Abstract

The invention relates to a video coding method and device and a video decoding method and device, and the method comprises the steps: obtaining parameter value of a motion parameter of a first non-keyframe; when the parameter value of the motion parameter is higher than the target threshold value, determining that the encoding mode is switched from the first encoding mode to the second encoding mode, and in the first encoding mode and the second encoding mode, setting only the forward reference frame for the non-key frame; wherein the distance between the reference frame configured by the non-key frame in the second coding mode and the non-key frame is smaller than the distance between the reference frame configured by the non-key frame in the first coding mode and the non-key frame; andencoding the second non-key frame according to a second encoding mode, and encoding the non-key frame after the second non-key frame according to the second encoding mode under the condition that thenon-key frame is further included after the second non-key frame. According to the invention, the technical problem of poor video encoding and decoding flexibility in the prior art is solved.

Description

technical field [0001] The present application relates to the computer field, and in particular to a video encoding method and device, and a video decoding method and device. Background technique [0002] In the current video coding technology, generally only consider the impact of the delay of the coding mode on the user experience, and try to reduce the delay to ensure that the user can have a better experience when playing the video, but this method cannot be played according to different The scene adjusts the video encoding and decoding process, resulting in poor flexibility of the video encoding and decoding process, and cannot provide users with videos suitable for the user's current playback environment. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] The present application provides a video coding method and device, and a video decoding method and device, so as to at least solve the technical problem...
