Abstract

The embodiment of the application provides a transcoding task allocation method, equipment and a readable storage medium, wherein after receiving a transcoding task from a terminal, electronic equipment selects an absolute idle card randomly preferentially and allocates the transcoding task when the absolute idle card of an encoding module is idle is sufficient, and selects a relative idle card and allocates the transcoding task when the absolute idle card of the encoding module is idle is insufficient, so that the aim of improving load balance is fulfilled while randomly selecting a hardware transcoding card is fulfilled. In addition, in the field of AI analysis, after the edge AI gateway receives the AI request from the terminal equipment, randomness and load balancing are considered when the service node is selected, so that the phenomenon that a plurality of AI requests are accumulated to the same service node, which results in poor real-time performance and service node performance bottleneck, is avoided.
