Abstract
In one embodiment, a method encodes a first set of segments of a media file based on a first bitrate range to generate a first set of encoded segments. It is then determined when an encoded segment for the first bitrate range includes a bitrate that satisfies a second bitrate range. When the encoded segment for the first bitrate range includes the bitrate that satisfies the second bitrate range, the method does not encode a segment in the first set of segments that corresponds to the encoded segment when the media file is encoded based on the second bitrate range to generate a second set of encoded segments for the second bitrate range. A first playlist for the first bitrate range is identified and a second playlist for the second bitrate range is identified. The second playlist also includes the encoded segment that was encoded for the first bitrate range.
