH tag value for HLS content. This disclosure also describes techniques by which live content and VOD content can be stitched together in a way that harmonizes the different requirements for the BANDWIDTH tag for the different types of content.

Abstract: Various embodiments of methods, apparatus, systems, and non-transitory computer-readable storage media for buffer recovery in segmented media delivery applications are described. Segments of a live media presentation are stored in a buffer. A number of segments in the buffer is determined to have fallen below a threshold. Based on that determination, various buffer recovery techniques may be performed. In one such technique, a buffered segment is decoded into a first set of video frames, the first set of video frames having a first playback duration. The first set of video frames is encoded into a second set of video frames having a second playback duration that is longer than the first playback duration.
