Abstract

The invention discloses a video encoding and decoding method and device and a storage medium. The method comprises the following steps: determining a to-be-decoded video frame; decoding the video frame from the decoded video frame; obtaining a reference decoding parameter of a reference frame associated with the to-be-decoded video frame, wherein the reference decoding parameter comprises at leasttwo of the following parameters:, the number of blocks decoded in a skip mode in the reference frame and the total number of blocks in the reference frame, the first number of blocks decoded in an intra-frame and the second number of blocks decoded in an inter-frame in the reference frame, an energy parameter of a motion vector in the reference frame, the third number of blocks of a first size inthe reference frame and the fourth number of blocks of a second size in the reference frame; and the first size is smaller than the second size; determining a target resolution for decoding the to-be-decoded video frame according to the reference decoding parameter; and decoding the video frame to be decoded by adopting the target resolution. According to the invention, the technical problem of low video encoding and decoding efficiency caused by complex processing operation provided by related technologies is solved.

Description

technical field [0001] The present invention relates to the field of audio and video codec, in particular, to a video codec method and device and a storage medium. Background technique [0002] With the development of digital media technology and computer technology, video is used in various fields, such as mobile communication, network monitoring, network TV and so on. With the improvement of hardware performance and screen resolution, users have increasingly strong demands for high-definition video. [0003] Under the condition of limited mobile bandwidth, codecs usually use the same resolution to encode and decode video frames, which will make the peak signal-to-noise ratio (Peak Signal to Noise Ratio, PSNR for short) relatively low under some bandwidths. In order to overcome this problem, in the prior art, it is proposed to use different resolutions for different video frames to encode and decode, but usually it is necessary to determine the reference processing frame t...
