Description
Technical field
The present invention relates to video data processing technology field more particularly to a kind of video flowing slice repeater system and methods.
Background technology
Currently, existing video processing analytical technology is to use single-unit operation, generally adopted to improve video treatment effeciency
It is the hardware configuration for improving single machine.But with the arrival of massive video data, traditional method for processing video frequency single machine fortune
Row is slow, and the epoch are handled in massive video, because the concurrent operation of a large amount of computer resources, realizes analyzed video data energy
The demand being enough rendered adequately treated quite quickly.
It is the physics cutting mode used that existing technology carries out cutting to video flowing.Since video flowing is between frame and frame
The unstructured data stream of serial correlation, physical segmentation can cause that frame is imperfect, the problem of lacking key frame (I frames) after segmentation,
Therefore it needs decoupling to video stream data.A kind of video flowing cutting method based on key frame is proposed, video image is with sequence
It is classified as unit and carries out tissue, a sequence is the data flow after one section of image coding, is started to next key frame with key frame
Terminate.It is cut according to the position of key frame, it is ensured that the frame information that all video segments are necessary to is not in
The problem of lacking key frame and video can not being handled, and existing video flowing retransmission technique can not preferably meet simultaneously
The utilization of row computing resource.
