Abstract: Provided is a method for detecting live streaming jitter, a device, and a medium. An implementation is: calculating, for a live stream transmitted by an edge content delivery network (CDN) node in a CDN, quality information of the live stream based on a transmission frame rate and a viewer count of the live stream; calculating quality information of the edge CDN node based on the quality information of the live stream; and determining, based on the quality information of the edge CDN node, whether jitter occurs at the edge CDN node.

Abstract: Provided is a multimedia data stream processing method, an electronic device and a storage medium, relating to the field of artificial intelligence, and specifically, to the technical fields of cloud computing, media cloud technology, and the like, which may be applied to scenes such as smart cloud. The multimedia data stream processing method includes: allocating a plurality of sub-streams of a multimedia data stream to a plurality of edge resource nodes, where the multimedia data stream is segmented into a plurality of slices and each of the plurality of sub-streams includes a part of the plurality of slices of the multimedia data stream; and scheduling the plurality of edge resource nodes to provide the plurality of sub-streams of the multimedia data stream for a terminal device.
