This invention discloses a high-concurrency real-time IP transcoding system for x86 architecture edge computing nodes, relating to the field of edge computing transcoding technology. The system includes an edge computing node receiving real-time Internet Protocol (IP) video streams from multiple video sources, performing protocol decapsulation and bitstream extraction to separate the basic video bitstream, basic audio bitstream, and metadata.
