Abstract

The embodiment of the invention provides a synchronous audio and video processing method and device. The method comprises the following steps: decoding a video frame to obtain video data, starting to decoding an audio frame after a first time of starting to decode the video frame to obtain audio data, wherein the first time is a pre-obtained maximum decoding time of decoding one video frame; and playing the video data and the audio data corresponding to each playing time point in sequence. The decoding of the video frame is delayed for the length of the first time after decoding the audio frame, thereby guaranteeing that the video frame has been decoded at the playing time point corresponding to the decoded audio data, and the audio data and the video data can be continuously played to avoid the blockage phenomenon.

Description

technical field [0001] Embodiments of the present invention relate to computer technology, and in particular to a method and device for synchronous processing of audio and video. Background technique [0002] With the popularization of the 4th generation mobile communication technology (English: the 4th Generation mobile communication technology, referred to as: 4G) and smart terminal devices, the application of real-time streaming media is becoming more and more extensive, and users can install different streaming media on smart terminal devices. When the player plays streaming media, it receives the video and audio sent by another device in real time. [0003] In the process of receiving and playing audio and video, the common processing method is: the receiving end device receives audio packets and video packets, obtains the playing time points of audio and video, and then puts the audio frames and video frames into the audio and video frame queue, The data is taken out ...
