摘要:
A method including: extracting a set of video features representing properties of a video segment; generating a set of bitrate-resolution pairs based on the set of video features, each bitrate-resolution pair in the set of bitrate-resolution pairs defining a bitrate and defining a resolution estimated to maximize a quality score characterizing the video segment encoded at the bitrate; accessing a distribution of audience bandwidths; selecting a top bitrate-resolution pair in the set of bitrate-resolution pairs; selecting a bottom bitrate-resolution pair in the set of bitrate-resolution pairs; selecting a subset of bitrate-resolution pairs in the set of bitrate-resolution pairs based on the distribution of audience bandwidths, the subset of bitrate-resolution pairs defining bitrates less than the top bitrate and greater than the bottom bitrate; and generating an encoding ladder for the video segment comprising the top bitrate-resolution pair, the bottom bitrate-resolution pair, and the subset of bitrate-resolution pairs.
