| 摘 要： | 为实现音视频同步播放,本文提供了一种多线程的音视频同步控制方法。所述方法采用操作系统信号量、条件变量、系统层定义的节目参考时钟和显示时间戳,从而使得音视频在相同的本地系统时钟的参考下按照PTS时刻严格输出。实例显示能够实现音视频同步。

| Abstract: | In order to realize the synchronous play audio, this paper provides a multithreaded audio synchronization control method. The method has the operating system signal, and the condition variables, system of the definition of the program of clocks and display time stamp reference, thus make the audio and video in the same local system clock under the reference moment strictly in accordance with the PTS output. Instances can realize audio synchronization. |
