Abstract

The invention discloses a video coding method and device, belonging to the technical field of computers. The method includes the following steps: acquiring a current coding unit, wherein the current coding unit is any coding unit included in a video frame image; selecting part of comparison frames from a comparison frame list; and acquiring a first rate distortion cost evaluation value of the current coding unit according to a motion vector set and the selected part of comparison frames. The device comprises a first acquisition module, a selection module and a second acquisition module. According to the scheme of the invention, the calculation amount for calculating the minimum rate distortion cost can be reduced, and the efficiency of obtaining the minimum rate distortion cost can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a video coding method. Background technique [0002] In the process of transmitting video data, in order to save bandwidth, the video data needs to be compressed and coded to reduce the size of the data packet of the transmitted video data. [0003] In the traditional technical solution for encoding video images, the comparison frame set includes a large number of comparison frames and a large number of motion reference combinations, which will lead to an increase in the number of times to calculate the rate-distortion cost, which will lead to a larger calculation amount and reduce the encoding cost. efficiency. Contents of the invention [0004] In order to solve the above problems, an embodiment of the present invention provides a video coding method. Described technical scheme is as follows: [0005] A video coding method, comprising: acquiring a motion vector s...
