Embodiment Construction

[0065] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0066] figure 1 A schematic flow diagram of a method for obtaining live video slices provided by an embodiment of the present invention; figure 1 As shown, the method includes:

[0067] Step 11: Obtain the reference duration of the slice;

[0068] Here, the network side, specifically the network side server receives the original live source code stream, such as the MPEG-TS code stream sent by the live source MPEG system, because the original live source code stream is continuously sent to the server by the live source system, so the server The processing of the original live source stream received each time is the same, please refer to the following des...

Abstract

The invention discloses a method for acquiring a live video clip. The method comprises steps of: acquiring the reference time length of a clip; determining that the sum of the reference time length and a first preset time length is a first time length and / or determining the difference between the reference time length and the first preset time length is a second time length; acquiring the qth key frame of a current original live source; determining that the initial position of the qth key frame is the initial position of the qth clip; within the first time length and / or the second time length of the initial position of the qth key frame, determining that the initial position of the (q+1)th key frame is the end position of the qth clip when it is determined that the (q+1)th key frame exists; and at the initial position and the end position of the qth key frame, cutting the current original live source in order to form the qth clip, wherein the q is a positive integer. The invention also discloses a server.

Description

technical field [0001] The present invention relates to live video streaming technology, in particular to a method and server for acquiring live video slices. Background technique [0002] The HLS (HTTP Live Streaming) protocol is a dynamic code stream adaptive protocol based on the Hypertext Transfer Protocol (HTTP, Hypertext Transfer Protocol), and is a streaming media transmission protocol proposed by Apple Inc. In recent years, the HLS protocol has been widely used in the field of streaming media, mainly because it uses HTTP protocol transmission, which can adaptively adjust the code rate according to the network bandwidth, such as allowing the server on the network side to store multiple files with different code rates for the same program content. The terminal can adaptively adjust the code rate of the multimedia stream to be downloaded according to the actual network download speed; when the network bandwidth is tight, the terminal can realize uninterrupted playback b...
