Abstract

The invention provides an audio and video playing method and device. The method comprises the following steps: obtaining a jitter value of an audio frame and the jitter value of a video frame; determining an audio buffer value and a video buffer value according to the jitter value of the audio frame, the jitter value of the video frame, a preset audio and video buffer maximum value and a preset audio and video buffer minimum value; and determining an audio and video buffer value according to the audio buffer value and the video buffer value. By adoption of the audio and video playing method and device provided by the invention, the audio and video buffer value can be adaptively adjusted.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to an audio and video playback method and device. Background technique [0002] With the popularization of the 4th Generation mobile communication technology (4G for short), the application of video playback is becoming more and more extensive. Users can browse videos online after installing a streaming media player on their terminal devices. [0003] When playing the audio and video data, the streaming media player in the prior art buffers the audio and video data before playing. Generally, the buffer value of audio and video data is a fixed value, and the streaming media player only plays after buffering the audio and video data of a fixed playback length. [0004] However, if the buffer value of the audio and video data is too large, the time for the user to see the first frame will increase; if the buffer value of the audio and video data is too small, the...
