Comment (by elite_jwp):

 Ok. Thanks.
 But here exists a case:
 I want to change the playback speed in ffplay.exe. So i used the atempo
 filter to do it.
 With 'AV_SYNC_AUDIO_MASTER' mode in ffplay, video is synchronized to
 audio.
 If only changing the audio tempo, it will cause the pts diffrence too big
 and nonsynchronized between video and audio.
 Should i also change the video speed for that purpose?
