Multimedia link debugging method, system and equipment of simulation platform and medium

The invention discloses a multimedia link debugging method, system and device for a simulation platform and a medium, and the method comprises the steps: carrying out the data processing of each subsystem in a multimedia link, and transmitting image data obtained through data processing to a preset memory space; exporting the image data of each subsystem in the preset memory space to an external memory; taking each subsystem as a target subsystem in sequence, and obtaining image data of the target subsystem from an external memory; comparing the image data of the target subsystem with expected image data corresponding to the target subsystem to obtain a comparison result; and according to a comparison result, judging whether the target subsystem has a fault or not. According to the embodiment of the invention, the image data output by each subsystem are respectively obtained through the preset memory space, and whether each subsystem fails or not is judged based on the image data output by each subsystem, so
