Problems solved by technology

However, in related technologies, such as the HEVC video coding standard, it is necessary to sequentially traverse the 35 intra-frame prediction modes provided to determine the intra-frame prediction mode with the lowest coding cost among the 35 intra-frame prediction modes. This process is very time-consuming. It affects the coding efficiency of video coding and increases the waiting time of users

Abstract

The invention provides an intra-frame prediction mode processing method, which comprises the following steps of: obtaining a to-be-coded video, and obtaining a to-be-analyzed video clip correspondingto the video to be coded; obtaining a prediction unit corresponding to the to-be-analyzed video clip, and determining smoothness parameters of reference pixels of the prediction unit in multiple directions; determining an intra-frame prediction mode matched with the prediction unit based on the smoothness parameters of the reference pixels of the prediction unit in multiple directions; and processing a to-be-coded video through the determined intra-frame prediction mode to realize coding of the to-be-coded video. The invention further provides a multimedia information processing method and device, electronic equipment and a storage medium. The waiting time for selecting the intra-frame prediction mode of the video can be reduced, and the speed of the video coding process is improved.

Description

technical field [0001] The present invention relates to video coding technology, in particular to a video information processing method, a multimedia information processing method, a device, electronic equipment and a storage medium. Background technique [0002] In the process of encoding multimedia information in the related art, the video encoding system can compress digital video signals. For example, a video encoding system may compress digital video signals to reduce the storage and / or transmission bandwidth of such signals. Video coding systems may include, but are not limited to, block-based, wavelet-based, object-based systems, and / or block-based hybrid video coding systems. Examples of block-based video coding systems may include H.261 (e.g., Moving Picture Experts Group), MPEG-1, MPEG-2, H.263, H.264 / Advanced Video Coding (AVC), and / or H.265 / High Efficiency Video Coding (HEVC). However, in related technologies, such as the HEVC video coding standard, it is ne...
