Problems solved by technology

[0004] In the above existing technologies, the first method uses the live broadcast data stored in the server memory or disk cache to support playback, which has relatively large limitations. Due to the limitation of the server memory space, it is often only possible to cache videos that last a few minutes. Streaming, does not support playback for a long time video stream
However, when using local disk storage

Embodiment Construction

[0027] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] The working principle of HLS is to divide the entire video stream into multiple small HTTP-based files for download, and only one file is downloaded at a time. HLS only requests basic HTTP packets and can pass through any firewall or proxy server that allows HTTP data to pass through. HLS is also easy to use for content delivery networks to deliver media streams.

[0029] see figure 1 , an embodiment of the live video playback method in the embodiment of the present invention includes:

[0030] 101. Receive real-time video fragmentation data of video;

[0031] The server receives real-time video segment data of the video. The real-time...

Abstract

The invention discloses a live video replay method. The method comprises the following steps: receiving real-time video fragmented data of a video to respectively store in a cache and file system, acquiring index information of all real-time video fragmented data within a replay time period predetermined before the current time in the cache and file system, generating an index file according to the index information, and sending the index file to a client; and returning the corresponding real-time video fragmented data to the client according to a replay request of the client. Through the adoption of the live video replay method and device disclosed by the invention, any time period replay of the current live video can be realized, and the effectiveness of replaying the live video is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for watching live video playback. Background technique [0002] HLS (http live streaming) is a streaming media network transmission protocol based on Hypertext Transfer Protocol (HTTP, Hypertext transfer protocol) proposed by Apple. [0003] In the prior art, the HLS live video playback technology has the following two methods. The first method is to support the user video playback function by storing part of the live data in the memory of the server or in the cache of the local disk. The second way is to support playback in the form of on-demand after recording the entire program. [0004] In the above existing technologies, the first method uses the live broadcast data stored in the server memory or disk cache to support playback, which has relatively large limitations. Due to the limitation of the server memory space, it is often only poss...
