Audio and Video Synchronization series----A simple synchronization algorithm

On the sending side:
The same time stamp (System time) for audio/video frames at the same moment
Receiving Party:
Save two queues, Audio/video for audio and video that have not been played
1. When each audio frame is received, traverse the video queue at this time to compare the time stamp of this audio frame with the timestamp of each video frame:
1) If the audio frame time is in front of this video frame, the frame plays the audio
2) If the time stamp of the audio and video differs from an acceptable error, the audio/video is played simultaneously (and the video frame is removed from the TV queue)
3) If the video time is before, play the video frame (and delete the video frame from the TV queue)
If the last frame in the video queue is before the audio frame, and the frames in the entire video queue are played, then the video queue will be empty, then the audio queue will be placed.
2. A similar processing is done when the video frame is received by the docking.
