Abstract

Described herein is a method for adaptively determining a number of frames of a group of pictures for encoding, comprising the steps of: receiving a video segment to be encoded with the number of frames of the group of pictures for encoding, wherein the video segment comprises a plurality of video frames; and determining a frame number of uncoded video frames before the uncoded video frames of the video segment are coded every time in picture group units, and adaptively determining the frame number of picture groups for encoding based on the frame number of the uncoded video frames.

Description

technical field [0001] The present disclosure relates to the technical field of video processing, and in particular to a method and a device for adaptively determining the frame number of a group of pictures used for encoding. Background technique [0002] When encoding a video sequence, it is usually compressed by reducing spatial and temporal redundancy by performing a prediction process in the spatial and / or temporal domain. In actual compression, various algorithms will be adopted to reduce the amount of data, among which I frame, P frame, and B frame are the most commonly used ones. An I frame is a key frame and belongs to an intra frame prediction frame. Both P-frame and B-frame are inter-frame prediction frames. The difference between them is that P-frame prediction only predicts the value of the current block based on one prediction block, while B-frame prediction allows the current block to be predicted based on interpolation based on two previously coded blocks. ...
