Embodiment 1

[0072] The video playback client receives the user's request to play videos A, B, and C synchronously, and the video playback client sends a link request message to the multimedia server storing videos A, B, and C respectively, requesting to establish a session link, and the multimedia server returns the link establishment As a result, it includes the session identifiers of videos A, B, and C, as well as the starting playback time points of videos A, B, and C. Assume that the starting playback time points of videos A, B, and C are respectively 10 of a certain month and a certain day. :30, 10:00, and 12:00, the video playback client sorts the time parameters of videos A, B, and C, that is, the starting playback time points, according to time, and the following order is obtained:

[0073] Video B-Video A-Video C,

[0074] At this time, the first video that is specifically video B is first played, the time parameter of video B is the target time parameter, the reference time poin...

Abstract

The invention provides a video playing method and device, a video playing client side and a multimedia server. The video playing method applied to the video playing client side includes the steps that when the request for synchronously playing multiple videos from a user is received, the request for building link request information of a conversation link between each video and the multimedia server is sent to the multimedia server storing the multiple videos, and the link request information carries the time parameter of the starting playing time point of each video; when the link building result which is fed back by the multimedia server and carries the time parameters indicates that the link is built successfully, the videos corresponding to the same time point are synchronously played after the videos are sequenced according to the time parameters. The video playing method and device, the video playing client side and the multimedia server can realize synchronous playing of the multiple video files at the same time point.

Description

technical field [0001] The invention relates to the field of multimedia, in particular to a video playing method and device, a video playing client and a multimedia server. Background technique [0002] At present, in the security video surveillance system, in addition to real-time playback of video surveillance images, manual or scheduled recording can also be performed at certain moments for subsequent playback viewing. The recorded video files are generally stored on a network streaming server or a front-end storage device, that is, a multimedia server. When the recorded video file needs to be played, the video playback client will obtain the session link by requesting the multimedia server, and receive the code stream through the real-time transport protocol RTP, obtain the RTP data packet, and then perform data framing, using and sending end The decoding algorithm corresponding to the encoding algorithm decompresses the data packet, and after the video file is restored...
