Abstract

The embodiment of the invention provides a streaming media processing method and device. The method comprises: in the process of playing a streaming media file, receiving a time shifting instruction from a user, wherein the time shifting instruction includes a target time point; determining the transmission stream (TS) slice corresponding to the target time point according to the slice index file corresponding to the streaming media file; determining the position information of a key frame which is located at the nearest position to the target time point in the TS slice; and playing the TS slice from the position information of the key frame. According to the embodiment of the invention, the streaming media processing method and device are able to directly start to play the TS slice from the key frame located at the nearest position to the time shifting target time point, and therefore, the time shifting accuracy in the process of playing the streaming media file may be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of streaming media, and in particular, to a method and device for processing streaming media. Background technique [0002] With the continuous development of streaming media technology and network technology, users can watch various online videos on terminal devices through the network, and online videos have become an indispensable part of people's daily life. [0003] At present, video websites usually use the HLS (HTTP Live Streaming, dynamic bit rate adaptive technology) streaming media transmission protocol to transmit network video files. Segment the huge network video file on the server side through the HLS protocol, divide it into a large number of TS (TransportStream, transport stream) slices for transmission in the Internet, and generate an m3u8 index file to record the sequence and sequence of each TS slice Duration, through the index file to control the download and pl...
