Live video replay method and device

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...

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, due to the bottleneck of reading and writing of a single disk, it is impossible to support multi-channel and large-scale program playback.

The disadvantage of the second method is also obvious. After recording the entire program, the program video needs to be transcoded, distributed and other processes before it can be provided to users for viewing. The timeliness of watching live programs is relatively poor.
