Great !! :)

Just keep in mind that when remuxing to MP4 container with MP4Box, you need to 
provide the FPS (frames per second) value of the content as MP4Box always 
defaults to 25 fps...

example: MP4Box -add file.h264 -add audio.aac -fps 23.976 output.mp4

btw, did it work with 6 B-Frames and b_pyramid enabled?
