MP4Box is not an encoder, it is a muxer. So you need to re-encode your content using the JM or FFmpeg/libx264.

I need produced .mp4 file for streaming the video over a network simulator. my next step is to prepare it for streaming by "./mp4trace -f -s 192.168.0.2 12346 out.mp4 > st_a01.st" command. – Tayebe Ghanbari Oct 02 '16 at 08:03
I think maybe re-encoding content by JM damage RTP tracks produced by MP4Box. dont you ? – Tayebe Ghanbari Oct 02 '16 at 08:05
Correct. The encoding occurs before the packaging. – R. Bouqueau Oct 03 '16 at 20:47
