Abstract

The invention discloses a method, a client side and a system for self-adaptive playing of FLV (flash video) media streams. The method includes: downloading an FLV index file; when the condition that the current network bandwidth is unmatched with the bitrate of a played FLV media stream is monitored, determining a current key frame of an FLV media stream with the bitrate matched with the current network bandwidth according to the FLV index file; and downloading and playing the FLV media stream with the bitrate matched with the current network bandwidth from the current key frame. The method, the client side and the system have the advantages that by means of computing network access rate, the client side and the system can be automatically switched to the bit stream matched with the bandwidth according to the available bandwidth after the FLV media streams are played, and accordingly network bandwidth influence is weakened, the bandwidth is used more effectively, watching fluency of users is guaranteed more effectively, and playing quality of streaming media is improved.

Description

technical field [0001] The invention relates to the field of playing media streams, in particular to a method, client and system for adaptively playing FLV media streams. Background technique [0002] At present, adaptive mobile streaming media protocols mainly include adaptive RTSP protocol (Real Time Streaming Protocol, real-time streaming protocol), adaptive RTMP protocol (Real Time Messaging Protocol, real-time message transmission protocol), Smooth streaming (smooth streaming) and adaptive HTTP (HyperText Transfer Protocol, hypertext transfer protocol) progressive download (Adaptive Progressive Downloading). The RTSP protocol has been formulated in 3GPP. RTMP and HTTP PD (HTTP Progressive Downloading, HTTP progressive download) have replaced the RTSP streaming media protocol on the Internet. With the increase of the bandwidth of the mobile network, the mobile phone streaming media protocol will also change from RTSP to HTTP PD evolution, this trend has been verified on...
