Abstract
A method for processing video data is performed by a data processing unit (DPU). The method includes identifying, by the DPU of an edge device, a contextual stitching trigger event; in response to identifying the contextual stitching trigger event: identifying video data chunks, contextual metadata, indexing metadata, and authentication and authorization (AA) metadata associated with the contextual stitching trigger event; generating a virtual blob based on the video data chunks, contextual metadata, indexing metadata, and authentication and authorization AA metadata; making a first determination that a playback request is obtained from a user, wherein the playback request comprises user authentication information; and in response to the first determination: making a second determination that the user authentication information matches the AA metadata; and in response to the second determination; encoding the video data chunks into a single stream and initiating playback for the user.
