Realization method of real-time code stream playback control in a video surveillance system

Abstract

The invention discloses a method for realizing real-time code stream playback control in a video monitoring system, belonging to the technical field of real-time code stream playback control, comprising the following steps: S1, making a video control bar; S2, normal playback; S3, double-speed playback; S4 , playback control; S5, video dragging. Create a control bar by obtaining the basic information of the live streaming video, and then set different self-increment through the self-incrementing control point inside the control bar to change the video transmission rate; by logging out of the video object in the browser, modify the local video object id, Let the backend re-push the stream; by modifying the local video object id, a new browser video object is generated, and the live video stream with the drag point as the start time and the end time of the video as the end time, so as to realize the rewind and fast forward of the video , pause, play, double-speed playback and mouse drag functions, which are convenient for artificially adjusting the playback of live streaming video, and are more convenient to use.

Description

technical field [0001] The invention relates to the technical field of real-time bit stream playback control, in particular to a method for realizing real-time bit stream playback control in a video monitoring system. Background technique [0002] With the rapid development of information technology and network applications, new things such as wireless networks, Internet networks, multimedia, long-distance transmission, and broadband communications have undoubtedly changed our work and lifestyle day by day. The study found that the information obtained by humans through vision accounts for about 70% of the information. Video information has the advantages of intuition and observability. Video has a wide range of applications and many functions. Some videos are surveillance videos, which are transmitted to users for monitoring in real time. picture. [0003] Surveillance video is generally real-time stream transmission of video data. The rate of real-time stream transmission...
