Abstract: Adaptive video transcoding based on parallel chunked log analysis is described. The adaptive video transcoding method comprises receiving an intermediate video stream generated from an intermediate transcoding. The method also receives an intermediate transcoding log stream associated with the intermediate video stream. The method partitions the intermediate video stream into a plurality of video chunks, where each video chunk corresponding to a portion of video data of the video stream. The method further generates video chunk statistics for each of the video chunks using the intermediate transcoding log stream and transcoding parameters for each of the video chunks based on the generated video chunk statistics. The method transcodes each of the video chunks to a target format in parallel based on the generated transcoding parameters. The method assembles the transcoded video chunks into a target video stream in the target format.

Abstract: Methods and devices are described for generating a recipe for creating a clip. A clip request may be received at a server, such as a content server. The clip request may be related to a clip including audio and/or video. The server may include one or more processors and a cache, the cache including chunks. Each chunk may store a predetermined positive number of bytes of data. The server may search the cache to determine whether the clip is to be generated from a recipe stored within the cache. The recipe may include one or more tasks. The server may generate the clip in view of the one or more tasks of the recipe. The server may transmit a clip response comprising the clip to the client device.

Abstract: Methods and devices are described for generating a recipe for creating a clip. A recipe request can be received at a server, such as a recipe server. The recipe request may be related to a clip including audio and/or video. The server can generate a recipe for creating the clip using one or more slices of a data source. The recipe can include one or more tasks that can include a data-source task which can include a specification of the data source and slice definitions for the one or more slices. The data source can include a video and/or audio data source. A slice definition can include a slice value and a slice offset for locating a respective slice within the data source. The recipe can then be transmitted from the server.
