Abstract: A method implemented in an electronic device serving as an orchestrator managing video and audio stream processing of a streaming platform system is disclosed. The method includes the electronic device receiving a request to process a video source and creating a task graph based on the request, where the task graph is a directed acyclic graph of tasks for processing the video source, where each node of the task graph represents a processing task, and where each edge of the task graph represents a data flow across two processing tasks and corresponding input and output of each processing task. The method also includes the electronic device estimating resource requirements of each processing tasks, and splitting the task graph into a plurality of subsets, wherein each subset corresponds to a task group to be executed by one or more workers of a plurality of processing units of the streaming platform system.
