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?
