Problems solved by technology

[0004] However, in some cases, when encoding the image frame to be encoded according to other multiple reference image frames, it is necessary to wait for these reference image frames to be input to the encoding device, which will cause a large encoding delay

Embodiment Construction

[0028] Prior to the introduction of the technical solutions of this application, some background technical knowledge involved in the present application will be described. Hereinafter, as an alternative as an alternative to the technical solution of the present application, any combination can be made, which belongs to the scope of the present application embodiment. The present application includes at least some of the following contents in the following.

[0029] First introduce the nouns that may appear in this application.

[0030] Frame refers to a still picture in the video.

[0031] FPS (frames per second, frame rate) refers to the number of frames of the picture per second, or the number of graphics processors refreshed per second. The higher the frame rate, the more pictures refreshed in one second, the more true the video picture, the more smooth the movement in the video.

[0032] DR (DATA RATE, Code Stream) refers to the data traffic used in unit time, the larger the c...

Abstract

The embodiment of the invention discloses a video coding method and device, equipment and a storage medium, and belongs to the technical field of digital signal processing. The method comprises the following steps: acquiring a target image frame to be coded; under the condition that the number of the reference image frames of the target image frame does not meet the analysis condition, determining a frame type and a coding parameter of the target image frame according to a first mode, wherein the first mode is a mode in which the frame type and the coding parameter are determined not according to the reference image frame; and coding the target image frame according to the frame type and the coding parameter of the target image frame. According to the method, the waiting process that the coding device obtains the enough number of reference image frames under the condition that the number of the reference image frames of the image frame to be coded does not meet analysis is eliminated, the waiting time of the coding device is shortened, excessive parameters and complex calculation modes do not need to be introduced, and the coding time delay can be effectively reduced.

Description

Technical field [0001] The present application relates to the field of digital signal processing, and more particularly to a video encoding method, device, device, and storage medium. Background technique [0002] Before the video data transmission, the encoding device needs to encode the video image frame, and increase the data amount of the video image frame, and improve the transmission speed. [0003] In the relevant technique, before encoding a target image frame to be encoded, it is necessary to predict the frame type and coding parameters of the target image frame according to the other plurality of reference image frames, by calculating the target image frame using different encoding methods. The encoding loss will be brought to determine the most suitable frame type and encoding parameters of the target image frame. The encoding device encodes the target image frame according to the determined frame type and the encoding parameter, and obtains the code stream correspondi...
