[0003] In the prior art, for the target coding unit, a single encoding is usually performed based on a set of fixed coding parameter values. Once the above coding parameters are determined, the coding parameters of the coding unit will not be adjusted.
In practical applications, the values of the above encoding parameters are usually preset or determined according to the encoding result of the previous coding unit. Although there are similarities between adjacent coding units in the video frame, the differences between these coding units There may also be large differences to a certain extent, so the coding parameters determined according to the previous coding unit may not be the best coding parameters for the current coding unit, which will easily lead to poor coding results of the current coding unit

An embodiment of the invention discloses a video encoding method and device. The method includes traversing values of a first encoding parameter combination of a target object in a target level aimingat the target object in the target level and encoding the target object, wherein the values of the first encoding parameter combination include at least two values; selecting a norm according to a preset first encoding result and determining the optimal encoding result in the encoding result of the target object as the encoding result of the target object and further implementing first encoding parameter combination related encoding of the target object. By applying the scheme provided by the invention for video encoding, a better encoding result can be acquired.
Description
technical field [0001] The present invention relates to the technical field of video coding, in particular to a video coding method and device. Background technique [0002] Video coding, that is, video data compression, is used to eliminate data redundancy of video signals. With the continuous development of digital video services in multimedia applications and the continuous improvement of video cloud computing requirements, the existing wired and wireless transmission network bandwidth and storage resources can no longer support the original video source with a huge amount of data. Therefore, video coding has become the current It is one of the hotspots of research and application at home and abroad. [0003] In the prior art, for a target coding unit, a single coding is usually performed based on a set of fixed coding parameter values. Once the above coding parameters are determined, the coding parameters of the coding unit will not be adjusted. In practical applicatio...
