Abstract: A content streaming system and methodology for facilitating the management of content streaming. A video packaging and origination service receives streaming content that is organized according to content segments. Individual content segments will be encoded according to a plurality of encoding bitrates including a reference bitrate and one or more additional renditions. The one or more additional renditions include pointers to the baseline rendition.

Abstract: Techniques for managing encoder configuration based on content delivery network performance are described. A computer-implemented method may include obtaining availability metrics from one or more content delivery networks (CDNs), the availability metrics associated with one or more content streams provided by the one or more CDNs, determining at least one CDN has less than a threshold capacity based at least on the availability metrics, and sending a request to one or more encoders associated with the one or more content streams to reduce a quality of at least one of the one or more content streams based at least on the availability metrics.

Abstract: Quality parameters, such as encoding bitrate, can be determined for the providing of media content based at least in part upon aggregate consumption data. An unknown number of media players can obtain content at a bitrate that depends upon network conditions, and encoders can use variable bitrate encoding, such that egress bandwidth usage can vary widely over time. Aggregate consumption data can be obtained for the various client devices to project the egress costs for a particular period. If the projected resources deviate unacceptably from the target for the period, new quality setting values can be determined, such as new maximum, minimum, target bitrate, or target quality values for the various quality levels. These settings can be automatically applied or suggested to customers, who can then accept any or all of the suggestions, or choose to adjust at least some of the settings based on the suggestions or cost projections.
