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.

Method for generating video- and audience-specific encoding ladders

A method including: populating an encoding ladder with a subset of bitrate-resolution pairs, from a set of bitrate-resolution pairs, based on a distribution of audience bandwidths; receiving a first request for a first playback segment, at a first bitrate-resolution pair in a encoding ladder, in the video from a first device; in response to determining an absence of video segments, at the first bitrate-resolution pair and corresponding to the segment, in a first rendition cache: identifying a first set of mezzanine segments, in the video, corresponding to the first playback segment; assigning the first set of mezzanine segments to a set of workers for transcoding into a first set of video segments according to the first bitrate-resolution pair; storing the first set of video segments in the first rendition cache; and based on the first request, releasing the first set of video segments to the first device.

Methods for generating video-and audience-specific encoding ladders with audio and video just-in-time transcoding

A method includes, during an initial time: receiving a manifest request, for a video, from a device associated with a first address; generating an identifier associated with the first address; generating a manifest defining a set of segments available for the video; and serving the manifest. The method further includes, during a first time: receiving a first request for a first segment, in the set of segments, the first request associated with the first address and the identifier; and based on association between the first address and the identifier, serving the first segment to the first address. The method also includes, during a second time: receiving a second request for a second segment in the set of segments, the second request associated with a second address and the identifier; and based on disassociation of the second address and the identifier, withholding delivery of the second segment to the second address.

Methods for identifier-based video streaming and sessionization

A method includes, at a first time: receiving a request for video content from a first user; generating a fingerprint for the first user; associating the first user with a first user population—assigned to a first CDN and receiving the video content from the first CDN during the first time period—based on the fingerprint; and accessing a first metric for distribution of video content from the first CDN to users of the first user population. The method also includes, at a second time: selecting a second user within the first user population; identifying a second CDN distinct from the first CDN; reassigning the second user to the second CDN; and accessing a second metric for distribution of the video content from the second CDN to the second user; and, in response to the second metric exceeding the first metric, reassigning the first user to the second CDN.
