Abstract: A video surveillance system and computer assisted method stores video streams of numerous video cameras installed throughout a facility (e.g., a school, an airport, etc.) and batch searches those video streams for relevant video frames that may show an individual with certain predetermined facial features. In some examples, the search range is limited by a specified time window, by certain designated cameras, and/or by certain predetermined areas of the facility. From those video streams, a collection of video clips containing the relevant video frames are identified and batch exported for later analysis by video surveillance personnel. In some examples, the collected video clips are compiled into a single composite video with the video clips being arranged by time for convenient and efficient viewing. In addition or alternatively, in some examples, the video clips are stored as separate files in a directory for viewing the video clips individually.

Abstract: Embodiments of the present disclosure efficiently create a single video stream from a plurality of individual video streams. The single video stream may embody a grid-based presentation of the individual video streams, without requiring separate objects for each stream. Such embodiments utilize particular hardware-accelerated multiplexing image pipelines executed via one or more graphics processing unit for efficient processing. Embodiments include a multiplexer component configured to perform the hardware-accelerated image pipelines executed on one or more GPUs. Some such embodiments output a common output video that may be outputted for a variety of use cases, including but without limitation outputting to a display wall, outputting to one or more web-based client devices, outputting locally to a client device, and outputting locally to a multimonitor display.

Abstract: A method for delivering a web page that displays a video includes delivering a requested web page with a WebAssembly Module to a web browser of a requesting device. The WebAssembly Module includes a plurality of video decoders each for decoding a corresponding one of a plurality of video encoding formats. An encoded video is delivered for display by the requested web page, the encoded video being encoded in a particular one of the plurality of video encoding formats. The encoded video is decoded using a respective one of the plurality of video decoders of the WebAssembly Module that corresponds to the particular one of the plurality of video encoding formats of the delivered encoded video.
