A method implemented in an electronic device serving as a worker processing video and audio streams of a streaming platform system is disclosed. The method includes the electronic device requesting a task group from an orchestrator of the streaming platform system, where the orchestrator manages video and audio stream processing of the streaming platform system. The method also includes the electronic device receiving the task group allocated for the worker from the orchestrator, where the task group is allocated based at least partially on characteristics of the worker. The method also includes the electronic device initiating one or more task running processes to execute the allocated task group, and where each task running process performs at least one of processing one or more inputs corresponding to an incoming edge to the node, and producing one or more outputs corresponding to one or more outgoing edges from the node.
