摘要： Systems and methods for processing a live video stream are provided. An ingestion component receives segments of a live video stream in association with a request to process the live video stream. A control component generates an instruction graph for the live video stream based on predetermined criteria. The instruction graph defines a workflow for processing the live video stream, the workflow comprising a set of services for processing the segments. A transcoding component employs a subset of the services to process the segments based at least in part on the instruction graph and a distribution component then streams the segments to a device in response finishing process of the segments. With the live video processing system, segments of a video stream are processed and distributed as they are received. Thus segments of the video stream are processed and distributed prior to processing of the entire video stream.

摘要： A system and method for a live streaming platform that can redundantly process input streams in parallel ingestion pipelines is disclosed herein. Ingested input streams in the parallel pipelines can be segmented using a segmentation function that creates identical segments in each of the streams in the pipelines. If errors occur, or there are disruptions in one or more of the input streams or pipelines, the live streaming platform can ensure that segments are identifiable and different parts of the pipelines can join a main stream at different points in time without disruption.

摘要： A method for enabling visual browsing of a plurality videos includes identifying a low frame rate version for each video from a plurality of videos using one or more computers, wherein the low frame rate version of each video from the plurality of videos is at a frame rate that provides a visually perceptible pause between successive visually distinct frames; and outputting information that defines a visual display, wherein the visual display presents a plurality of graphical representations each corresponding to a respective video from the plurality of videos, wherein each graphical representation from the plurality of graphical representations includes the low frame rate version of the respective video from the plurality of videos.
