Abstract

The invention provides a video code rate adjustment method and device, equipment and a storage medium. The method comprises the steps of obtaining a current video code rate of video data transmitted by video transmission equipment, current position information of the video transmission equipment and current driving information of a vehicle where the video transmission equipment is located; determining current distance information between a corresponding base station in an area where the video transmission equipment is located and the video transmission equipment according to the current position information; inputting the current video code rate, the current position information, the current distance information and the current driving information into a deep neural network model which is trained to be convergent, and outputting a predicted video code rate through the deep neural network model; and determining a new video code rate according to the predicted video code rate, and adjusting the current video code rate of the video data transmitted by the video transmission equipment to the new video code rate. According to the method provided by the invention, the jamming phenomenon can be effectively avoided, the video transmission quality is not influenced, and the real-time performance and the stability of streaming media transmission are better ensured.

Description

technical field [0001] The present application relates to the technical field of data transmission, and in particular to a method, device, device and storage medium for adjusting a video code rate. Background technique [0002] With the rapid development of mobile terminal technology, mobile terminals such as vehicle-mounted devices have more and more functions. Real-time video transmission has become one of the basic functions that vehicle-mounted devices must meet. [0003] Car video transmission mainly relies on 4G network. During the driving process, the vehicle will pass through multiple base stations and switch between multiple base stations, which will cause network instability, delay jitter, packet loss and other phenomena, and cannot guarantee video quality. The possibility of data transmission reduces the quality of the transmitted on-board video. In the existing streaming media transmission system, there are mainly two coding transmission methods, static code rat...
