Apparatuses, computer program products, and computer-implemented methods for hardware-accelerated video stream synthesizing

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. Some embodiments generate utilize an image primitive frame that is sharable between multiplexers for use in different use cases without need to repeat processing steps.
