Embodiment 1

[0071] figure 2 It is a flow chart of a video encoding method shown according to an exemplary embodiment, such as figure 2 As shown, the video encoding method may include the following steps.

[0072] In step S11, the current prediction block corresponding to the bidirectional prediction frame in the video to be encoded is determined.

[0073] The embodiment of the present invention may be configured to obtain a scene of a merged option corresponding to a prediction block in a B frame during the process of inter-frame prediction.

[0074] Inter-frame prediction refers to using the pixel values ​​of adjacent encoded frames to predict the pixels of the current frame image, so as to effectively remove video temporal redundancy. Since images generally rarely change drastically, the correlation between adjacent frames is generally stronger than the correlation between pixels within a frame, so the compression ratio is greater. Also bigger due to inter prediction. Because most...

[0099] image 3 It is a flow chart of a video encoding method shown according to an exemplary embodiment, such as image 3 As shown, the video coding method may include the following steps.

[0100] In step S21, the current prediction block corresponding to the bidirectional prediction frame in the video to be encoded is determined.

[0101] The embodiment of the present invention can be applied to a scene in which a merged option corresponding to a prediction block in a B frame is obtained during inter-frame prediction.

[0102] The video to be encoded refers to a video that needs to be encoded.

[0103]The bidirectional predictive block is the predictive block in the B frame. The B frame method (Bframe) usually used in inter-frame prediction is an inter-frame compression algorithm for bidirectional prediction. When compressing a frame into a B frame, it compresses the frame according to the difference between the data of the adjacent forward frame, the current frame and ...

Abstract

The invention relates to a video coding method and device, electronic equipment and a storage medium. The method comprises the steps of determining a current prediction block corresponding to a bidirectional prediction frame in a to-be-coded video; when the current prediction block meets a bidirectional prediction limiting condition, acquiring forward motion information of a target block corresponding to the current prediction block, and the forward motion information is used as a merging candidate; and performing video coding on the to-be-coded video according to the merge candidate. According to the method, the bidirectional prediction limitation can be considered in the process of obtaining the merge candidate; according to the method of the present disclosure, the occurrence of invalidcandidates can be significantly reduced, repeated candidates can be effectively clipped, and moreover, the method of the present disclosure can reduce the computational complexity of video encoding and decoding only by referring to forward motion information, and the saved candidate list positions can be configured to try more candidates.

Description

technical field [0001] The present disclosure relates to the technical field of video encoding, and in particular, to a video encoding method, device, electronic equipment, and storage medium. Background technique [0002] Demand for high-resolution, high-quality video such as high-definition (HD) video and ultra-high-definition (UHD) video has increased in various application fields recently. When video data has higher resolution and higher quality, video data is larger in volume than conventional video data. Thus, if video data is transmitted on an existing medium such as a wired / wireless broadband circuit or stored in an existing storage medium, transmission costs and storage costs increase. To avoid these problems encountered with high-resolution, high-quality video data, high-efficiency video compression techniques can be used. [0003] In order to improve the compression efficiency as much as possible, the prediction block in the B frame can be used for both forward ...
