Code rate determination method and device of multimedia resources, electronic equipment and storage medium

The invention provides a code rate determination method and device of multimedia resources, electronic equipment and a storage medium, and belongs to the technical field of multimedia. The method comprises the following steps: acquiring a first buffer capacity of a multimedia resource and a first sending rate of the multimedia resource; determining a buffer change gradient of a buffer area of the receiving end based on the first buffer capacity and the first sending rate; determining a target function based on the buffer change gradient and a first code rate; under the condition that the function value of the objective function is minimum, a second code rate is determined, and the second code rate is used for representing the code rate of the multimedia resources at the current moment. According to the technical scheme, the stability of the data volume of the multimedia resources cached in the buffer area of the receiving end can be maintained, the definition and fluency of the multimedia resources are improv
