Abstract
In one embodiment, a method includes encoding a media file using a variable bitrate encoding algorithm based on a plurality of bitrate ranges to generate a set of encoded segments. For each bitrate range, an encoded segment for each segment of the media file is determined from the set of encoded segments based on a quality level of the encoded segment and each bitrate range. The method then identifies a playlist for each bitrate range including the encoded segment for each segment of the media file that was determined for each bitrate range. At least one playlist includes an encoded segment that was generated based on another bitrate range using the variable bitrate encoding algorithm.
