一种基于FFMPEG的音视频同步算法
A Research on Synchronous Transmission for Audio and Video Based on FFMPEG
摘要
Abstract
In video-monitor system, the synchronous transmission of audio and video is a key issue. The audio and video being out of synchronization was caused by the difference among the size of audio data and video data in the procedure of capturing, transmitting and encoding. To solve these problems, a solution is proposed which defines a data structure to store the time-related frames of audio and video data and control the synchronization of audio and video data through all the procedure. At last, the FFMPEG project is ported to Android device to do the experiment. It turns out that the algorithm proposed in this research has a good effect of synchronization. It can meet the need of synchronization in the specified scenes. At the same time, the new method of audio and video processing of Android platform is proposed, which is of great significance in engineering practice.关键词
