this one helps. What about this?
String cmd1 = "-i " + inputpath.mp4 + " " + "-filter:v" + " " + "\"setpts=0.5*PTS\"" + " " + Environment.getExternalStorageDirectory().getAbsolutePath() + "/hij.mp4";

 FFMPEG: Fixing stutter in low-motion areas

help you fix your problem The motion vectors are computed by the encoder (x264), not ffmpeg. Your video remains 1080p, not 360p, for which the given bitrate is very low, so during quantization, subtle changes will get flattened out. There can only one simple filtergraph per output-stream, so code :
-vf "scale=trunc(360*iw/ih/4)*4:360" \
-vf "settb=1/1000" \
-vf "scale=trunc(360*iw/ih/4)*4:360,settb=1/1000" \

Modifying motion vectors in ffmpeg H.264 decoder

will help you It's been a long time i have been out of touch with FFMPEG's code internally.
However, given my experience with inside FFMPEG horrors (you would know what i mean), i would rather give you a simple pragmatic advice.

ffmpeg motion interpolation alternatives or speedup
By : Gino

around this issue I use ffmpeg to create videos, it is awesome tool. I create videos from pictures and need to make them as smooth as possible. I found, that what I need called 'motion interpolation'. I started to search all forums, and found only 3 things can help me: slowmovideo, butterflow and new ffmpeg's filter minterpolate. ,
Is there any ways to motion interpolate frames on GPU?
