What steps will reproduce the problem?
1. Choose a high resolution 1920x1080 for video recording, and the output video 
lags and stutters badly. Its unusable.
2.
3.

What is the expected output? What do you see instead?
Good quality output, like the output from MediaRecorder in Android.

What version of the product are you using? On what operating system?
JavaCV for Android. FFmpegFrameRecorder.java.

Please provide any additional information below.
Using lower resolutions (upto 1280x720) works fine. When using higher 
resolution, say 1920x1080, the recorded video stutters and audio lags. I am 
looking for any solution that can work. 

I am guessing that the problem is the SD card write. Is it possible to write to 
a memory file, for example, and dump to SD card every so often?

Thanks.

AFAIK, FFmpeg does not support hardware acceleration. Please report upstream, 
and let us know when the support has been added, thanks!
