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.
