Thanks your answer.
There is another question about the scheduleDelayedTask(duration,x,x).
So how should I set the duration, then the audio and video would be sync.
Currently my every audio's frame is 20000ms. the video frame rate is 25fps..
Now I set the audio's next getframe time is 20000ms, video's next getframe time
is 8000ms.
In such case, I use vlc to access it, it also shows that the audio is "PTS is
out of range". It seems that the audio is too late. So if I slowed the video
send rate, the result is video is "PTS is out range".
So is there any solution to solve it ?

In the videoframesource’s getnextframe, if the buffer is nalu, not
completely frame. So the fPresentationTime and fDurationInMicroseconds should
only be set when the buffer is the last nalu in current frame.
Is it right?
Not quite. "fPresentationTime" should be set for every NAL unit that you
deliver. However, for NAL units that make up the same access unit, the
"fPresentationTime" value will be the same.
Also, if you are streaming from a live source (i.e., from an encoder), rather
than from a file, then you don't need to set "fDurationInMicroseconds" at all.
If, however, you are streaming pre-recorded video (e.g., from a file), then you
will need to set "fDurationInMicroseconds" for the last NAL unit of the access
unit (and leave "fDurationInMicroseconds" for the other NAL units at the
default value of 0).
