摘要： 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.

摘要： A method implemented in an electronic device serving as a stream distributor distributing unicast video and audio streams of a streaming platform system is disclosed. The stream distributor receives a unicast data flow containing data of a video and audio stream from a load balancer, the unicast data flow being transmitted in user datagram protocol (UDP) packets. The method includes the electronic device detecting initiation of a maintenance activity on a virtual machine or its host associated with the stream distributor. The method includes the electronic device indicating a failure mode of the stream distributor, where the failure mode indication is to cause the load balancer to switch the unicast data flow to an alternate stream distributor. The method also includes the electronic device detecting a completion of the load balancer switching the unicast data flow to the alternate stream distributor, and halting the distribution of the unicast data flow.

摘要： A method executed by an electronic device to optimize resource utilization while processing media workflows by a video streaming platform is disclosed. In one embodiment, a request to initiate a set of training sessions is received, and for each training session, a set of training workflows to be processed is initiated and a task graph for each training workflow is created. Then a worker of the video streaming platform is assigned to each training session. The raw performance data from each assigned worker is then collected, and a platform performance profile is generated based on the raw performance data from the each assigned worker. The platform performance profile is used to predict resource requirements of media workflows to be processed by the video streaming platform. A system to perform the method and a storage medium storing instructions to perform the method are disclosed too.
