What steps will reproduce the problem?
1.I use Doubango and imsdroid on android device.And I found this phenomenon 
when an video call between two android devices: no matter what fps i set (by 
MediaSessionMgr.defaultsSetVideoFps(fps)),the actual fps was no more than 
15,average was about 10 in the send end.That is to say,the fps is less than 15 
in the real situation, and can't be biger? 
2.For this low fps, the video to the receiver is not very fluent, if 1080p 
makes it worse.  
3.So in order to get a high fps, how to do?
I have try two solution: one is to use the work thread to deal frame callback 
in android level,and it works well for the local video is very fluent.But the 
remote video is not such better when 1080p.
Another is can I use multi-thread to encode video frame by ffmpeg in doubango?
and how should I do?
What is the expected output? What do you see instead?

Thanks .
