Dynamic generation of video manifest files

摘要

Some content players use manifest files to obtain and play video content. The manifest files include metadata information for obtaining video chunks that together constitute a full video, and can be used by content players to obtain the chunks, stitch them together, and render the video as a stream. Described herein are techniques for dynamically generating manifest files. A request for a manifest file is received, such as from a video player. Manifest file contents are retrieved, such as from an original manifest file. A manifest file to be used by a video player to fetch video chunks is then dynamically generated and returned.

a set of one or more processors configured to, using a set of one or more interfaces:
receive, from a video player, a request for a manifest file, wherein the request includes location information associated with the manifest file;fetch, from a remote source, the manifest file using the location information included in the request;rewrite the fetched manifest file, wherein the rewriting of the fetched manifest file is based at least in part on global information aggregated from a plurality of video players; andreturn the rewritten manifest file to the video player, wherein the video player is configured to obtain video data according to the rewritten manifest file; and a memory coupled to the set of one or more processors and configured to provide the set of one or more processors with instructions.
