Data transmission control method and device, electronic equipment and medium

The embodiment of the invention discloses a data transmission control method and device, electronic equipment and a medium. The method comprises the following steps: monitoring current hardware performance data of front-end equipment; adjusting data transmission parameters according to a comparison result of the current hardware performance data and a theoretical hardware performance data upper limit value; wherein the data transmission parameter comprises at least one of the current processing service, the resolution of the data output mode corresponding to the transmission data and the frame rate; and controlling the front-end equipment to transmit data to the target equipment according to the adjusted data transmission parameters. According to the technical scheme, when the equipment transmits the audio and video data, the current processing service and the relevant parameters in the data transmission mode are adjusted according to the current hardware performance data of the equipment, so that the audio a
