Abstract

The invention provides a rate playing method and device of a stream media. The method comprises the following steps: firstly, receiving a playing request message sent by a terminal, wherein the playing request message carries the playing rate; secondly, extracting audio and video frames from audio and video streams according to the playing rate; finally, sending the extracted audio and video frames to the terminal, and enabling the terminal to play audio and video according to the extracted audio and video frames. According to the method, the audio and video frames are extracted from the audio and video streams according to the playing rate, the extracted audio and video frames are sent to the terminal, and the number of frames sent to the terminal per second does not need to be increased, so that the waste of network resources is effectively reduced.

Description

technical field [0001] The invention relates to video data playing technology, in particular to a streaming media double-speed playing method and device. Background technique [0002] With the improvement of broadband network infrastructure, the application of streaming media is becoming more and more extensive. In the streaming media application, the streaming media server reads the streaming media data, including video and audio data, from the media file after receiving the playback request from the user, and transmits it continuously and in real time to the terminal. In a video on demand (Video On Demand, VOD for short) application, the terminal can also send a fast-forward or rewind command to the streaming media server to watch the content before or after the current picture. [0003] Streaming media files are usually very large, so it is necessary to compress streaming media files to reduce storage overhead and transmission bandwidth requirements for streaming media f...
