A low-latency fast start-up method and device

Abstract

The embodiment of the invention discloses a low-latency quick playing method applied to a server. The method comprises the following steps: receiving a data set uploaded by a first client in real time, wherein the data set comprises video data; storing first sub video data, and modifying a time stamp of each frame in the first sub video data, wherein the first sub video data at least comprises a key frame, which is received recently, in the video data; when a playing request sent by a second client is received, sending the first sub video data to the second client for playing. Therefore, when the playing request sent by the second client is received, the first sub video data of which the time stamps are modified and which can be quickly played over is sent to the second client for playing, namely the second client can quickly play videos without waiting for the next key frame; furthermore, the video playing latency between the second client and the first client is reduced, and the watch experience of a user of the second client is enhanced.

Description

technical field [0001] The present invention relates to the technical field of live video broadcasting, in particular to a method and device for fast broadcasting with low delay. Background technique [0002] RTMP (Real Time Messaging Protocol, Real Time Messaging Protocol) is a protocol for audio, video and data transmission between the player and the server. The RTMP protocol has been widely used in video-on-demand and live broadcast applications. The client (such as the player) can use the RTMP protocol to exchange data with the server. For example, the client can receive video and audio data pushed by the server and play it locally on the client. [0003] However, in the process of RTMP real-time playback, the playback entry point of the client accessing the real-time video is random. In order to ensure the normal playback of the client, when the client accesses the real-time video playback and pulls the stream from the server, the server needs to start sending video ...

AI Technical Summary

Problems solved by technology

If the server starts to send video data to the client from the key frame received after the access time, it will cause the client to wait for the video to start broadcasting (that is, when the client starts to play the live video), and cannot start broadcasting quickly or immediately , which is not conducive to improving the viewing experience of client users
