Embodiment Construction

[0065] The preferred embodiments of the present invention will be described in detail below with reference to 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 used to limit the present invention.

[0066] figure 1 It is a schematic flowchart of a method for acquiring 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 stream, such as the MPEG-TS stream sent by the live source MPEG system. Because the original live source stream is continuously sent to the server by the live source system, the server is The processing of the original live source stream received each time is the same, please refer to the following description.

[0069] The serv...

Abstract

Disclosed is a method for acquiring a live video slice. The method comprises: acquiring a reference time length of a slice; determining a sum of the reference time length and a first preset time length as a first time length, and / or determining a difference between the reference time length and the first preset time length as a second time length; acquiring a qth key frame of a current original live source; determining a start position of the qth key frame as a start position of a qth slice; in a first time length and / or a second time length of the start position of the qth key frame, when it is determined that a (q+1)th key frame exists, determining a start position of the (q+1)th key frame as an end position of the qth slice; and at the start position and an end position of the qth frame, slicing the current original live source to form the qth slice, q being a positive integer. Also disclosed are a server and a computer storage medium.

Description

Technical field [0001] The invention relates to live video streaming media technology, in particular to a method and server for obtaining live video slices. Background technique [0002] The HLS (HTTP Live Streaming) protocol is a dynamic stream adaptive protocol based on the Hypertext Transfer Protocol (HTTP, Hypertext Transfer Protocol), and is a streaming media transmission protocol proposed by Apple. In recent years, the HLS protocol has been widely used in the field of streaming media, mainly due to its use of HTTP protocol transmission, which can adaptively adjust the bit rate according to the network bandwidth. For example, the server on the network side is allowed to store multiple different bit rates for the same program content. Multimedia stream, and 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 achieve uninterrupted playbac...
