VIDEO STREAM FRAME RATE ADJUSTMENT METHOD AND APPARATUS, AND DEVICE, MEDIUM AND PRODUCT

The present application relates to a video stream frame rate adjustment method and apparatus, and a device, a medium and a product. The method comprises: acquiring the current image frame, which is required to generate a video stream; determining a subjective evaluation parameter of the current image frame, wherein the subjective evaluation parameter comprises a reference frame rate which is suitable for encoding the current image frame, and a subjective quality index which can be expected to be obtained by means of performing encoding according to the reference frame rate; inputting an outlet bandwidth of an encoder into a parameter optimization model, so as to obtain an approximation function, under the outlet bandwidth, for representing a mapping relationship between an encoding frame rate and an objective quality index; and applying the approximation function to find a numerical approximation point corresponding to the subjective evaluation parameter, and obtaining, as an optimal frame rate for encoding t
